An improved imaging light detection and ranging (lidar) system is presented which provides variable time delay range gating across a selected image. Variable time delay range gating across an image is accomplished using a plurality of imaging cameras which are individually triggered after preselected delays to obtain multiple subimages. These multiple subimages are then put together in a mosaic in a computer to provide a complete image of a target plane using only one light pulse.

An apparatus for detecting and imaging an object enveloped by a backscattering medium which is at least partially transmitting to light comprising: generating means for selectively generating short pulses of light; projecting means for projecting said short pulses of light toward the backscattering

An apparatus for detecting and imaging an object enveloped by a backscattering medium which is at least partially transmitting to light comprising: generating means for selectively generating short pulses of light; projecting means for projecting said short pulses of light toward the backscattering medium and at an object enveloped by the medium; detecting means for detecting said pulses of light reflected back from said object after a time delay corresponding to the round-trip propagation time of said light pulses to and from said object; and converting means for converting said detected pulses of light to a video image of said object; wherein said detecting means further comprises; a plurality of cameras directed laterally across a target image, each of said cameras obtaining a subimage of said target image; time delay generator means for selectively gating each of said cameras after a predetermined time delay to produce variable time delay gating across said target image viewed by said cameras.
