Nominal voltage of laser pointer is 3.7V DC

Nominal voltage of  laser pointer  is 3.7V DC.
To better used in combination, should be effective to switch can be selected ranging method according to their needs, ranging This method of calculating the telescope control IC TM0610 for both phase method, but also the method of calculation of the pulse method, and in the telescope to add buttons to select the measurement method through this button to select the judge should use which The calculation of the measurement method, to achieve our different needs on different occasions. Chassis key point laser scanning system is a combination of measurement based on laser scanning and characteristics of the target system, which can be measured on the three-dimensional size of the bottom of the vehicle location point.  laser pointer  has a safety pigtail.
Non-contact measurement system in this topic, simple structure, large measurement range, strong anti-jamming, high-speed, high accuracy and other advantages of the size of the three-dimensional coordinates real-time multi-point measurement. This paper studies how to improve the system accuracy and stability, measured by the four beams, and gathering information processing, this study content, including: in-depth analysis of the system measurement principle, the analysis of four-beam measuring principle, the target logo and directional reflection principle. According to the mathematical model and system architecture to achieve the four-beam platform to build, optimize machine performance. Brushless DC motor performance in the research system, the stability of the motor speed-related factors. Steady speed precision based on the speed loop and current loop control based on motor performance. There is a universal obstacle that how teachers can integrate modern teaching facilities including laser pointer  into their classroom teaching context.The disadvantage is that the low accuracy can only measure the surface relief is small compared to flat objects, for objects with relatively large surface relief, often on steep at the phase mutation, so that the measurement accuracy greatly reduced. Demodulation distortion grating hatched Fourier analysis and phase-shift method. Fourier analysis of the phase shift method easier to ten automated, but the accuracy is slightly lower. Closely integrated stereo vision measurement method is the continuous progress of optoelectronics, camera and computer technology to produce passive stereo vision measurement, its principle is the same point of the surface imaging point position difference exists in the left and right images, according to the location of the point of left and right images imaging you can calculate the spatial coordinates of the object corresponding points.  laser pointer  can be widely used in teaching institutions.
This approach is more relaxed, to adapt to wide, high efficiency, highly computerized, especially when measured from the surface reflectance characteristics, it is widely used in robot vision applications require aerial mapping, defense technology and industrial automation monitoring.
