A cube-corner is employed as a photoelectric autocollimator's reflector to extend the angle
measurement range and the corresponding algorithms are deduced. Experimental …

Autocollimators (ACs) are primarily used for two-dimension measurement with small angle.
A three-dimensional AC (3D-AC) with a large measurement range and capable of 3D angle …

Although autocollimators enable noncontact measurement, their performance is limited in
large-scale and long-distance applications because of errors caused by nonideal point light …

In order to suppress the effect of the temperature variation on the wavefront of the laser
communication terminal, the secondary mirror support with flexure hinges is designed. The …

The fast steering mirror (FSM) is a key element in electro-optical systems. For designed fast
steering mirror driven by voice coil motors, considering the plant parameter uncertainty due …
