Experimental results or new approach to the problem oI sharpness runct ion maximization in adaptive optics are presented. The main dirre.. rence rrom ordinary method is in rorming of signals, proportional to the components or sharpness runction gradient, in optical proces sor. This solution is very errective in case or low light intensity, when the quantum errects of registration are essential. It is shown that in particular case the scheme or adaptive system is similar to curvature sensing system. Experimen tal system provides 32—zonal correction or wave front in real atmospheric conditions for objects of various forms. Subject terms: adczpttve opttcs; deformabLe mtr rors; shc1rpness funct ton; phase dtstort tons.
