Abstract
The design characteristics of the DLP pocket projector divide it into two parts. The illumination system is one of them. It has LEDs in red, green, and blue. In order to illuminate the dichroic filter collimated, each of them has a collimator. It combines three wavelengths of light through dichroic filters. The micro-lens array, condenser, and TIR prism are the final components that are used to uniformly illuminate DMD and reduce the size of the illumination system. The imaging system is the other. In accordance with the DMD standard; the point of view, successful central length, the relationship of imaging and item and imaging nature of the focal point can be characterised. The lens was well-designed and conformed to the standards thanks to the use of optical simulation software like Code V and ZEMAX. In the end, the production tolerance was looked at. In this plan, the typical light productivity of three frequencies Drove on DMD is 51.13%, and the typical consistency on DMD is 95.17%. The average uniformity and light efficiency of the screen are 87.3% and 44%, respectively.
