Abstract
A camera includes a pulse transmitter for transmitting at a transmit time through an aperture and along an optical path to a target a coherent electromagnetic ranging pulse at a first wavelength range outside the visible spectrum. In some embodiments, the camera includes a reflected pulse detector for receiving a reflected electromagnetic pulse reflected by the target back along the optical path and through the aperture at a detect time subsequent to the transmit time. In some embodiments, the camera includes a shutter positioned for shielding the pulse detector from at least transmit time to an intermediate time between the transmit time and the detect time. In some embodiments, the shutter includes a layer of semiconductor material placed in the optical path at a point between the target and the detector.
