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 method and apparatus for aligning optical components within an optical sensor. A mask with an elongate slot formed therethrough is placed optically between an optical emitter and an optical detector of the sensor. The mask is rotated 180 degrees while the detector output is measured. As the mask is rotated, the output varies. The longitudinal position of the slot that corresponds with the maximum detector output is indicative of the transverse direction that the optical emitter must be moved relative to the optical detector for optimal alignment. A controller may operate a first actuator for translating the optical emitter with respect to the optical detector and a second actuator for rotating the mask, thereby automating the alignment process.
