Paper Abstract

The two-channel optical circuit for measurement and the control of divergence of laser radiation over the sizes of the prints received in a plane of registration is considered. Analytical expressions for estimation of single and a solid angles and also for definition of divergence sign are presented. Experimental results are submitted. A few advantages are compared with the known circuit of a focal spot.
