Paper Abstract

This paper discusses the selection of parameters and the design of a CMOS detector for use in a structured illumination technique implemented with a 4M device (Miniaturized Multi-Modal Microscope) for precancer detection. To obtain real time sectioning the framing rate was set on the order of 500 frames / sec. 500 images allow us to obtain 8 to 16 sections / sec reconstructed from 16 to 64 images. The reconstruction technique is a sine approximation algorithm. To obtain a 1 μm spatial resolution, the required pixel size is 4 μm with a magnification 4:1. The field of extent of 250um required approximately 350 x 350 array size.
