The light sensor may include a light emitting sensor having an array of individual light emitters, or a light detecting sensor having a light detector. The control structure may include an array of secondary bi-telecentric lenses for use with the light emitting sensor, or a plate having an aperture extending therethrough for use with the light detecting sensor.

Abstract: A method of estimating non-linearity in a response of an optical detector comprises emitting optical radiation at different intensities. The method includes, at each intensity: amplitude modulating the emitted optical radiation at a modulating frequency to produce amplitude modulated optical radiation; detecting the amplitude modulated optical radiation with the optical detector to produce a detected waveform; and generating a Fourier transform of the detected waveform that includes a fundamental frequency equal to the modulating frequency and harmonics thereof. The method further includes estimating the non-linearity in the response of the optical detector based on a change in an amplitude of a second harmonic of the fundamental frequency relative to an amplitude of the fundamental frequency across the Fourier transforms corresponding to the different intensities.

Abstract: A sensor that is responsive to at least two distinct spectral bands, e.g., infrared radiation and ultraviolet or infrared and visible light makes use of the junction of a diode-based bolometer as a photocell in addition to its temperature dependence for detecting infrared radiation. More specifically the diode bolometer is arranged to work in the conventional manner, in that an electrical characteristic of the diode, e.g., the temperature dependence of its current-voltage (I-V) curve, is used as the basis for measuring temperature, and hence, infrared radiation. Additionally, the same diode may be operated as a photocell to detect radiation that is capable of interacting with the electrons in the junction of the diode. This may be achieved by detecting a change in the operating point of the diode based given its present biasing in response to noninfrared radiation incident upon the diode.
