Abstract:

Issues concerning the design of on-board laser communication systems are considered. The problems of ensuring minimum weight and size parameters while maintaining the required level of optical quality are deemed principal. Examples of engineering solutions for the formation of the transmission channels of communication systems are demonstrated. Specifics of designing mirror and lens systems for space applications, related to the initial optical quality of telescopes and their defocusing occurring owing to thermal deformation of the structure and variation in the refractive index (during the transition from air to vacuum), are considered.

Keywords:

mirror and lens transmitting telescopes, laser communication systems, optical quality, open channel distance radiation transmission, optical system defocusing, thermal distortion of constructions
