Target detection using laser pointer pen, to obtain data and generate accurate digital elevation model. Its working principle is not difficult to understand, is to transmit and receive red laser. in laser pen light, each component contains a transmitting unit and a receiving unit. The transmitting / receiving component and a rotating mirror with together, can scan at least one diode laser.
Send not only most powerful laser reflection mirror diode laser, but also can make the reflected laser beams then reflected to the receiver. By rotating mirror, can achieve 90 to 180 degree angle, and greatly reduce the complexity of the design and manufacturing system, because the military laser is the only movement mechanism.
The detection distance is the principle of light return time based on laser pointer pen red laser by pulsed light, exposure to the target after a portion of the reflected light back, install a laser pen light diode in nearby, it can detect the signal back, by calculating the emission and detection of the time difference can be calculated on the target the distance of.Diode laser once activated can collect a lot of most powerful laser.
But laser beams in extreme weather or the performance of smoke environment is greatly reduced, and because of the large amount of data collection, the price is very expensive. Red laser radar currently installed in military laser and laser pointer pen (unmanned vehicle on the line number, the better the performance, cost more expensive), welcome to come.
