摘要： A LIDAR system that can accommodate both a clear atmosphere and be adaptable to environments in which smoke, dust or other particulates (i.e., a degraded environment) exist in the atmosphere around the target is described. The system operates in two fields of regard: clear view mode (wide field of regard) and a degraded view mode (narrow field of regard). The wide field of regard allows the output laser energy to be concentrated over a large number of detector pixels and thus resulting in high scene scan rate. The narrow field of regard allows concentrating the laser output energy on fewer pixels to compensate for the loss of laser energy due to atmospheric degradation. The combination of the ROIC and LIDAR modes of operation result in a system that is capable of operation under clear and degraded environments.

摘要： The ACASS 3D LIDAR system operates in a fundamentally new manner combining features of flash LIDARS and scanning LIDARS simultaneously which enables mission and performance trades to be conducted by varying the sizes of illumination patches within the scenes being observed. Further the combination of these modes of operation into a single LIDAR system enables multiple modes of operation and multiple missions to be accomplished with single lasers obviating the need for multiple lasers and enabling significant simplification of beam control modes. Systems which result from the new, expanded size, weight, power, cost trade space enabled by the ACASS concept can provide new levels of performance at significantly reduced risks and costs The achievement of wide area, three dimensional imaging using a LIDAR sensor system is accomplished with one laser which operates using an eye safe fiber laser with very high puke 13 rates but very low energy per pulse.

摘要： The thermoelectric detector comprises an infrared absorber pixel structure supported by two electrically connected beams made of a thermoelectric material. One end of the thermoelectric beam connects to the infrared absorber pixel structure; the other end connects to the substrate. The detector comprises a microlens for collecting and focusing infrared radiation on the detector. Infrared radiation is incident on the infrared absorber pixel structure results in a temperature gradient along the length of the thermoelectric legs, and generating an electrical voltage proportional to the gradient. A low noise SIGe BiCMOS readout integrated circuit is coupled to the detector to provide a background limited detector having improved detectivity.

摘要： A source produces light, preferably in a wavelength band of approximately 185-200 nm and in pulses at a suitable frequency (e.g., 100 Hz). The light may be directed in a progressively diverging beam into the atmosphere for a Rayleigh scattering by molecules in the atmosphere in the 185-200 nm wavelength band and for fluorescence by particular molecules (e.g. oxygen) in the atmosphere in another wavelength band (e.g. 210-260 nm). The Rayleigh scattered light and the fluorescent light may pass in a progressively converging beam to two detectors, one responsive to the Rayleigh scattered light to produce first signals and the other responsive to the fluorescent light to produce second signals. Optical elements may prevent the second detector from responding to the fluorescent light and the second detector from responding to the scattered Rayleigh light. A data processor processes the first and second signals to provide outputs representative of the atmospheric pressure and temperature. These outputs may have a great accuracy, in part by regulating the characteristics of the light source and the first and second detectors at times between the successive light pulses from the source. The progressively diverging and progressively converging beams may have a focal point displaced externally of the housing by at least a particular distance to avoid effects of turbulence when the housing is in a moving vehicle.
