Abstract

This paper is the third of a three-part sequence. A modified Fourier spectrum analyzer system that uses an optical transducer to contain cell images is described. The photoconductor – liquid crystal transducer modulates a transmitted laser beam producing a high contrast cell image. The transducer is operated in a light scattering mode to achieve a contrast ratio in excess of 1000:1 and a gamma of about 10. Cell discriminant features are obtained from the transform spectrum of the transducer modulated image. The ability to classify cells from feature measurements is comparable with previous cell-by-cell classification performance based on cell photography.
