A projector capable of making images that elude the capture capabilities of traditional cameras could, when paired with a monochrome sensor array and sophisticated programming, enable 3D spectroscopy on the fly. On its own, the compact Hyperspectral Stripe Projector (HSP) that Rice University researchers have engineered supports a new method for collecting the spatial and spectral information necessary for self-driving cars, machine vision applications, corrosion detection, and more.
In real time, the HSP delivers 4D information from an image — three spatial and one spectral. Whereas one can currently acquire that information using multiple modulators and bright light sources, using their new projector, the Rice University…READ MORE
