Abstract: Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof. Additional apparatus, systems, and methods are disclosed.

Abstract: A thermal detecting device for sensing temperature at multiple locations proximate to the detecting device is provided. The detecting device has a pair of infrared detectors each configured to measure temperature of two locations by receiving infrared energy of the two locations. A housing encloses the pair of infrared detectors. The housing is configured with an aperture to allow the infrared energy of the two locations to be received by the pair of infrared detectors. A reflective mirror or two mirrors focus the infrared energy of the two locations towards the pair of infrared detectors. The detecting device may be configured to determine if there is a temperature differential at a location as the housing moves with respect to the location.

Abstract: An optical designator system employs a remote source of electromagnetic energy, such as a small hand-held infrared LED or the like, to generate an identifying beam which is directed to the same faceplate through which a displayed image is viewed. A diffuser medium is disposed at the image plane along the rear surface of the faceplate and scatters the incident beam of electromagnetic energy toward orthogonal pairs of photodetectors located adjacent to the edges of the faceplate. The output signals from the photodetectors are presented to a normalizer circuit which compensates for intensity variations of the source of electromagnetic energy into the faceplate. Therefore, the output signal from each normalizer circuit varies in a relationship which is proportional to the distance between the photodetectors at which the incident beam strikes the diffuser medium. The remote energy source is preferably modulated with a waveform which is discernible both from background ambient light and that of the displayed image. Optical and electrical filters associated with the photodetectors insure that normalizer circuits respond only to electromagnetic energy from the remote source.
