Abstract
Systems, apparatuses and methods may provide for a light collector to capture an inbound optical signal and a plurality of detectors, wherein each detector is associated with a wavelength detection range that differs from one or more wavelength detection ranges associated with one or more remaining detectors in the plurality of detectors. Additionally, a microelectromechanical system (MEMS) device may include a plurality of mirrored columns, wherein each mirrored column is coated with a material that is associated with a wavelength reflection range that differs from one or more wavelength reflection ranges associated with one or more remaining mirrored columns in the plurality of mirrored columns. In one example, the MEMS device positions the plurality of mirrored columns to route the inbound optical signal to one or more of the plurality of detectors based on an input signal from a user input device.
