The laser protection design of green laser pointer resists the current surge so as to make a long lifetime.GPS is a measurement technique, the principle is According to the satellite sends the signal to calculate a time with three or more satellites the distance, in order to estimate the location of the now generally two types of laser positioning, one is airborne laser scanning, one is the ground-based laser scanning machine set of generally equipped with GPS and inertial navigation systems used to obtain a moment of the aircraft position and angle with an accuracy of 0.3m, a high degree of accuracy of 0.15 meters. the ground is a fixed point in a scan, range of tens of meters to a few hundred meters, precision 15mm to 1m in about (according to the different scanning range) laser positioning collimator for large equipment installation, maintenance, testing and research and design of dedicated high-precision reference measuring instruments. The green laser pointer supports the browsing of all formats of demonstrating files and websites.The optical system design in science the spatial phase modulator, in the long-distance measurement ...
... spot is a ring-gate structure, the spot of the image is clear, so that the whole measurement process without focus, without focus to achieve a full run worse, in order to ensure the host is provided by the laser beam a high-resolution, easy to distinguish between the laser beam of laser light collimator positioning target (with magnetic base) can be adsorbed on the object to be tested, so that users complete the testing, processing, installation and other needs. the beginning of its development for the military-industrial complex , missile targeting, and positioning devices, laser rangefinder (200mW green Laser Pointer distance measuring) is a laser as the light source distance, according to the way work is divided into continuous laser lasers and pulsed lasers.The green laser pointer is guaranteed for 1 year. helium-neon, argon, krypton gas laser operating in cadmium Continuous output state for phase-shift laser rangefinder; double heterostructure GaAs semiconductor laser for infrared distance; ruby, neodymium glass solid-state lasers for pulsed laser rangefinder, laser range finder due to the laser color is good, strong directional features, coupled with the semiconductor-based integrated electronic circuits, optical rangefinder, compared with not only day and night operations, but also improve the range accuracy, a significant reduction in weight and power consumption, the measured artificial earth satellite, the moon and so far target distance into reality. 50mW green laser pointer rangefinder - method of laser ranging method commonly used laser range finder to measure distance in two ways: phase-pulse method and the method of pulse ranging process of law is so : The emitted laser rangefinder was measured by the reflection object then was to receive rangefinder, green laser pointer range finder while recording from the time the product of the speed of light and the half round-trip time is the range finder and the object being measured the distance between the distance measurement accuracy of the pulse is generally within + / - 1 meter.The so-called 2.4GHz of green laser pointer refers to a working frequency band, which is between 2.405GHz and 2.485GHz (science, medicine, agriculture). In addition, the measurement of such range finder blind is usually about 15 meters, laser range finder. Overview of the laser laser range finder laser range finder is the use of accurate determination of the distance from the target (also known as laser ranging) instruments. The laser protection design of green laser pointer

Laser ranging is used to locate, is launching a laser signal, according to the received signal reflected back from objects in the time difference to calculate the distance, and then to determine the launch angle of the laser transmitter and the angle of the object, so as to arrive object and the relative position of the transmitter and then the 100mW green laser pointer scanner according to their position (usually with a GPS positioning or location of a user-defined coordinates), we can determine the location of the object.
