Description
Technical field
The present invention relates to communication and sensory field, in particular to the fiber end face surveys that go out light, fibre-optical bending light leakage optical power
Amount, specifically a kind of light power meter receiving transducer.
Background technique
Common light power meter receiving transducer intercepts and captures light mainly by biggish photosurface sensor, and optical signal input will use up
It may then need connector being transferred to flange if light goes out light by fiber connector end face close to the photosurface of sensor
Disk, so that optical signal collects in photosurface as far as possible.Which requires optical signal input position is opposite with photosurface to keep solid
Fixed ability accurate work, limits use scope and operating flexibility.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, and provide a kind of light power meter receiving transducer.This smooth function
Rate meter is at low cost, easy to use, applied widely, can improve detection efficiency.
Realizing the technical solution of the object of the invention is:
A kind of light power meter receiving transducer, including reflection centrum, it is unlike the prior art, described to penetrate centrum as both ends open
The unequal cavity of bore, the small one end of cavity hatch bore are incident optical port, and the big one end of cavity hatch bore is emergent light
Mouthful, outgoing optical port is connected with condenser lens, and condenser lens is abutted against wide photosurface sensor, and it is in circular cone that the inner wall of the cavity, which is equipped with,
Curved reflecting surface.
The incidence optical port was reflecting surface focus and perpendicular to the section of reflecting surface symmetry axis.
The reflecting surface of the reflection centrum inner wall is paraboloid, into reflecting surface light can be reflected into be approximately parallel to it is anti-
The directional light of face symmetry axis is penetrated, mirror surface can reflect centrum inner wall with the optical signal of high reflectance reflective operation wave band
Reflecting surface effect is that the light entered from incident optical port is changed direction, makes it to enter focusing with smaller axial angle thoroughly
Mirror, or the reflection through reflecting centrum inner wall reflecting surface, can reach condenser lens, use reflection centrum inner wall reflecting surface
Afterwards, it can be improved the efficiency for collecting light.
The primary optical axis of the condenser lens and the symmetrical overlapping of axles of reflecting surface.
The condenser lens is one kind of convex lens, Fresnel Lenses or gradual index lens, to reach convergence light
Purpose.
The photosurface of the width photosurface sensor is parallel to the focal plane of condenser lens, the center of wide photosurface sensor
Near the primary optical axis of condenser lens, to reach receiving efficiency maximization.
In use, sweeping optical fiber approaches incident optical port, the optical signal a part revealed in optical fiber is by centrum inner wall
Reflective surface is to condenser lens, and another part optical signal revealed in optical fiber directly reaches condenser lens, above two feelings
The light of condition is focused lens focus to wide photosurface sensor.
This light power meter is compared with current existing light power meter receiving transducer, optical signal input position in use
Tolerance it is stronger, the scope of application is wider, not only can be with the output power of the common optical fiber connector of direct detection, can also be straight
The optical power that Output optical power, the fibre-optical bending of detection bare fibre leak is connect, it, can without using optical fiber jump cable
With the Output optical power of optical fiber connector flange in direct detection Optical Distribution Frame.
This light power meter is at low cost, easy to use, applied widely, can improve detection efficiency.
Detailed description of the invention
Fig. 1 is the structural profile illustration in embodiment.
In figure, 1. reflection 2. reflecting surface of centrum, 3. condenser lens, the 4. incident optical port 6. of wide photosurface sensor 5. goes out

Specific embodiment
The contents of the present invention are further elaborated with reference to the accompanying drawings and examples, but are not to limit of the invention
It is fixed.
Referring to Fig.1, a kind of light power meter receiving transducer, including reflection centrum 1, it is described to penetrate centrum 1 as both ends open bore
Unequal cavity, the small one end of cavity hatch bore are incident optical port 5, and the big one end of cavity hatch bore is outgoing optical port 6,
Outgoing optical port 6 is connected with condenser lens 3, and condenser lens 3 is abutted against wide photosurface sensor 4, and the inner wall of the cavity is equipped in circle
Bore curved reflecting surface 2.
The incidence optical port 5 was 2 focus of reflecting surface and perpendicular to the section of 2 symmetry axis of reflecting surface.
The reflecting surface 2 that this example reflects 1 inner wall of centrum is paraboloid, and the light into reflecting surface 2 can be reflected into less parallel
In the directional light of 2 symmetry axis of reflecting surface.2 surface of reflecting surface can reflect vertebra with the optical signal of high reflectance reflective operation wave band
Internal 2 effect of wall reflecting surface is that the light entered from incident optical port 5 is changed direction, is made it with the entrance of smaller axial angle
To condenser lens 3, or the reflection through reflecting centrum inner wall reflecting surface 2, condenser lens 3 can be reached, reflection centrum is used
After inner wall reflecting surface 2, the efficiency for collecting light can be improved.
The primary optical axis of the condenser lens 3 and the symmetrical overlapping of axles of reflecting surface 2.
The condenser lens 3 is one kind of convex lens, Fresnel Lenses or gradual index lens, to reach convergence light
Purpose.
The photosurface of the wide photosurface sensor 4 is parallel to the focal plane of condenser lens 3, wide photosurface sensor 4
Center is near the primary optical axis of condenser lens 3, to reach receiving efficiency maximization.
In use, sweeping optical fiber 7 approaches incident optical port 5, the optical signal a part revealed in optical fiber 7 is by centrum
Wall reflecting surface 2 is reflected into condenser lens 3, and another part optical signal revealed in optical fiber 7 directly reaches condenser lens 3, above-mentioned
The light of two kinds of situations is focused lens 3 and focuses on wide photosurface sensor 4.
