摘要:
According to the invention, an integrated hyperspectral imager includes a planar photonic substrate. A plurality of imaging pixel photonic circuits is disposed in a M×N array on the planar photonic substrate. Each imaging pixel photonic circuit includes an input coupler configured to receive a broadband input electromagnetic radiation. A waveguide is optically coupled to the input coupler. A plurality of wavelength filters is optically coupled to the waveguide. Each wavelength filter has a wavelength filter input and a wavelength filter output. Each detector has a detector input optically coupled respectively to each of the wavelength filter outputs. Each detector has a respective detector output. The integrated hyperspectral imager is configured to provide electrical signals that are representative of a hyperspectral image of the received broadband input electromagnetic radiation. A method for recording an image based on a received electromagnetic radiation is also described.
