A line-scan three-dimensional sensing system measures the surface profile of an object. In the system, a dispersive optical module (DOM) performs forward optical processing to disperse a polychromatic linear light beam into a gradient narrow-band linear light beam (CNLLB) and focus the CNLLB on different focal planes to form a rainbow light pattern to illuminate a scanned surface of the object. The illuminated object displays an informative band color image (IBCI) containing height information of the scanned surface. The DOM captures the IBCI and performs backward optical processing to optically recombine the captured IBCI to form an elongated light pattern. The backward optical processing is the inverse of the forward processing. A slit spatially filters the elongated light pattern to form an output light ray. By analyzing the spectral content of each point on the output light ray, the height profile of the scanned surface can be obtained.
