NASA has selected a Luna Innovations-built semiconductor laser for use in its Navigation Doppler LiDAR system. “To precisely measure the vehicle speed, direction, and distance, our NDL system uses both Doppler shift and laser beam travel time, which requires a highly stable single-frequency laser source,” said Farzin Amzajerdian, NDL principal investigator from NASA Langley Research Center. “The RIO laser from Luna Innovations has met NASA’s requirements for high reliability, low noise, and ultra-narrow linewidth.”
