Abstract: A structured light imaging system for measuring coordinates of a surface may include a first imaging lens, a spatial light modulator provided after the first imaging lens, a second imaging lens provided after the spatial light modulator, and an imaging sensor provided after that second imaging light modulator. A method of measuring coordinates of a surface using a structured light imaging system may include illuminating the surface with structured light from a projector and adjusting light intensity at each pixel of the imaging system by using a feedback loop system such that each pixel of the imaging sensor will operate in a linear response range.
