 Quality of some laser pointer should be improved.
Pulsed laser ranging and radar ranging principle is similar to a laser rangefinder to the target signal, hit the target will be reflected back, due to the propagation velocity of light is known, so long as the optical signal recorded round-trip time, with the speed of light (30 million km / s) multiplied by the round-trip time of the half, that is, the distance to be measured. Now widely used in handheld and portable range finder, the role of number of meters up to tens of kilometers away from the measurement accuracy of five meters. China developed high-precision range finder for satellite ranging measurement accuracy can reach a few centimeters. Continuous-wave phase-shift laser rangefinder is a continuous modulation of the laser beam irradiation test target, resulting from the measurement beam from the phase change, can be converted to a measured target distance. The technical standard of laser pointer is important and necessary to laser pointer .
To ensure accuracy, generally installed on the test target laser reflector. It measures the relative error is one in a million. Laser range finder combined with microwave radar, laser wave velocity can also play a narrow specialty, make microwave radar work by the low elevation of the lack of ground disturbance. Laser ranging and optical theodolites, infrared and television tracking system combined to form the optical tracking system, both as a range test of measuring equipment, but also commonly used as a weapon of optical fire control system. Establish a remote wireless digital communications networks, remote data acquisition, data analysis and monitoring functions, and use of our strong technical support team to provide customers with services such as diagnostics, software upgrades and specialized custom. II laser gas analyzer installed that is, check the manual This manual contains installation, operation and maintenance of the laser gas analyzer, EEx p version (ATEX certification) of Also include a description of the laser gas analyzer and its basic characteristics. Please read carefully before using the laser gas analyzer parts III and IV. It is a state-of-the-art precision instruments, and run the state contains a large number of electronic and laser technology. Installation and maintenance of the instrument to be careful and prepared. Power Supply Unit 100-240V AC to 24V DC. Power supply box through the Ex-p control system connected to the transmitter box. From outside the gas temperature / pressure sensors on the 4-20 mA input signal is connected to the firing unit inside the terminal. Emission unit and receiver unit with a cable connection. From the photodetector to detect the absorption signal is enhanced, and transported to the firing unit through the cable. This is also a power supply cable. Al transmitter box that contains the main part of the electronic unit.This greatly reduces the requirements of the cleanliness of optical components and optical adjustment.Please note the following procedures need to consider the Ex-p control system.
