The study describes scanning space-based assets which, by means of a flat scanning mirror and an optical system, provides the transformation of the object space into a temporal sequence of electronic signals of a photodetector with a time delay and charge accumulation. High accuracy of photodetector elements polling and scanning of the object space is due to the movement of the scanning mirror according to the indications of a non-contact interferometric angle sensor. The reciprocating rotary scanning by a flat mirror is kinetically compensated by the opposite motion of the flywheel, which minimizes residual perturbations on the space platform. To reduce the impulse energy consumption and the time of reversal between the scanning mirror and the compensating flywheel, magnetic reversal energy recuperators are used.

Measured Profile

A multiple probes scanning system comprised of two displacement sensors and one angle sensor is studied for ultra-precise profile measurement. The least squares method is applied to reconstruct the measured profile with uncertainty estimation. The parameters that influence the uncertainty associated with the measured profile are investigated. In order to obtain the optimized uncertainty, the determination of the relative parameters has been discussed in two cases. The first one is that how to select suitable sensors when intervals between two displacement sensors are known. The second one is that how to select suitable intervals between two displacement sensors when the specifications of the sensors are known. The processes of the selection in two cases are illustrated respectively according to the actual situations of the measurement.
