a novel solar illumination system consisting of strip plane mirror array collecting sunlight, light pipe, coupling mirror and grinded plastic tray scattering light was introduced.
adopting spherical mirror and plane mirror can notablely improve the utilization of the light source in the system of light source.
在光源系统中采用球面聚光镜和平面反射镜,可大幅提高光源的利用率。
this is certainly true for a plane mirror but it is only approximately the case for other configurations .
对于平面镜这肯定是对的,但是对于其它形状的反射镜则情况只是近似如此。
the theory and the experiment can prove that on a certain condition a plane mirror also could produce real images.
理论和实验都可以证明,在一定条件下,平面镜能够生成实像。
the image and material object of plane mirror are simultaneously photographed on negative.
把平面镜的映像和实物同时拍摄成底片。
according to the first-order wave aberration theory, the permissible tolerances of the plane mirror in the autocollimating test have been derived.
根据初级波面像差理论,推导了自準检测法中平面反射镜的误差允许值。
the processing results show that the plane mirror still has enough stiffness even if its lightening ratio is as high as 44.5%, and there is no deformation that will affect processing accuracy.
