摘要： A system for landing or docking a mobile platform is enabled by a flash LADAR sensor having an adaptive controller with Automatic Gain Control (AGC). Range gating in the LADAR sensor penetrates through diffuse reflectors. The LADAR sensor adapted for landing/approach comprises a system controller, pulsed laser transmitter, transmit optics, receive optics, a focal plane array of detectors, a readout integrated circuit, camera support electronics and image processor, an image analysis and bias calculation processor, and a detector array bias control circuit. The system is capable of developing a complete 3-D scene from a single point of view.

摘要： A lightweight, inexpensive LADAR sensor incorporating 3-D focal plane arrays is adapted specifically for modular manufacture and rapid field configurability and provisioning. The sensor generates, at high speed, 3-D image maps and object data at short to medium ranges. The techniques and structures described may be used to extend the range of long range systems as well, though the focus is on compact, short to medium range ladar sensors suitable for use in multi-sensor television production systems and 3-D graphics capture and moviemaking. 3-D focal plane arrays are used in a variety of physical configurations to provide useful new capabilities.

摘要： A dual mode ladar system includes a laser transmitter having a wavelength of operation and a modulator connected thereto to impose a modulation thereon. The modulator is configured to impose amplitude modulation and/or frequency modulation. Diffusing optics illuminate a field of view and an array of light sensitive detectors each produce an electrical response signal from a reflected portion of the laser light output.

摘要： A ladar sensor assembly includes a semiconductor laser and a diffusing optic for illuminating a field of view utilizing modulated laser light from the semiconductor laser. A lens is configured to receive the modulated laser light reflected off at least one object. An array of light sensitive detectors are configured to receive the modulated laser light received by the lens. The assembly further includes at least one piezoelectric actuator operatively connected to the lens for dynamically positioning a focal plane of the received modulated laser light on the array of light sensitive detectors.

摘要： A hybrid three dimensional imaging camera comprises a 2-D video camera utilizing a focal plane array visible light detector and a 3-D flash laser radar utilizing an infrared focal plane array detector. The device is capable of capturing a complete 3-D scene from a single point of view. A production system combining multiple hybrid 3-D cameras around a subject provides 3-D solid models of an object or scene in the common field of view.
