Measurement of the U.S.S. Monitor Propeller Using Structured Light and Coherent Laser Radar Scanning Technologies

چکیده
This presentation and technical paper describes the scanning and processing of data for the recovered propeller of the United States Navy Warship U.S.S. Monitor. The propeller, designed by inventor John Ericsson, was recovered by NOAA in 1998, conserved over the next six years, and is now on display at The Mariners’ Museum in Newport News, Virginia, where it was scanned in place. Two different measurement technologies were employed to meet the goal of high accuracy and high resolution. The Coherent Laser Radar system was used to scan the overall propeller surfaces at a resolution of 3 millimeters. A Structured Light Scanner was then employed to scan at resolutions down to 12 microns to capture details such as surface features and graffiti etched on one of the blades. The point clouds were then merged to generate an accurate model for dimensional and hydrodynamic analysis. This presentation provides detail and highlights of the scanning and data analysis activity.

متن کاملISICL: In situ coherent lidar for particle detection in semiconductor-processing equipment.
A scanning coherent lidar (laser radar) for detecting and mapping isolated submicrometer particles in hostile or inaccessible regions such as plasma chambers, ovens, tanks, and pipes is described. The sensor uses a noise-canceled diode laser homodyne interferometer of novel design that is insensitive to misalignment, runs at the quantum limit, and requires just one access window. At a false-cou...
متن کاملAltitude measurement using laser beam reflected from water surface
In this paper altitude measurement from water surface using laser beam is presented. Research data indicate that the reflection of infrared waves from water surface is about zero and it is less than 2% for visible radiations. Phase-shift and heterodyne technique was used for the measurement, and the laser beam ( mW p nm 10 , 700 = = l ) was modulated by a sine wave having a fixed frequency....
متن کاملSignal-to-noise ratio in squeezed-light laser radar.
The formalism for computing the signal-to-noise ratio (SNR) for laser radar is reviewed and applied to the tasks of target detection, direction finding, and phase-change estimation with squeezed light. The SNR for heterodyne detection of coherent light using a squeezed local oscillator is lower than that obtained using a coherent local oscillator. This is true for target detection, for phase es...
