Recently, a number of hyperspectral cameras with novel image sensors that are equipped with a monolithic pixel-by-pixel filter array have been introduced onto the market. In this contribution, we describe the design and implementation of a structured light 3D sensor consisting of two such snapshot mosaic sensors, each with 25 different spectral bands between 600 and 975 nm, and a broadband GOBO projector that images varying, aperiodic sinusoidal patterns into the measurement volume. We characterize the system with regard to accuracy, and we present measurements of different objects illustrating the benefits of hyperspectral 3D sensors.
