METHOD AND DEVICE FOR AUTOMATIC ADJUSTMENT OF MIRROR TELESCOPES Russian patent published in 2019 - IPC G01B11/27 

FIELD: measurement.

SUBSTANCE: invention relates to control and measurement equipment and can be used for automatic adjustment of two-mirror axial telescopes during operation. According to the first version, the device for automatic adjustment of the mirror telescope consisting of main 1 and secondary 2 mirrors has measuring module 3 and a control element. Control element is control mirror located in alignment and stationary with main telescope mirror 1 of mirror 1, fixed in zone of central opening of main mirror 1 and representing Mangin mirror, in which first in direction of beams surface 5 has dielectric selective coating, and second on direction of beams surface of control mirror 6 has mirror reflecting coating. Device comprises measuring module 3, consisting of two parallel point monochromatic radiation sources 7 and 8 of different spectral ranges λ₁ and λ₂, behind each of which there arranged in series are collimator lens 9 (10) and auxiliary optical elements: mirror 11; mixing plate 12; beam-splitting plate 13, by means of which optical radiation is introduced on optical axis of telescope, and matrix photodetector 14. Measuring module 3 additionally includes interfacing lens 15 and microlens raster 16. Micro-lens raster 16 together with matrix photodetector 14 forms Shak-Hartmann type wave-type sensor 17.

EFFECT: invention provides on-line monitoring and stabilization of optical parameters of alignment of telescopes during operation under unfavourable factors, including temperature, mechanical, power and wind loads.
