More Information
Summary:An optical sensor comprises foreoptics configured to receive an image signal, an image optic operable to focus the image signal, at least one focal plane array (FPA) configured to detect the image signal, and a jitter stabilization system. The jitter stabilization system can comprise a transmitter configured to transmit a jitter source signal to the foreoptics and a position sensor configured to receive a jitter return signal. The position sensor can be positioned at a shared focus with the at least one FPA. The optical sensor further comprises a diffraction grating operable to reflect and diffract at least a portion of the jitter source signal. The jitter return signal received at the position sensor comprises at least a portion of the reflected and diffracted jitter source signal.
