It is the level of phone jammer the customer asks or needs.
Of foreign laser scanning technology Research 2.2.1 Research foreign airborne laser scanning system in a foreign country, laser technology is the research focus, and has made a lot of results and commercial products, especially the airborne system is gradually maturing. Airborne laser scanning system is mainly used for quick access to a large area of terrain data, developed the TopEye system developed by the Swedish SAAB Canada Optech ALTM system, the United States, John Chance, Fli-Map system and other foreign universities and research institutions to carry out research in this area, for example, the University of Calgary, Canada in 1998 airborne laser scanning system integrated with the experiment. By some professional and accurate adjustment and commission of phone jammer .Whether mobile phone jammer  is worthy being bought by them
An airborne laser scanning three-dimensional data acquisition system through the integration of the laser scanner, GPS and data communication equipment, and a certain scale experiments to obtain the desired results; surveying department of the Netherlands since 1988, began to engage in the use of laser measurement techniques to extract topographic information. 2.2.2 foreign ground-based laser scanning system Research, airborne laser scanning system products and applications have become more mature, and ground systems products and applications is still in the stage of development, the integration of ground-based laser scanning technology (especially mobile systems) is an international research focus. University of Tokyo, Japan, in 1998 the ground fixed laser scanning system integration and test, and achieved good results. The commission process of mobile phone jammer  is complicated.
Design of various circuits, the use of MCU product diameter calculation, measurement and display the results. Target. Knowledge and understanding of the photoelectric detection technology. Learning and application programming software. Research to understand the status of the photoelectric detection system, the requirements for the subject, given the overall design, the laser line measured from both hardware and software design diameter instrument. Design. The measuring principle, the commonly used two non-contact measurement method, a received optical signal measurement method based on the CCD device, the other is the laser scanning method. Both methods have their advantages and disadvantages, let's take a look at their works. To check whether the revise and improvement of phone jammer can be performed.
