Sentence examples for deviation of the mirror from inspiring English sources
Three laser displacement sensors produced by Keyence Corporation are used for measuring the surface deviation of the mirror for feedback shape control, and three PVDF patches are laminated to the nonreflective side of the mirror to serve as actuators for surface shape control.
