A laser-based imaging system can now create high-definition 3-D maps remotely, with the ranging accuracy made possible by frequency combs. A team at the National Institute of Standards and Technology demonstrated the imaging system, which can create the 3-D surface maps from as far away as 10.5 m. Using lidar, the new system is also sensitive enough to detect weak reflected light. The frequency combs were previously demonstrated at NIST, but are now being used to continuously calibrate the laser imaging system. The system operates on a principle similar to optical coherence...Read full articleRelated content from Photonics MediaARTICLESOptomechanical Accelerometer Enhances AccuracyA laser light-powered accelerometer — a sensor that detects sudden changes in velocity — operates over a greater range of frequencies than comparable, nonoptical instruments, and at a...Photonics Spectra May 2021 IssueHybrid Approach Enables Ultralow-Loss Integrated Photonics for LidarResearchers at École Polytechnique Fédérale de Lausanne (EPFL) and Purdue University demonstrated a hybrid approach to on-chip acousto-optic modulation by combining piezoelectric...Vision Spectra Autumn 2020 IssueFishbone Waveguide Design Flattens Dispersion, Expands Bandwidth of Frequency CombsA waveguide design that could enable highly precise frequency combs has been created by a research team from the French Centre National de la Recherche Scientifique, Paris-Saclay University, and...Photonics.com 7/28/2020Applications for Portable Optical Gas Analyzer Range from Volcanos to SewersHamamatsu Photonics and the National Institute of Advanced Industrial Science and Technology (AIST) in Tokyo collaborated on an all-optical, portable gas monitoring system for predicting volcanic...Photonics Spectra November 2021 IssuePRODUCTSLaser Detection and Ranging SystemThe DYNAMIC 9D laser detection and ranging (LADAR) system from Automated Precision Europe GmbH provides noncontact optical dimensional metrology for manufacturing uses.
