Paper Abstract

A novel method of high speed grating-generated electronic coherence microscopy is applied to produce depth-lateral images of biological tissue without axial-lateral scanning. Axial-lateral scan is automatically performed by the stationary reflection diffraction grating installed in the Littrow configuration at the reference beam and a cylindrical lens installed in the sample beam. Using several 2D CCD array complex digital imags containing amplitude and phase values the depth-lateral reflections of biological tissue are reconstructed with a simple algorithm. The depth scan of 1.5 mm and the transversal coordinate image about 1.2 mm of the chicken tissue with a depth resolution of 17 micrometers , and a dynamic range about 70 dB are achieved. Final depth-lateral images are similar to OCT images and produced without any moving parts.
