Definition and Function of laser rangefinder
Laser rangefinders are sophisticated optoelectronic devices designed to measure the distance between two objects. Their construction primarily consists of three systems: optical, electronic, and mechanical. The optical system includes a collimating lens for emission and a focusing lens for reception. The electronic system comprises a pulse circuit that provides high peak current narrow pulses, a receiving circuit to identify return signals, and an FPGA controller for triggering pulses and calculating distances. The mechanical system encompasses the housing of the laser rangefinder, ensuring the concentricity and spacing of the optical system.
Application Areas of LRF
Laser rangefinders have found extensive applications across various industries. They are pivotal in distance measurement, autonomous vehicles, defense sectors, scientific exploration, and outdoor sports. Their versatility and precision make them indispensable tools in these fields.
Military Applications:
The evolution of laser technology in the military can be traced back to the Cold War era, led by superpowers like the USA, USSR, and China. Military applications include laser rangefinders, ground and aerial target designators, precision-guided munition systems, non-lethal anti-personnel systems, systems designed to disrupt the optoelectronics of military vehicles, and strategic and tactical anti-aircraft and missile defense systems.
Space and Defense Applications:
The origins of laser scanning date back to the 1950s, initially used in space and defense. These applications have shaped the development of sensors and information processing technologies, including those used in planetary rovers, space shuttles, robots, and land vehicles for relative navigation in hostile environments like space and war zones.
Architecture and Internal Measurement:
The use of laser scanning technology in architecture and internal measurement is rapidly growing. It enables the generation of point clouds to create three-dimensional models representing terrain features, structural dimensions, and spatial relationships. The application of laser and ultrasonic rangefinders in scanning buildings with complex architectural features, internal gardens, multiple protrusions, and special windows and door layouts has been extensively studied.
