Gun is used to measure the speed of bullet flight instruments, generally used to measure the muzzle velocity can be adjusted according to the amount of hand-loaded sub-munitions, ballistic data calculation. Use the light sensor group (keyscreens) placed in the firing position in front of about 2.5 to 4 meters, so when the bullet shooting through the optical sensor group. As the distance between the fixed sensor (typically 2 feet), the microcomputer on the gun bullet through the optical sensor according to the time between, calculate the bullet speed, print or display. Radar is the application of the principle of Doppler effect, the mobile objects on the received electromagnetic waves have the effect of frequency shift, the radar gun is based on the received reflected wave frequency shift calculated, the amount of movement of the measured object speed. As basic as the rays of the laser beam, relative to the estimated speed from the radar effective distance can be measured outside the 1000M; speed, high precision, error <1 km; view of the principle of laser velocimetry, laser beam must be aimed at the vertical and plane ... href="http://www.green-laser-pointer.org/--50mw-laser-pointer-green-laser-pointer_c34.html">50mW green laser pointer beam reflection point, and because the tested vehicle is too far away, and is on the move, or the body is not flat, which led police officers on duty working great strength, it is fatigue. The U.S. company has produced laser technology with continuous auto-speed function of the laser gun, designed to solve this problem. Dongcheng, Dongguan City traffic police brigade to use this improved gun capture speeding vehicles, has achieved remarkable results. The company is making every effort to produce the advanced green laser pointer.

External dimensions: parallel plane of the DUT measurement, such as gauge blocks. Spherical surface of the DUT measurement, such as the ball. Cylindrical surface of the DUT measurement, such as the cylinder diameter. Internal Dimensions: parallel plane of the DUT measurement, such as card board aperture measurements, such as ring. Thread: internal and external pitch diameter measurement. More measurements: horizontal projection optical meter tube to buy (or visual horizontal optical meter tube) and the size of the hook can be measured to compare activity measurement. Measuring range: direct measurement (mm): 0 ~ 100, comparing the measured (mm); 0 ~ 500 (outside dimensions), internal dimensions: using size measurement hook depths from 4 ~ 50 mm, when, 10 ~ 200 mm, using the electric eye measurement device (mm): 1 ~ 20, when measured outside the pitch diameter to 180 mm, inner pitch diameter measuring depth of 10 ~ 50 mm at: 14 ~ 2 × (70 - wall thickness) mm. for vehicles, speed of moving objects is to use laser gun to the principle of laser ranging. 100mW green laser pointer ranging (ie, electromagnetic waves, the speed of 300,000 km / sec), the object is measured by a laser beam, and receives the reflected wave of the laser beam to record the time difference, to determine the measured object and the distance between test points . Laser speed is twice the measured object has a specific time interval of the laser rangefinder, made in the one period of the measured object distance, resulting in the measured object's speed. The company is developing 200mW green Laser Pointer based on the new technology.
