A Device for Recording TV Images with High Intensity Resolution and Stroboscopic Recording Mode

Resumo

A device for providing registration of grayscaled images that are formed by an analog television camera with transformation of the intensities of discrete spatial samples of an image into a 10-bit digital code is described. A method for visualizing the images with a high intensity resolution on the screen of a typical monitor, which provides rendering of more than 1000 gray tones, is proposed and its practicality is discussed. The method of implementing the stroboscopic mode of recording physical processes, which are initiated by the action of electrical pulses of the signal source, is described and the results of its application to the analysis of thermal processes in semiconductor laser diode arrays are presented.
