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.

Optoelectronic modules for the acquisition of spectral and distance data

An imaging device, including a monolithic semiconductor integrated circuit substrate, comprises a focal plane array of pixel cells. Each one of the pixel cells includes a gate overlying a region of the substrate operable to convert incident radiation into charge carriers. The pixel also includes a CMOS readout circuit including at least one output transistor in the substrate. The pixel further includes a charge coupled device section on the substrate adjacent the gate, the charge coupled device section including a sense node to receive charge carriers transferred from the region of the substrate beneath the gate. The sense node is coupled to the output transistor. The pixel also includes a reset switch coupled to the sense node. The pixel's charge coupled device section has a buried channel region. The pixel also includes one or more bias enabling switches operable to enable a bias voltage to be applied to the gate. At least one of the reset switch or the one or more bias enabling switches is formed in the buried channel region.
