The invention discloses a method and system for calculating the output power of a semiconductor laser, and the method comprises the following steps: S1, selecting the change modes of the output power of the semiconductor laser according to the requirements of a user, and specifically dividing the change modes into a constant mode and a fluctuating mode; s2, if the change mode of the output power is fluctuation, further acquiring average output power, maximum fluctuation amplitude and fluctuation frequency; if the change mode of the output power is constant, the average output power is further obtained, and meanwhile a maximum fluctuation amplitude value and a maximum fluctuation frequency value are preset; and S3, based on the average output power, the maximum fluctuation amplitude and the fluctuation frequency, determining the change condition and the actual value of the output power according to the change function. According to the invention, diversified light supply modes are provided, and lasers with different light intensities can be emitted by outputting different instantaneous output powers, so that better user demand experience is achieved.
Description
technical field [0001] The invention relates to the field of semiconductor lasers, in particular to a method and system for calculating the output power of a semiconductor laser. Background technique [0002] In recent years, physical therapy instruments that use laser light generated by semiconductor lasers to irradiate the retina to achieve the effect of myopia prevention and control have been more and more widely used. The technical principle of this physical therapy instrument is that light can increase the content of dopamine on the retina, and dopamine can play an important role in retinal development, visual signal conduction and refractive development, etc. Eye axis growth, to achieve the purpose of myopia prevention and control. [0003] On the other hand, it has been shown that dopamine in the retina is mainly secreted and released by amacrine cells and interplexiform cells, while amacrine cells mainly respond to changes in light intensity rather than light intens...
