Design And Implementation Of A Laser Treatment Control System

The traditional treatment of the body surface lesions is surgical excision, it is easy toleave scars or hurt the adjacent healthy skins. Currently laser has been widely used inmedical cosmetology. Laser treatment can produce laser which can be absorbed by bodysurface, then organization will generate an effective treatment and target will be removed.It is more safe and effective to use laser in medical cosmetology. Laser medical is boundto be a popular part of medical cosmetology.Computer is participate in the whole operation as the existing laser treatment must becontrolled by computer, which is a waste of computer resources. Not only does it reducethe stability of system, but also increase the size and the cost of laser treatment device.Nowadays it is a trend that laser treatment becomes smaller and lighter. The thesis takesVisualDSP++as the development environment to design and implement the controlsystem of carbon dioxide laser treatment based on BF533. At first we do an analysis ofsystem needs and propose the overall design of the system. By dividing the system intosome modules, we details the design philosophy for the key modules：interpolation, filling,calibration and interaction module. The algorithms are optimized, too. Then we achievethe data-saving module, data-reading module, cooling water testing module, DACoutputting and laser working module to achieve the function of the system. Finally, wesummarize the advantages and the disadvantages of the system, discuss the points that thesystem needs to improve and the next phase of work.Through the system testing in the latter part of development and the customers’feedback, we find that the system has reached the customers’ needs. As the control systemseparates from computer, the laser treatment gets more stable and smaller. It costs less, too.We can find that the control system is absolutely reasonable and practicable through itsperformance in the practice.
