Can lasers be used to determine the color of an object? lasers can be used to determine shape of objects such as landforms and buildings, so is it possible to calibrate laser light to reflect back only certain colors? For example, a object is painted half black and half red. Would one be able to send laser lights toward the object, ensuring that only the red reflects back while the black absorbs the light? Would this have to be fequency specific (absolute color) or would one be able to measure a range of frequencies (shades of color)? Thanks for your insight!
