Claim 6:
7. The method of claim 1, wherein the first lens (L3) and the second lens (L2) comprise an imaging lens, wherein the DMD is a 2-D DMD configured to translate in sub-micromirror distances along the x and y directions and wherein the camera module further comprises a 2-D folded spectrum optical dispersion optic (D3) positioned in front of the DMD, such that when the incident light comprises multi-wavelength collimated light, the method further comprises:
producing by the 2-D folded spectrum optical dispersion optic (D3) a 2-D folded spectrum irradiance distribution in the x-y dimensions from the incident light prior to mapping onto the image plane of the DMD.
