Abstract
A detector having a field of view in elevation on the order of one hundred eighty degrees in one plane and three hundred sixty degrees in a perpendicular plane includes a generally hemispherical lens in combination with an optical frustum. The combination directs incident radiant energy within the field of view onto a centrally located sensor.
Claims24
1-21. (canceled)
A simulation system comprising:
- a plurality of detectors of incident radiation having wavelengths in a range of 200 nanometers to 15,000 nanometers, each of the detectors exhibits a field of view in elevation on the order of one hundred eighty degrees;
- and
- a plurality of weapon mounted, moveable sources of beams of radiant energy with wavelengths in the range.
25-39. (canceled)
A method of simulation comprising:
- emitting at least one beam of radiant energy having a wavelength in a range of 200 nanometers to 15,000 nanometers from at least one weapons-mounted, movable light source;
- and
- detecting at least one location local incident radiant energy emitted from a displaced light source in the range in a field of view in elevation on the order of one hundred eighty degrees.
A simulation system comprising:
- a plurality of means for detecting incident radiant energy having wavelengths in a range of 200 nanometers to 15,000 nanometers, each of the detecting means exhibiting a field of view in elevation on the order of one hundred eighty degrees;
- and
- a plurality of means for emitting beams of radiant energy with wavelengths in the range.
A simulation system comprising:
- means for producing a field of view in elevation on the order of one hundred eighty degrees;
- means for directing incident radiant energy from any angle onto a sensing element;
- means for converting incident radiant energy to electrical signals;
- means for sensing electrical signals converted from incident radiant energy;
A method of collecting incoming incident radiant energy from a field of view on the order of one hundred eighty degrees comprising:
- directing incident radiant energy by a substantially hemispheric lens onto a detector element coupled to a mounting surface;
- converting incident radiant energy to electrical signals;
- and
- sensing electrical signals converted from incident radiant energy.
A method of determining the direction from which incident radiant energy contacts a lens comprising:
- directing incident radiant energy by the lens onto an area of a multi-element detector;
- recognizing the incident radiant energy as contacting the lens from a particular direction from the area of the detector in which the radiant energy is directed.
