Abstract
Disclosed are apparatus and methods for generating an electronic signal responsive to selected wavelengths of the optical spectrum. An optical thickness differential between two or more photoconductors is used to generate an electronic signal calibrated to be representative of light signals of a selected range of wavelengths.

Apparatus for generating an electronic signal in response to selected wavelengths of light comprising:
- a first photodiode for converting at least the selected wavelengths of light to a corresponding first electronic signal;
- a second photodiode for converting at least additional wavelengths of light to a corresponding second electronic signal;
- and
- a circuit for manipulating the first and second electronic signals to generate an output signal in response to the selected wavelengths of light.
Apparatus for generating an electronic signal in response to selected wavelengths of light comprising:
- a first sensor for converting at least the selected wavelengths of light to a corresponding first electronic signal;
- a second sensor for converting at least additional wavelengths of light to a corresponding second electronic signal;
- wherein the first and second sensors are provided with a spectral sensitivity differential;
- and
- a circuit for manipulating the first and second electronic signals to generate an output signal in response to the selected wavelengths of light.
A method of generating an electronic signal corresponding to selected wavelengths of light, the method comprising the steps of:
- converting at least first and second wavelength ranges of light into first and second electronic signals wherein at least one of the wavelength ranges includes the selected wavelengths;
- and
- manipulating the first and second electronic signals to generate an output signal corresponding to the selected wavelengths of light.
