  • Publication number: 20250130318
    Abstract: Methods and apparatus for optical detection having fast recovery from high amplitude input signals. In embodiments, a LIDAR system includes a photoreceiver to receive a return signal, and a circuit to modulate a gain of the photoreceiver over an acquisition window for the return signal, wherein the acquisition window contains time T0, and wherein the gain at time T0 is at a minimum for the acquisition window. In embodiments, the time T0 is at the beginning of the acquisition window.
