A laser scanner to meet all the requirements. Question 5: What are the manufacturers production time - poor flight 3D laser scanner manufacturers? Question 7: What is the emission frequency of the pulsed laser? The emission frequency of the pulsed laser, namely the PRR (Pulse Repetition Rate) pulse repetition frequency. It expresses the number of the laser pulse is emitted in the laser per second or Hertz. Because the laser is stimulated emission of light, so, the PRR is not a constant, a change in amplitude. As we say: the laser pulse emission frequency is 5,000 Hz, it may sometimes fired 4,950 Hz, and sometimes fired 5,010 Hz.  laser pointer  should be recorded in the related document as the log and reference.
Typically, the laser scanner vehicle and airborne laser scanner using a 2D laser scanner, and sometimes, in-car system also used a 3D laser scanner. Whether a 2D or a 3D laser scanner, are one-dimensional laser scanner (or rangefinder) through the motor rotation and / or prism movement production. The higher the transmission frequency of the laser pulse, the greater the number of laser point cloud emitted per unit time. In general, in order to achieve the highest accuracy when scanning, we have to choose the equipment of the highest laser emission frequency and the smallest increment point of view, scanning laser point cloud density reaches the maximum value of the equipment. Equipment from different manufacturers, the emission frequency of the laser pulse PRR. It is vital in improving the quality of  laser pointer 
From Tempo, Optech, Leica ScanStation 1, the i-site, 2,000 -5,000 Hz to 27,000 Hz Riegl's LMSZ-Z-series. In general, the higher the transmission frequency of the laser pulse, the smaller the angle of the laser scanning increment, the shorter the time required to complete a panoramic (360 degree horizontal) high-precision scanning, that is, the faster the scanning speed. Therefore, we choose a laser scanner to pick PRR parameters in order to improve work efficiency. At the same time, we must choose the parameters of high angular resolution. Therefore, some manufacturers will also PRR known as the laser scanning speed, such as the Leica company. Riegl LMS-Z series 3D laser scanners laser pulse emission frequency of 27,000 Hz. The better production way of laser pointer  is selected.
