Imaging quality measurement of digital light processing projection system

SHEN Hui-liang,MOU Tong-sheng,HUANG Dan-dan,YANG Dong-xiao,LI Zhi-neng(College of Information Science and Engineering,Zhejiang University,Hangzhou 310027,China)  
A method was proposed to evaluate the imaging quality of digital light processing(DLP) projection system based on optical modulation transfer function(MTF).The proposed method detected the fast switching timing of digital micromirror device(DMD) from green-field signal,and achieved the synchronization of DMD switching,exposure times of 9 charge coupled device(CCD) cameras,and image capturing.The quality of the captured DMD image was evaluated using fast Fourier transforms along x and y directions.Three objective indexes were proposed based on the amplitudes of second-order MTFs to measure the minimum,average and deviation of imaging quality,respectively.Experimental results indicate that the proposed method is accurate and stable,and can be applied for imaging quality measurement in DLP quality control.
