SCANNING MIRROR PROGRAMMABLE TWO-AXIS DRIVE CONSTRUCTION VARIANTS
Perspective variants of constructing a programmable two-axis scanning mirror drive (SMD) for advanced SC television spectroradiometers - high resolution electromechanical scanners with adaptable parameters - are considered in the article. Three variants of SMD configuration having different optical and kinematic arrangement minimizing the mirror mass properties and overall dimensions, as well as geometrical distortion of raster image scanning, and ensuring high angular sensitivity (<0,05 arcsec) of the scanning mirror (collimating ray) position control with application of interferometric measuring devices within the angular range of no less than ±15 circular degrees at scanning mirror overall dimensions of up to 430×800mm and scanning frequency of up to 1Hz are discussed in the article
