Detailed description of the invention
Below in conjunction with accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole realities
Execute example.Generally can be next with various different configurations with the assembly of this utility model embodiment illustrated described in accompanying drawing herein
Arrange and design.Therefore, below the detailed description of the embodiment of the present utility model provided in the accompanying drawings is not intended to limit
Claimed scope of the present utility model, but it is merely representative of selected embodiment of the present utility model.Based on this utility model
Embodiment, the every other embodiment that those skilled in the art are obtained on the premise of not making creative work, all
Belong to the scope of this utility model protection.
Refering to Fig. 1, a kind of optical module being applied to retro-reflecting coefficient test that the present embodiment provides, including standard A light
Source 101, turntable 102, spectroscope 104, diaphragm 105, photo-detector 106 and lens barrel (being not drawn in figure), standard A light source 101,
Turntable 102, spectroscope 104, diaphragm 105 may be contained within lens barrel, and turntable 102 offers loophole 103, spectroscope 104
It is obliquely installed in turntable 102, and spectroscope 104 blocks loophole 103, diaphragm 105 and turntable 102 and is arranged at spectroscope
The left and right sides of 104, photo-detector 106 is positioned at the top of spectroscope 104, and the light reflected through spectroscope 104 is permissible
Collected by photo-detector 106.
Wherein, standard A light source 101 can include electric filament lamp and collimator, the incident beam collimator that electric filament lamp sends
It is incident to spectroscope 104 by loophole 103 after collimation.Electric filament lamp is cheap, low cost, and what electric filament lamp was launched is astigmatism, therefore
Arranging collimator, the astigmatism that electric filament lamp is launched collimates through collimator so that incident beam is the less parallel light of collimation
Bundle, its subtended angle is not more than 0.2 °, and colour temperature is 2856K.If considering based on service life, electric filament lamp can also use white LED lamp
Replacing, LED is long for service life.
Turntable 102 is rotary structure, and it at least can realize viewing angle is 0.2 °, 0.33 °, the rotation of 1 °.
Turntable 102 arranges loophole 103 so that the incident beam that standard A light source 101 is launched can be by this loophole 103 directive
Spectroscope 104.Spectroscope 104 includes that transmission plane and reflecting surface, spectroscope 104 are obliquely installed in turntable 102, spectroscope 104
Transmission plane towards the loophole 103 of turntable 102, the reflecting surface of spectroscope 104 towards photo-detector 106, its angle of inclination
For: the incident beam that standard A light source 101 sends can be transmitted through tested retro reflectors 107 through the projection surface of spectroscope 104, and
Reflect light beam through the second of spectroscope 104 reflection and can enter photo-detector 106.
Normally, photo-detector 106 includes photoelectric sensor, such as silicon photo diode, is used for collecting tested retro reflectors
107 retroreflective light reflected.It is preferred that in the present embodiment, photo-detector 106 also includes light filter, by filtering
Device can filter and use veiling glare unnecessary present in environment, it is to avoid the interference that certainty of measurement is caused by veiling glare, improves and measures
Accuracy.
In the present embodiment, it is preferred that photo-detector 106 also includes that luminous flux limits device, it is used for limiting tested reflex reflection
The light flux collection angle of the retroreflective light that body 107 reflects.Luminous flux limits device and is arranged at the front of silicon photo diode,
The retroreflective light that tested retro reflectors 107 reflects first passes through luminous flux and limits after device carries out the restriction of light flux collection angle
Absorbed by photoelectric sensor again.Luminous flux limits device can be arranged at the front or behind of light filter.
Optical module total in the present embodiment is the compactest, and reflection light may be caused dry by illuminating ray
Disturb, cause received retroreflective light can not accurately reflect out actual reflecting effect, make measurement result distortion.Therefore, this reality
Executing in example, on the one hand lens barrel inwall is provided with delustring screw thread, and on the other hand, lens barrel inwall does the black process of dye, eliminates illumination with this
The light interference to retroreflective light, improves the precision measured.
More preferably, in the present embodiment, in lens barrel, it is additionally provided with diaphragm fixed support 108, for fixed aperture 105, ensures light
There is not change in location because shake waits in door screen 105, and then guarantee is incident to the incident ray of tested retro reflectors 107 or through tested
The reflection light of retro reflectors 107 reflex reflection is not interfered.It is additionally provided with fixing seat 109 in lens barrel, is used for fixing spectroscope
104, ensure that certainty of measurement does not receives impact because of the change in location of spectroscope 104.
The incident beam that standard A light source 101 sends sequentially passes through the loophole 103 on turntable 102, spectroscope 104, light
Door screen 105 is transmitted to tested retro reflectors 107, and the first reflection light beam obtained after tested retro reflectors 107 reflects is through diaphragm 105
Being incident to spectroscope 104, the second reflection light beam obtained after spectroscope 104 reflects enters photo-detector 106, by photo-detector
106 absorb, and complete the measure of coefficient of against glint of tested retro reflectors 107.The angle that incident beam and the first reflection light beam are formed
Less than or equal to 0.2 °.Owing to the viewing angle of reflex reflection is the least, so more difficult reality in the converse light path of retroreflectometer
Photo-detector 106, and consideration based on compact conformation, therefore, the optical module in the present embodiment are arranged in existing enough spaces,
The most directly collect the retroreflective light through the reflection of tested retro reflectors 107, but beam splitter is set, by beam splitter to tested
First reflection light beam of retro reflectors 107 reflection carries out secondary reflection again, is just collected by photo-detector 106 after secondary reflection again, this
Sample can reduce the structure of optical module, and then reduces the structure of retro-reflecting coefficient tester.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
