  • High-speed imaging using periodic optically modulated detection
    Patent number: 11960100
    Abstract: Methods and systems for imaging a target. In some examples, a system includes an optical modulator configured for applying, at each time of an exposure window, a respective optical modulation pattern to a received image of the target to output a modulated image. The system includes a camera configured for capturing a single image frame for the exposure window by receiving, at each of time, the modulated image of the target. The system includes a demodulator implemented on a computer system and configured for demodulating the single image frame based on the optical modulation patterns to recover a number of recovered image frames each depicting the target at a respective recovered time within the exposure window.
