The manufacture can customize this kind of green laser pointer

m sequence of laser range finder has a lot of the advantages of a continuous wave radar, can take advantage of the transmitter power, the use of the correlation detection and coherent accumulation of signal processing to improve signal processing gain to improve anti-jamming capability of the laser ranging radar and ranging accuracy, The point of the interpolation algorithm used in the m sequence ranging laser radar to improve ranging accuracy. Theoretical analysis of the pulsed laser range finder, ranging error. The laser has a good direction, good color and high brightness features, the laser ranging and optical ranging, high precision, fast, far advantages. In recent years, the national production and equipment at Force tanks, guns, guns, antiaircraft guns and fire control system, laser rangefinder has more than 170 species, and has formed a standardization and serialization of products. The output power of  green laser pointer is in accordance with their own requirement and need.
In addition to military applications, geodesy, construction of national economic construction and the measurement of the spatial objectives has also been widely applied. Pulsed laser range finder principle. Pulse ranging principle of the laser range finder is shown below. Targeted by the laser transmitter to transmit a laser pulse echo pulse reflected from the target back, and then received by the receiving system, by measuring the pulse round-trip time t in the test distance, known as the speed of light c, is available (1) obtain the test target distance S: S = ct / 2 (1) a very short time t, must be used to produce the standard time scale of the fixed frequency oscillator and electronic counter to record. If the time scale oscillator frequency is f. The manufacture can customize this kind of green laser pointer  for the better use of the customer.
Back and forth between the rangefinder and target time t (ie the time interval between the sampling signal and the echo signal). Contains the time scale pulse number is n, then the test distance S as follows: where c and f are known, as long as the measured n, can be obtained by (2) a brief analysis of the test from S. ranging error . The laser rangefinder ranging accuracy is mainly dependent on the counter count accuracy and instrument ranging error. Count accuracy is determined by reference oscillation frequency counter, that is, the reference oscillator frequency must, then count accuracy is a given value. Ranging error refers to the display the results of the rangefinder and the difference of the actual distance. The main factors affecting the ranging error: the influence of the crystal oscillator frequency stability B. The laser beam light can also be customized for this kind of  green laser pointer .
C. laser pulse width of the receiving system response time. In short, when measuring the same distant targets using a single pulse laser rangefinder rangefinder ranging error. LIDAR application in mobile robots. Distance measurement is the essential technology of the mobile robot. At present, the mobile robot is widely used in laser ranging radar (hereinafter referred to as LRS Laser the Range Sensor) for three-dimensional ranging, mainly for the following reasons. As a sources ranging means, compared to the LRS Ranging Passive Ranging with complex image matching technology and less influenced by the ambient light. Three different kinds of colors of  green laser pointer can be customized for the customer.
In the active range finder, LRS ranging accuracy is relatively high, directional specular reflection is small and made low. Direct access to distance ranging method, ultrasonic, shortwave and laser modulation wave three kinds of wave source ultrasonic directional difference between the specular reflection is serious and can be measured shorter distances, the shortwave ranging accuracy is less than the cost of the laser modulation wave and ultrashort wave radar is also higher, compared to the laser modulation wave and other wave source has the following advantages: high strength, very useful for measurement of long-range goals and objectives and background of the distinction between a narrow beam good parallel, scattering, which guarantees a good range direction resolution are generally single-frequency light waves, spectral pure This ensures a high signal to noise ratio.   laser pointer   includes the red laser beam light, blue laser beam light and green laser beam light.
