The laser ranging telescope structure and performance

Laser ranging sensor laser ranging telescope. The laser ranging telescope structure and performance. The wireless RF technology is used for  laser pointer .The wireless presenter laser pointer  owns black screen function
The laser sensor has been widely used in various aspects of the defense, manufacturing, medical and non-electric measurement of the laser sensor is in its own unique advantages to radiate vitality, This paper briefly introduces the principle and application of the laser ranging sensor. The brief introduction of the brief and the advantages of laser sensors laser sensor and its advantages brief and its laser sensor is the use of laser technology to measure the sensor. It consists of laser, laser detector and measuring circuit. The laser sensor is a new measuring instrument, and its advantage is to achieve non-contact distance measurement speed, high accuracy, large measuring range, resistance to light, electrical interference ability. The remote control distance of laser pointer  is no less than 15 meters.
Important features: the laser has four important features. High directivity (ie, high directivity, the speed of light divergence angle is small), the laser beam in an extended range of a few kilometers away, but a few centimeters; high color than ordinary light 10 times more than the width of the frequency of the laser; high brightness, the use of laser The beam convergence can produce up to several million degrees of temperature. Coherence, the two beams overlap, resulting in light and dark to understand the fringes (monochromatic) or colored stripes (natural light) phenomenon is called interference of light. Only the same frequency and direction of vibration, phase equal or week difference between the two constant beam of light that has coherence. Applications - the use of laser with high directivity, high color and high brightness, and other characteristics can be contact-free long-distance measurement.Ie: where: L - measuring sites A and B, between two points distance; c - the speed of light propagation in the atmosphere; t - light from the A, B, once the time required. To measure the A, B, distance to measure the light propagation time t, according to different methods of measuring time, the laser range finder is usually divided into two kinds of phase and pulse measurements in the form of the above equation.
