Abstract
An optoelectronic module operable to acquire distance data and spectral data includes an array of demodulation pixels and an array of spectral filters. The demodulation pixels can possess an intrinsic wavelength-dependent sensitivity, wherein the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing micro-lens array in some cases. In some cases, the intrinsic wavelength-dependent sensitivity can be offset by a combined filter array, while in other cases the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing filter array. Still in other cases, the demodulation pixels can be operable in such as to offset the intrinsic wavelength-dependent sensitivity.
