This kind of green laser pointer is widely used by many customers.
For example, the electrically calibrated pyroelectric power meter, the measurement error is less than l + O. Than in the past has greatly improved. Microprocessor for laser measuring instruments, computing and control, expanding the instrument's functions, simplifying the structure of the instrument, and to improve the accuracy of the instrument. Such equipment can not only complete more than one parameter, the meeting also reflected laser science and technology in China in recent years significant progress. Some foreign scholars on China to attract so many scholars to participate in the meeting and the meetings organized so well, but also expressed its appreciation for taste. Fast and accurate laser measurement technology. Surface of a flexible and compact laser-based measurement systems, high-speed measurement and inspection of critical dimensions.In this case, the manufacturer has not enough time to inspect every green laser pointer
In more general situations, the laser micrometer produced by Mitutoyo (MIT) Corp. confirmed in a continuous process speed and accuracy of the laser measurement methods. These systems the laser beam at a rotating mirror. When the rotation of the mirror, the laser beam is fired at a photoelectric cell. The output of the unit with the reach of its beam on the amount proportional to the size change, so that the diameter of the workpiece in the system can be determined in the unit and laser. Commonly used MTI laser micrometer, such as Series544, for a diameter of 1 ~ 51mm workpiece, a precision of about ± 0.0030mm, repeat accuracy of about ± 0.00013mm. Line measurement, the user still have to pay attention to cleanliness and roughness of the parts.
Wuhan University Professor Li Qingquan developed a ground-based laser scanning system, but not yet integrated with positioning and orientation system, mainly used for accumulation of measurement. The country there is no high-precision INS system, and reliable laser scanning DME, the domestic is still not mature airborne laser scanning system. Lidar system composition and classification of laser altimeter, GPS positioning device, the IMU inertial measurement, large relative to color digital camera and hyper-spectral shaping cameras constitute the Lidar system. The system can keep pace with the geomorphology of digital data collection and digital cameras work. GPS and IMU is used to high precision to determine the latitude and longitude of the digital camera and laser radar.  green laser pointer is to highlight the content of the presentation, meeting and discussion.
