A New Design of Laser Phase-shift Range Finder Independent of Environmental Conditions and Thermal Drift
This paper presents a technique to improve the performance of laser phase-shift range finders. The phase measurement is performed by using a new method to extract the phase-shift data from the peak of received and transmitted intermediate frequency signal amplitudes. The pulse width modulation is used to minimize the noise effect and enhance the signal amplitude measurement. The advantages of p...
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 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 کاملIncoherent pulse compression in laser range finder
Laser ranging measurements using incoherent pulse compression of complementary code pairs is reported. The two bipolar codes are converted to unipolar representations using a pulse position modulation algorithm, and used in succession in intensity modulation of a laser ranging source. Reflected echoes from a wall target are directly and incoherently detected. The cross-correlation between each ...
