A high speed, high-resolution flow imaging system is modified to achieve extended depth of field imaging. An optical distortion element is introduced into the flow imaging system. Light from an object, such as a cell, is distorted by the distortion element, such that a point spread function (PSF) of...http://www.google.com.tw/patents/US8005314?utm_source=gb-gplus-share專利 US8005314 - Extended depth of field imaging for high speed object analysis
