Description
Technical field
The utility model relates to field of photoelectric technology, the projection display equipment that specifically a kind of laser ranging is looked in the distance.
Background technology
Existing telescope type range finder using laser has following several problem:
(1) adopt Nonopaque type liquid crystal LCD in light path, to show the range finding character information; Because the structure of LCD is made up of polaroid and liquid crystal, it is bigger to the attenuation ratio of light, can reduce telescopical transmittance; In addition because LCD oneself is not luminous; It leans on the transmitted light character display of telescopical object lens, therefore can't see ranging information, influence range finding observing effect when dark observing the relatively darker target or the colour of sky.
(2) just be located on the focal plane of light path owing to LCD; Therefore as long as the very high LCD screen of the requirement of LCD is had some the dust of (diameter 0.01mm) or the flaw on the LCD product is exactly a waste product; Domesticly can do the LCD producer that laser range finder uses and have only a family at present; Therefore the cost of product only this item is just very high, and in process of production to the requirement of production environment and operator's requirement also than higher.
The utility model content
The purpose of the utility model is to solve the problem of above-mentioned range-finding telescope LCD, and a kind of projection display equipment of laser rangefinder telescope is provided.
The projection display equipment of the laser rangefinder telescope of the utility model constitutes: be made up of optics of telescope part and information projection display part; Telescopic system is made up of objective lens and eyepiece group, and the Projection Display part is made up of projection display screen, projection condenser, projection catoptron, red mirror; Object lens and eyepiece are formed telescopic system, and the image planes of this telescopic system are provided with a red mirror.Telescope objective group and eyepiece group are on same axis, and the projection catoptron is installed in the upper left side of red mirror, the projection condenser be arranged on the projection catoptron under, below the projection condenser, be projection display screen.
The collection of ranging data information is to carry out Laser emission and receive reflector laser through special laser pick-off loop through telescopical objective lens optical system.When needs carried out laser ranging, main circuit board signaled to laser emitting module and produces beam of laser under operating personnel's control, and it is launched measured target through telescopical objective lens.Received by the laser pick-off objective lens through laser after the reflection of measured target, laser is accepted module through laser and is changed into electric signal and pass back to main circuit board then.Main circuit board accomplish that signal data is handled and with The measured results show on LCD or OLED screen, show on telescopical image planes through optical projection system then.
A red mirror ruddiness that the projection of reflector laser range measurement system is come and telescopical light path is had no influence, when using the telescope object observing, the picture that is observed target is formed on these image planes.After startup laser ranging part is carried out the laser ranging operation to target; Measurement data just partly is presented on the image planes through Projection Display together with relevant information; Telescope picture that the picture that is observed object and information projection are shown is formed by stacking and images in simultaneously on the telescopical image planes like this, then the operator just can be behind eyepiece interference-free gem-pure object observing and observation measurement data.This has just thoroughly eliminated and has adopted a little less than the transmittance that Nonopaque type LCD display mode produced, the problem that dark target or dark situation can't observed data.
Projection display screen is an information display screen that is made up of liquid crystal or OLED; Its luminous wavelength is in the red light of 620-680um wave band; It is by singlechip CPU drive controlling display message; As shown in Figure 3, middle tracking cross is the accurate heart of aiming testee, and following numeral and letter are to measure numeral and unit.
The projection condenser is that a ruddiness filters condenser, and it projects to the image focusing of projection display screen on the red mirror on the telescope image planes.
The projection catoptron is a plane mirror, and its effect is the direction that changes projected image, and it finally reflexes to projected image on the telescopical image planes.
Red mirror is a level crossing that passes through white light reflection ruddiness; Its effect is to let the observed subject image white light of telescope normally see through; But the most of reflection of the ruddiness that optical projection system produces; The projected image that need to show so just can high-contrast be presented on the telescopical image planes, thereby the function that realization can normally be found range evening on daytime.
Projection display equipment with the laser rangefinder telescope of the projection display equipment of the utility model preparation; In optical system, do not block the display screen of light path; And adopt the technology of optical projection to come display message; Therefore it does not influence the transmittance of optical system, can influence telescopical observing effect at no time.And owing to be that self can be luminous, so can both use in any environment, the operator just can be behind eyepiece interference-free gem-pure object observing and observation measurement data.The projection display equipment laser rangefinder telescope production cost of using the utility model is low, and market outlook are very good.
