Abstract
A multi-function sensor system including an auto-alignment system. The multi-function sensor system includes a laser module configured to provide a transmit beam and an auto-alignment beam, a shared aperture component, a first channel configured to direct the transmit beam and the auto-alignment beam to the shared aperture component, a second channel configured to receive the transmit beam from the shared aperture component and provide a receive beam to the shared aperture component, and a third channel including a passive imager configured to receive the auto-alignment beam and a first portion of the receive beam from the shared aperture component, wherein the auto-alignment beam propagates through the passive imager to provide an indication of a line of sight (LOS) of the transmit beam relative to a field of view (FOV) of the passive imager.
