Multi-matrix opto-electronic system for measuring deformation of the millimeter range radiotelescope elements
A novel optical instrument is proposed and studied to measure the deformation of each connection point for a mirror, which includes 24 multi-matrix base units and can be used in millimeter-scale signal reflection systems. Experimental investigations reveal that the error of measurement is σ =8.7×10...

Experimental investigations reveal that the error of measurement is
