Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
This utility model relates generally to a kind of rearview mirror reflectance test instrument, as shown in Figures 1 and 2, including collimated light
Source 1, detector 2, integrating sphere 3, calibration plate 4, casing 5, data process and display module 6.Integrating sphere 3 is used to collect reflection light,
Through being repeatedly fairly evenly scattered in inside integrating sphere after diffuse-reflectance inside integrating sphere, improve the stability measuring light, thus
Improve certainty of measurement.
As shown in Figure 1 and Figure 3, detector 2 uses the photodetector meeting simulation human eye vision function, detector 2
Put into the detector mouth on integrating sphere 3, fixed by screw；Integrating sphere 3 is fixed on the fixing of casing 5 by four sunk screws
On dish 51.Collimated light source 1 uses CIE A light source to meet test needs collimated light with optical lens combination.Collimated light source 1 is placed on
In the light cylinder of integrating sphere 3, and adjust the collimated light source 1 position in the light cylinder of integrating sphere 3 by three jackscrews 11, make collimation
The aperture of light source 1 is positioned at integrating sphere 3 and detects mouth center, locks jackscrew 11 and fix after adjustment.
As shown in Figure 2, casing 5 uses exquisite aluminum hull cabinet, and light and beautiful, bottom is provided with 4 rubber feets 52, subtracts
Few vibrations.Data process and display module 6 is fixed by screws on casing 5.Data process and display module 6 is arranged on casing
The front portion of 5, data process and display module 6 is made up of touch screen and single-chip microcomputer, are processed by data and touch in display module 6
Touch screen control, operate easier, improve test speed.
During utility model works:
As shown in Figures 1 and 2, the incident illumination of collimated light source 1 is being amassed through integrating sphere 3 direct irradiation by 25 ° of angles
Bulb separation 3 detects the calibration plate 4 at mouth, produces reflection light and injects in integrating sphere, makes after the internal repeatedly diffuse-reflectance of integrating sphere 3 non-
Often it is scattered in integrating sphere 3 equably internal, is processed by data after carrying out multiple spot calibration process with display module 6, by rearview mirror
It is put in integrating sphere 3 and detects replacement calibration plate 4 at mouth, record rearview mirror reflectivity values.Data process and display module 6 is by touching
Screen and single-chip microcomputer form.Employing touch screen controls, and facilitates experimenter to operate, straight by the calibration plate 4 of different reflectivity
Connect and detector 2 can be carried out multiple spot calibration, improve detector 2 certainty of measurement, thus accurately measure the reflectivity values of rearview mirror.
Casing 5 uses exquisite aluminum hull cabinet, light and beautiful.
