Embodiments of the present invention include a beam combiner comprising a planar lightwave circuit having a plurality of surface waveguides arranged to define a plurality of input ports, a mixing region, and an output port. Each input port receives a different wavelength signal and provides it to the mixing region. The mixing region combines the plurality of wavelength signals into a single composite output beam that is scanned over a region to create an image in a region.In some embodiments, the projector (1) interrogates image points in the region using a first wavelength signal to determine a measurand and (2) projects an image over the image points of the region using a second wavelength signal, wherein each image point is illuminated with the second wavelength signal based on a measurand at that image point.
