green laser pointer is warmly welcomed in the oversea market

For the 635nm laser diode light source, using ZEMAX software simulation of the imaging lens alignment system aberrations, select the best design. We will try our best to provide the more competitive price for led flash light.
Short pulse laser ranging for error analysis, the use of single-chip control TDC-GP2 chip in a measurement period for multiple measurements, and then calculating the average of the output single-chip, greatly improving the accuracy of pulsed laser ranging. Laser range finder has a simple structure, high repetition rate, high efficiency, light weight, portable, high precision, in the short-range has obvious advantages. Not only fast and accurate measurement of distance used to calculate area and volume, and more convenient, safe and reliable. Is widely used in construction, surveying and mapping industry and other fields. In pulsed laser ranging system widely used YAG laser as a light source, flashlamp-pumped its way mainly into energy, the energy conversion efficiency is low, low repetition rate issue has been difficult to overcome.  green laser pointer is warmly welcomed in the oversea market.
Semiconductor laser ranging system research began in military applications, with the technology, its applications have been increasing [1]. For example, mapping, shipping, sports, car crash and other fields. In the military, the required distance system should have light weight, small size, high reliability, for example, infantry and artillery reconnaissance using hand-held laser range finder, edge detection and edge-to-air control of dual-use laser rangefinder , sniper rifle on the target device, etc.,
But it also has some shortcomings, the relatively long wavelength emission of electromagnetic waves, early radar beam is wider, lower spatial resolution, only applies to the monotonous background of target detection, but also susceptible to interference and attacks with serious shortcomings. 1960s appeared laser technology has greatly promoted the scientific, technical, economic and social development. Laser because of its good directivity, monochromaticity, high brightness, and soon to be used in distance. Although only a band with the radar compared to the change, but it has greatly expanded its ranging capability, such as accurately measuring the distance from Earth to the Moon.
