Patent number: 12566143Abstract: Implementations disclosed describe, among other things, a sample inspection system that includes an illumination subsystem to illuminate a sample with a plurality of time-spaced light pulses generated, using a pulse multiplexing system, from a source light pulse. The pulse multiplexing system includes a plurality of optical loops, each deploying an optical coupler that outputs a first portion of incident light to a sample and provides a second portion of incident light as an input into the next optical loop. The sample inspection system further includes a collection subsystem to collect a portion of light generated upon interaction of the plurality of time-spaced light pulses with the sample, and a light detection subsystem to detect the collected portion of light.Type: GrantFiled: January 10, 2024Date of Patent: March 3, 2026Assignee: Applied Materials Israel Ltd.Inventors: Elad Eizner, Haim Feldman, Boris Golberg, Ron Naftali, Keith Wells
