A Compressive Ultrahigh-speed Continuous Imager Using Spectrally-structured Ultrafast Laser Pulses

Case ID:

C13352

This invention uses chirped processing and electro-optic modulation in optical fiber components to encode unique pseudorandom binary patterns at an ultra-high rate onto the spectra of broadband mode-locked laser pulses. Each laser pulse receives a unique spectral pattern and then serves as an ultrashort burst of structured illumination of an object inside a 1- or 2-D spatial disperser. The output energy of each pulse after striking the object is recorded with a photodetector and digitizer and an image is reconstructed using Compressed Sensing recovery from only a few percent of the number of samples required for conventional Nyquist sampling.
