Paper Abstract

Autocollimation measurement devices have very wide applications in produce of instrument, machine and metrical technology. They are used for ensuring status of details, units and planes, for the control of optical details and straightforwardness directing, and for the control of the displacement of revolving converters, in the national standard planar angle. Autocollimation methods have different errors in the most status. The main systematic error in autocollimation measurement methods is an error caused by vignetting. The analytic research of function describing this error was made. The survey considers vignetting in autocollimation systems and algorithmic methods of errors’ compensation caused by vignetting; also it's considered construction principles of the program model using computer simulation.
