The US Navy has awarded Optra Inc. a $300,000 Phase II Small Business Innovation Research grant to produce an open-path particle analyzer based on laser scattering for use with gas turbine engines. The Topsfield, Mass., company will use an algorithmic technique to extract the particulate size distribution and concentration from the measured scatter pattern. The system is designed to monitor particulate matter downstream from the augmenter tube in the Navy's T-10 test cell. Intended to replace an Environmental Protection Agency method, the approach performs rapidly in a noncontact...Read full articleRelated content from Photonics MediaArticlesCoherent Names Deputy CTO, Appoints VP: People in the News: 07/12/23Coherent Corp. named Young-Kai Chen deputy chief technology officer, and appointed Paul Silverstein vice president for investor relations and corporate communications.
