Referring to figure 2., Fig. 2 is a kind of process of the service life detection method of window mirror provided in an embodiment of the present invention
Figure, described method includes following steps:
Step S110: when i is M, window mirror window after the test of i-th dust storm in dust storm chamber is obtained
The i-th laser light transmission rate of the optical mirror slip of mirror.
Window mirror needs window mirror carrying out mode as shown in Figure 3 to carry out when being tested using dust storm chamber
Installation, the window mirror include optical mirror slip, life tests are carried out to window mirror in the present embodiment, substantially to optical mirror slip
Carry out life tests.In the installation process of window mirror, lens supports and locating rack are relatively arranged on the both ends of bottom plate, optics
Outwardly, reverse side is pasted and fixed in lens supports and guarantees to be fully sealed, the output of laser light source in the front (film plating layer) of eyeglass
End connection collimating mirror, the collimating mirror are set on locating rack, and light power meter is set in lens supports and is located at the eyeglass branch
Between frame and the locating rack, it is evenly distributed with multiple light holes in the lens supports, is evenly distributed on the locating rack
The position of multiple location holes, the light hole and the location hole corresponds, and center spacing is 35mm, test process
In, light power meter is placed on to an optical power of testing laser light source between lens supports and locating rack, then in optical frames
The secondary optical power of the positive re-test laser light source of piece obtains the first of optical mirror slip divided by an optical power with secondary optical power
Beginning laser light transmission rate.
Wherein, the quantity of the light hole and the location hole is 13.
Before carrying out dust storm test using dust storm chamber, light hole is blocked with screw first, in test process, light function
It is placed in the outside of dust storm chamber under rate meter, collimating mirror and laser light source are desirable, remainder is placed in dust storm chamber
Interior, dust storm is positive in dust storm chamber vertically blows to optical mirror slip, and dust storm stops blowing sand after testing per half an hour, takes out dust storm
Device in chamber is without any processing, then shows light power meter, collimating mirror and laser light source according to installation shown in Fig. 3
Intention is installed, and then successively taking i is 1 to M, can measure window mirror in dust storm chamber after the test of i-th dust storm
The i-th laser light transmission rate of the optical mirror slip of the window mirror, M are the positive integer greater than 1.
Wherein, laser light transmission rate is counted after being transferred to electronic equipment by the above-mentioned detected optical power of light power meter
It calculates.
In addition, as an implementation, since lens supports are equipped with multiple light holes, the position of location hole and light hole
One-to-one correspondence is set, so, step S110 includes:
Step S111: when i is M, it is described after the test of i-th dust storm in dust storm chamber to obtain the window mirror
On the optical mirror slip of window mirror in N number of point each point i-th eyeglass dot laser light transmittance.
It is to be appreciated that N number of point is above-mentioned multiple light holes on optical mirror slip, since laser light source transmitting laser is logical
Location hole transmitting is crossed, so optical mirror slip can be placed in some and transmitting when detecting the laser light transmission rate of optical mirror slip
At the corresponding light hole of the position of positioning hole of laser, the laser light transmission rate of some point on optical mirror slip is thus measured, for example,
Optical mirror slip can be also fixedly placed in lens supports, optical mirror slip can cover multiple light holes, thus can emit laser and arrive
Corresponding light hole detects the laser light transmission rate of optical mirror slip with this.
So obtaining N number of point on optical mirror slip is really corresponding N number of light hole, N is the positive integer more than or equal to 1.
Step S112: the average value of the i-th eyeglass dot laser light transmittance of N number of point is calculated, the average value is made
For the i-th laser light transmission rate of the optical mirror slip.
For example, thus obtaining the 5th eyeglass point of N number of point on optical mirror slip in the 5th if M is 5, i when being 5
Laser light transmission rate, so the eyeglass dot laser that can use N number of point of optical mirror slip is saturating in order to obtain the laser light transmission rate of optical mirror slip
The average value of light rate, then using the average value as the 5th laser light transmission rate of the optical mirror slip, then for obtaining every time
The mountable aforesaid way of the laser light transmission rate of optical mirror slip obtains.
In addition, as another embodiment, the i-th laser light transmission rate of optical mirror slip can also be the N of optical mirror slip
The eyeglass dot laser light transmittance of the maximum point of eyeglass dot laser light transmittance in a point, or be eyeglass dot laser light transmission in N number of point
The eyeglass dot laser light transmittance of the smallest point of rate, or median can also be in for eyeglass dot laser light transmittance in N number of point
The eyeglass dot laser light transmittance of point, it is, of course, also possible to i-th of the eyeglass dot laser light transmittance for taking other to put as optical mirror slip
Laser light transmission rate.
Step S120: judge whether the i-th laser light transmission rate is less than preset value.
So in order to obtain the relationship that laser light transmission rate changes over time, so need to obtain multiple laser light transmission rate,
If i-th laser light transmission rate is less than preset value, step S130 is executed: stopping carrying out the dust storm test to the window mirror,
Obtain M laser light transmission rate.
Since in test, the initial laser light transmittance of optical mirror slip is more than or equal to preset value, so, until light is arrived in test
When learning the laser light transmission rate of eyeglass less than preset value, stop carrying out the dust storm test to the window mirror, so, it can get M
Secondary laser light transmission rate.Wherein, preset value can be any one value in 0.8-0.9, due in practical application, optical mirror slip just
Beginning laser light transmission rate is more than or equal to 90%, so preset value can be 0.9.Certainly, preset value can also according to actual needs into
Row flexible setting.
Step S140: laser light transmission rate variation relation is obtained based on the M laser light transmission rate.
So in the manner described above, i can be obtained as 1 to the total M laser light transmission rate of M.
As an implementation, using least square method, the M laser light transmission rate is fitted to obtain index point
Cloth parameter is then based on the exponential distribution model parameter and determines the variation relation changed over time for characterizing laser light transmission rate
Mathematical model.
Least square method refers to a kind of mathematical optimization techniques, it finds data most by minimizing the quadratic sum of error
Nice function matching.The data and reality that can easily acquire unknown data using least square method, and these are acquired
The quadratic sum of error is minimum between data, and least square method can also be used in curve matching.Some other optimization problem can also lead to
It crosses minimum energy or maximizes entropy and expressed with least square method.
For example, mathematical model can be y=ax, wherein a is above-mentioned exponential distribution model parameter, so by above-mentioned
M laser light transmission rate of acquisition, due to obtain every time laser light transmission rate can separated in time, so, x indicate the time, y indicate
Laser light transmission rate can determine above-mentioned model if can get the value of a stable exponential distribution model parameter a with this.
Step S150: the service life of the window mirror is determined according to the laser light transmission rate variation relation.
It can determine the service life of the window mirror after above-mentioned acquisition laser light transmission rate changes over time relationship, for example,
The service life that the window mirror can be determined according to above-mentioned mathematical model, when such as testing the service life of some window mirror,
The laser light transmission rate for measuring window mirror through the above way, then brings into mathematical model, can calculate x with this, x is window mirror
The used service life.
In the embodiment of the present invention, the use longevity of window mirror can be obtained with this by the laser light transmission rate of acquisition window mirror
Life, it is possible thereby to by the service life of assessment window mouth mirror come the performance of assessment window mouth mirror, so as to avoid the personnel of needing repairing
The problem of scene checks, waste of manpower cost.
