It is the standardized use of green laser pointer

 In all, the customer should pay much attention to the use and safety of green laser pointer .
Control of single chip multiple measurements in a measurement period of TDC-GP2, and then through the single-chip computing the mean value output, greatly improving the accuracy of a pulsed laser ranging. The laser rangefinder has a simple structure, high repetition rate, high efficiency, light weight, portable, high precision, there are obvious advantages in the short-range aspects. Not only can accurately be used to measure distances, calculate area and volume, and more convenient, safe and reliable. Is widely used in the field of construction engineering, surveying and mapping industry. Commonly used in pulsed laser ranging system YAG laser as a light source, due mainly flash pump to inject energy. green laser pointer should be used in the suitable occasion in the appropriate way.
Therefore, the energy conversion efficiency, low repetition rate has been difficult to overcome. Semiconductor laser ranging system based on semiconductor lasers as light sources, semiconductor lasers based on electricity directly injected in the form of work, has the advantages of high optical conversion efficiency and high repetition rate is currently subject to the attention of domestic and international research institutions, and launched a in-depth study. However, the semiconductor laser rangefinder there are still some deficiencies, low energy output and systematic errors to some extent, limit the application of laser ranging. Therefore, how to improve performance is the pressing problem of the semiconductor laser ranging system to solve the problem, there are two means, first, to improve the laser output power, the second is to improve the performance of the receiving system. It is the standardized use of green laser pointer .
Mainly discussed in this article is to improve the the collimator ability to launch system to make the output power is more concentrated, and reduce the error in the system to the receiving system and the results more accurate. Subject of the meaning and origin. The semiconductor laser ranging system began in the military applications, with the development of the technology and its applications continue to expand [1].
