Abstract

A method of optical transmission imaging of strongly scattering objects is proposed, based on point-by-point spatial scanning of a beam of pulsed-periodic laser radiation over the surface of the object under study and recording the number of transmitted light pulses at each scanning point using a patented photoreceiver that selectively registers short light pulses regardless of the level of background illumination. The conditions for obtaining “proportional” and “contour” images of model and biological objects are determined. The features of the method are a low level of required average radiation power, high image recording speed, and a wide operational spectral range, which makes it promising for use in biomedical diagnostics, materials quality control, security, and other areas.
