  • HYPERSPECTRAL IMAGE BASED ON DUAL-FREQUENCY COMB
    Publication number: 20220364923
    Abstract: A method for generating a illumination dual-comb signal that provides a low frequency train of interferograms (180) readable by a regular video-rate camera (160) comprising N pixels and a sampling frequency of V Hz to extract hyperspectral information (170), the method comprising providing a monochromatic signal, splitting the monochromatic signal in two split monochromatic signals, frequency shifting each monochromatic signal with an offset frequency below V 2 ? Hz , generating two frequency combs having a difference in repetition below V 2 ? Hz by a nonlinear modulation of the two split monochromatic signals, generate the illumination dual-comb signal, Illuminating a target and employing a video-rate camera (160) to read a low frequency train of interferograms (180) based on a reflected and/or transmitted signal of the illumination dual-comb signal and performing Fourier transformation of the low frequency train of interferograms (180) detected by each pixel from the N pixels to ex

  • Road condition sensor and method for detecting the state condition of the roadway
    Patent number: 11433903
    Abstract: Sensor and method for detecting road conditions while a vehicle is moving, the sensor comprising a dual optical frequency comb, optical means for directing the output beam of the comb towards a verification site of the road, a photodetector and receiving optics for directing the back reflected light towards the photodetector, the photodetector being provided with electronics for obtaining the RF spectrum of the detected signal and resolving the optical spectrum of the verification region from the RF spectrum.
