Abstract. New materials and technologies currently used in the development of new optoelectronic instrumentation and devices are considered. Examples of developments of adaptive optical devices and "structureless" telescopes mounted without rod systems of mutual attachment, implementation of diffraction optical elements, and application of optics based on Fresnel lenses are presented. The design of a telescope of a fundamentally new layout is described, which will be one or two orders of magnitude more compact and cheaper than traditional telescopes. The new layout is a flat panel consisting of a layer of microlenses and arrays of optoelectronic integrated circuits in the board under the lenses for controlling the system, obtaining spectral and spatial information, and image processing.

Keywords: optical materials, technologies, optoelectronic devices, Fresnel lenses, diffractive optical elements, microlenses, microwave photonics, adaptive optics
