초록 ▼

Detectors and methods for gathering, detecting and analyzing electromagnetic radiation are disclosed. A radiation detector includes one or more positive lenses to direct radiation to mirrors or to a photodetector. Coordinates of directed radiation are measured and interpreted to determine the angle of arrival. A color filter mosaic may be present to determine wavelengths of detected radiation. Temporal characteristics of the radiation may be measured.

1. A radiation detector comprising: (a) a photodetector, and(b) a plurality of lens-mirror assemblies, each lens-mirror assembly comprising a positive lens, a first mirror and a second mirror, the first and second mirrors being adjacent, wherein the lens is disposed to direct radiation from a first range of angles of arrival to the first mirror, radiation from a second range of angles of arrival to the second mirror and radiation from a third range of angles of arrival to the photodetector, the mirrors being disposed to reflect radiation to the photodetector. 2. The radiation detector of claim 1 wherein the lens-mirror assemblies are disposed and configured to direct radiation arriving from across a hemisphere or more to the photodetector. 3. The radiation detector of claim 1 comprising a plurality of photodetectors. 4. The radiation detector of claim 3 wherein the photodetectors form an array of photodetectors. 5. The radiation detector of claim 4 wherein the array of photodetectors is an image sensor. 6. A method for analyzing electromagnetic radiation, comprising: providing the apparatus of claim 4;placing the apparatus in a selected orientation to collect the electromagnetic radiation;measuring the output of the array of photodetectors; andcomparing the measured output of the array to a known output of the array previously determined as a function of azimuth and zenith angles of incident radiation to determine the azimuth and zenith angles of incident radiation with respect to the selected orientation of the apparatus. 7. The method of claim 6 wherein the measured output of the array and the known output of the array previously determined include cluster analyses of selected photodetectors. 8. The method of claim 6 further providing a color filter mosaic operably positioned between the plurality of lens-mirror assemblies and the array of photodetectors and computing signal transmitted through the filter mosaic to determine the wavelength of the electromagnetic radiation. 9. The radiation detector of claim 1 wherein the photodetector is a solar cell. 10. The radiation detector of claim 4 further comprising a color filter mosaic operably positioned between the plurality of lens-mirror assemblies and the array of photodetectors. 11. The radiation detector of claim 10, wherein the color filter mosaic comprises a radiation filter or a radiation up-converter. 12. A method for analyzing radiation detected by the radiation detector of claim 10, comprising: determining a centroid position and a mean radius of at least one distribution of radiation detected by the photodetector,identifying a wavelength of the detected radiation at a distance from the centroid position that is less than or equal to the mean radius. 13. The method of claim 12 further comprising evaluating a photodetector signal for information about one or more of temporal characteristics, angle of arrival, or irradiance of directed radiation. 14.

The radiation detector of claim 1 further comprising a matching assembly disposed between the plurality of lens-mirror assemblies and the photodetector. 21. A method for analyzing radiation detected by a radiation detector of claim 1, comprising: determining a centroid position and a spatial extent of at least one distribution of radiation detected by the photodetector. 22. The method of claim 21 further comprising: comparing the coordinates of the centroid position and the value of the spatial extent with coordinates of a centroid position and value of a spatial extent from a radiation distribution having a known angle of arrival; and identifying the angle of arrival of the directed radiation. 23. The method of claim 22 wherein the centroid position and spatial extent of at least two distributions of radiation detected by the photodetector are determined. 24. A method of converting solar radiation to electricity, comprising: providing a plurality of lens-mirror assemblies, each lens-mirror assembly comprising a positive lens, a first mirror and a second mirror, the first and second mirrors being adjacent, wherein the lens is disposed to direct radiation from a first range of angles of arrival to the first mirror, radiation from a second range of angles of arrival to the second mirror and radiation from a third range of angles of arrival to a solar cell, the mirrors being disposed to reflect radiation to the solar cell; andplacing the plurality of lens-mirror assemblies between the solar cell and the sun whereby electricity is generated.
