Abstract

Disclosed are methods and apparatus for subtractive image detection using interferometric subtractive color imaging. The methods and apparatus employ an electromagnetic wave reflecting device, and at least one photoresponsive detector at either a fixed or variable distance from one another, with a gap in between, that may include a dielectric. The distance is set such that the detector is positioned at one or more zero nodes of standing electromagnetic waves resultant from incident electromagnetic waves reflected by the reflecting device. The zero node of the electromagnetic wave will corresponds to a zero energy point of a particular frequency of the electromagnetic wave. By using interferometric detection, less loss of light may be achieved, and positioning the detector at known zero energy points for known light frequencies, affords subtractive detection, which reduces computational complexity.
