Using pico-LCoS SLMs for high speed cell sorting

摘要

We propose the use of consumer pico projectors as cost effective spatial light modulators in cell sorting applications. Thematched filtering Generalized Phase Contrast (mGPC) beam shaping method is used to produce high intensity opticalspots for trapping and catapulting cells. A pico projector’s liquid crystal on silicon (LCoS) chip was used as a binaryphase spatial light modulator (SLM) wherein correlation target patterns are addressed. Experiments using the binaryLCoS phase SLM with a fabricated Pyrex matched filter demonstrate the generation of intense optical spots that canpotentially be used for cell sorting. Numerical studies also show mGPC’s robustness to phase aberrations in the LCoSdevice, and its ability to outperform a top hat beam with the same power.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
