Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please with reference to Fig. 1 to Fig. 3, the brightness uniformity detection system of specular removal 3D optical projection system provided by the invention comprises ccd array unit 1 and brightness uniformity design sketch generation module 2.
Wherein, ccd array unit 1 is positioned at metal curtain front, for detecting the brightness of projected image.It comprises a substrate, and this substrate is provided with some CCD, the brightness of respective regions on each CCD correspondence detection metal curtain.Brightness uniformity design sketch generation module 2 is connected with ccd array unit 1, for the result of detection according to ccd array unit, generates the design sketch including the monochrome information of metal curtain regional.The design sketch generated as shown in Figure 4.
Receiving the light reflected generate heat for avoiding ccd array unit 1 and affect serviceable life, being provided with on substrate with heat-conducting plate especially, for the heat of convergence is distributed.
What consider again that metal curtain reflects is left-handed or right-circularly polarized light, ccd array unit 1 only needs to detect this left-handed or right-circularly polarized light, for having avoided surround lighting or other light interference detection results, the present invention is provided with the filtering layer only allowing circularly polarized light to pass through on the surface of ccd array unit 1, ensure the accuracy of detection.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
