DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its Geiger-Mode Laser Vibrometry Methods & Systems. **Background:** Traditional laser vibrometry is based on coherent detection where the signal of interest is a phase modulation of a carrier. Since the phase change is typically a small fraction of a wave, its amplitude is much lower than the carrier amplitude and as a result system performance is limited by Carrier-to-Noise (CNR) ratios. Direct detection would be better suited to extracting the smallest signals from background noise and the best single-photon level detectors are Geiger Mode Avalanche Photodiodes (GMAPDs). GMAPDs experience a transient dead time after an event detection rendering them unsuitable for this task. **Description:** This invention circumvents the GMAPD deadtime limitation by using an array of GMAPDs in a non-imaging configuration instead of a single element. By using an array, with sufficient number of elements, guarantees there is always at least one element available to detect an incoming photon even if others are in the deadtime zone. **Advantages/Benefits:** Allows direct linear detection of weak signals. Allows remote measurement of vibration signatures on buildings, vehicles and equipment at ranges more than an order of magnitude greater than previously possible. Not limited by low amplitude signals typical of traditional coherent detection. Sensitivity is arbitrarily large limited only by the number of GMAPD array elements. **Potential Applications:** Remote vibration sensing applications in aerospace, defense, automotive, electronics, NDE and the environment. **Development Status:** Current stage of technology development: TRL 2-3 LLNL has patent(s) on this invention. U.S. Patent No. 11,693,117 Geiger-Mode Laser Vibrometry Methods & Systems published 7/4/2023 LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace.
