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.
