A new optical engine consisting of LEDs
rectangular CPC
rectangular lens array and micro display chip DMD is designed by using of KOLA illumination algorithm for micro-projection display. Detail description and analysis of the rectangular CPC and rectangular lens array are provided. The influence due to the size of rectangular CPC and rectangular lens array is analysed for illuminance uniformity on the DMD chip and light energy efficiency of the optical engine system by software ZEMAX. Based on the analysis of parameter of rectangular lens array
the size of rectangular lens array more decrease the illumination uniformity. Experimental results show that the proposed illumination light optical engine can obtain perfect rectangular focula with higher light uniformity more than 90 % and higher energy efficiency of 40 % to meet the needs of micro-projection display
at the same time the designed illumination optical engine compared with other uniformizing light algorithm have advantages such as: lesser capacity
high illumination uniformity. 2010 Copyright SPIE - The International Society for Optical Engineering.

Detection sensitivity is an important parameter of star tracker
which can express detection limit of the weakest detected visual star magnitude. Detection sensitivity of APS star tracker is related to APS parameters
optical system aperture and lens permeance rate
SNR
and so on. This paper
the expressions of APS star detected signal and APS noise are given
so signal-noise ratio (SNR) of star tracker can be obtained. And based on the theory inspecting signal from noise and optimal SNR threshold detection principle
the detection sensitivity model can be obtained. The corresponding APS star tracker detection limit is obtain based on APS IBIS5 and general optical system parameter design. When SNR threshold is 8.1 which can obtain 99.9% detection probability
we can calculate that the detection sensitivity is 6.5 visual magnitude.
