Abstract
An integrated imaging spectrometer for hyperspectral imaging (HSI) system is disclosed. The integrated imaging spectrometer features photonic PLCs that include an array of input channel waveguides, one for each pixel of an image scene. Spectral grating filters are positioned along the length of each waveguide to extract the spectral components as the light propagates to the end of the waveguide. The filters route the optical energy to photodetectors and the detected electrical signals are captured by a read out integrated circuit (ROIC). Together the PLC, detectors, and ROIC form an imaging layer. Stacking imaging layers generates a device capable of recording an entire 3D high-resolution spatial/spectral image data cube in real-time.
