This article considers a self-alignment system (SAS) designed to measure the mutual angular position of laser beams while designing, operating and adjusting high-precision laser optical-electronic systems (OES). A method of measuring angular misalignment of optical axes of receiving and transmitting system channels with the use of various algorithms of digital signal processing is proposed. Measurement error is analyzed; technique for reducing this error by means of optimization of lens optical system, which is used to perform those measurements, is proposed

The article considers a system of automatic adjustment of high-precision laser devices that are using a powerful mainlaser radiation. This system performs alignment of optical axes of receiving and transmitting channels with additional marker laser. Considered problems arising due to the spread of high-power infrared operating laser close to receiving channel, designed for visible light. A method for study of the influence of diffraction on parameters of radiation of the mainlaser is proposed. The technique of study of influence of thermal blooming on the parameters of radiation of the mainlaser on the basis of approximation of the thin lens is developed.
