Pulsed Time-of-flight Laser Range Finder Techniques for Fast, High Precision Measurement Applications
This thesis describes the development of high bandwidth (~1 GHz) TOF (time-of-flight) laser range finder techniques for industrial measurement applications in the measurement range of zero to a few dozen metres to diffusely reflecting targets. The main goal has been to improve single-shot precision to mm-level in order to shorten the measurement result acquisition time. A TOF laser range finder...
متن کاملUnified Pulsed Laser Range Finder and Velocimeter using Ultra-Fast Time-To-Digital Converter
In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
متن کاملMicro-Laser Range Finder
Laser range finders are a vital component of high precision targeting engagements. The precise and accurate range-to-target information is an essential variable in the fire control solution of today’s sophisticated weapons. This range information is readily provided by the laser range finder, however, current fielded laser range finders are bulky, heavy, difficult to mount onto weapons, eye haz...
متن کاملPIDAR: 3D Laser Range Finder
The Pidar provides 3 dimensional points to a client that represent a 3 dimensional environment. An infrared laser sensor provides distance data along a Z axis and angular data on an x axis. A motor rotates the laser mechanism around a Y axis; this supplies the system with the necessary data in order to create a 3D point cloud representation of an environment. The Pidar utilizes a Linux operatin...
متن کاملProfiling of hot surfaces by pulsed time-of-flight laser range finder techniques.
The possibilities for using the pulsed time-of-flight (TOF) laser radar technique for hot refractory lining measurements are examined, and formulas are presented for calculating the background radiation collected, the achievable signal-to-noise ratio (SNR), and the measurement resolution. An experimental laser radar device is presented based on the use of a laser diode as a transmitter. Results...
