title: [Use of gas laser LG-55 to determine the optical density of biological objects].
abstract: In order to registrate optic density of such subjects as vessels, tissues, roentgenogram and electrophoregram images, a universal device is suggested. It consists of a) a gas laser lg-55 supplying a parallel bundle of light with small angular deflection and wave length of 0,6328 mc; b) mounting for attachment the reversive motor pd-9 with transmission to change the speed of the subject table, photo resistance fCK-1, focussing lens triple-edged prism and diaphragm, c) double coordinative recorder (endim 620.01). Repeatedly performed registration of the same arterioroentgenogram (or any other investigated) has demonstrated a high accuracy of the registered curves.
