MULTIPLE BAND PASS BAYER PATTERN FILTER

An apparatus including a pixel array comprising two or more photo-sensor elements; a first optical filter disposed on a first photo-sensor element of the pixel array, the first optical filter configured such that a spectral response of the first optical filter includes: a first passband in a first wavelength range, and a second passband in a second wavelength range, the first passband and the second passband being separated by a first stop band; and a second optical filter disposed on a second photo-sensor element of the pixel array, the second optical filter configured such that a spectral response of the second optical filter includes: a third passband in the first wavelength range, and a fourth passband in the second wavelength range, the third passband and the fourth passband being separated by a second stop band; wherein the second passband and the fourth passband are discrete passbands in an infrared range.
