摘要： Systems for generating uniform monochromatic electromagnetic radiation that include an electromagnetic radiation source and a bandpass filter assembly to filter electromagnetic radiation emitted by the electromagnetic radiation source. The systems also include an optical integrating sphere to receive the filtered electromagnetic radiation and to uniformly scatter the filtered electromagnetic radiation within the optical integrating sphere, wherein the optical integrating sphere comprises an output to emit the uniformly scattered, filtered electromagnetic radiation.

摘要： A laser-based target detection system applicable for search-and-rescue type operations takes into account a plurality of optical attributes in the energy delivered to, and received from, a target-containing area so as to enhance effectiveness. In addition to analyzing the returned optical signature for sufficient energy reflected by a potential target at a primary laser wavelength, the system also senses the target's effect on a supplemental optical attribute, and only when sufficient amplitude at the primary wavelength is detected in conjunction with a substantial effect on the supplemental optical attribute is a valid target confirmed. In one embodiment, the supplemental optical attribute is amplitude at a wavelength other than the primary wavelength, with the system preferably looking for a high degree of attenuation at the non-primary wavelength. In an alternative embodiment, polarization is used as the supplemental optical attribute, with the system preferably looking for change of orientation in the return optical signature.
