查询词典 optical lens

Based on the prior art, the optical engine according to the invention has the improvements that, three optical axis steering components are respectively introduced into red, green and blue light illumination systems, and an optical axis lengthening structure is introduced into the green light illumination system, so that optical axes of the red, green and blue light illumination systems, each of which is from an LED resource to the optical axis steering component, are counterclockwise rotated for 90 degrees, parallel with each other, parallel with an optical axis of a projection lens, arranged in a same plane and positioned under the projection lens, luminous faces of three LED luminous chips of the red, green and blue light illumination systems are in a same plane, and the three LED luminous chips can be mounted on a same heat-radiating plate, therefore, the heat-radiating system has a simplified structure, and the optical engine has reduced size.

在背景技术所述的光学引擎的基础上作以下改进，在红、绿、蓝光照明系统中引入三个光轴转向器件和在绿光照明系统中引入光路加长结构，旨使：红、绿、蓝光照明系统各自的从LED光源至光轴转向器件部分的光轴朝逆时针方向转动90°、互相平行、与投影镜头的光轴平行、居同一平面和位于投影镜头的下方，红、绿、蓝光照明系统的三个LED发光芯片的发光面居同一平面，三个LED发光芯片可安装在同一块散热平板上，散热系统的结构简化，所述的光学引擎的尺寸减小。

We placed the lens holder, testing lens, and the assistant lens in the testing optical path. When the testing lens was mounted in the lens holder, we took five dynamic interferograms. After rotating the testing lens by 180 degrees along the edge of the testing lens, we took another set of interferograms. Then, we could evaluate the centering error of the testing optical element by analysing these two sets of interferograms.
