So more and more profits of green laser pointer can be got

In addition, the use of single-chip microcomputer system can also further increase the use of LD power function, such as display, timing and timekeeping functions. LD power single-chip microcomputer control system is the use of the United States Microchip Technology's PIC family of microcontrollers PIC16C55. The single-chip RISC, two pipelined command structure and Harvard (Harvard), dual-bus architecture is a cost-effective 8-bit embedded microcontrollers. At the same time, the MCU also has a low operating voltage (the minimum operating voltage of 3V), low power consumption (3V, 32kHz clock operating current is 15μA), the output drive LED capacity and programming convenience features. Its single-chip microcontroller circuit shown in Figure 3. It is the sales plan of  green laser pointer  .
Figure D / A converter DAC0832 and integrated operational release LF356 microcontroller PIC16C55 RB I output digital signal into analog control voltage, so you can directly control the T2 base to adjust the current of the iF. In the boot of the micro-controller system, the first double-throw switch K1, K2, playing to the high side. The RC7 port access to the high, the system software into the preset state by K1, so that the user can set the power supply output current range. Adjust S1 is ~ S4, four buttons can be the output current of the LD power transferred to the desired value. At this point, and then press the S5 confirm button to confirm the current range. But the RC0 mouth of the red indicator light indicates the system into the output waiting state. So more and more profits of green laser pointer   can be got.
And then double-throw switch K1, K2, playing to the low side, so that the green light goes out; RC7, the low, the system output by K; press S6 key, micro-control system to control an LD power from the slow start procedure power supply to the LD laser. At this time, S1 ~ S4, four buttons, adjust LD power output current of the iF, in order to achieve the regulation of the LD laser power. At the same time, S1 ~ S4 also doubles as a working time regulation to control the laser blood therapy time. In addition, the circuit is also arranged for the voice prompt circuit. After the power supply into a stable, if an exception occurs, you can press the the S6 key to make the system software to control an LD power to stop power supply to protect the LD laser. The sales plan of  green laser pointer   is very important for the customer.
Micro-controller system software block diagram shown in Figure 4. The microcontroller LD power and LD laser has successfully designed applications blood therapy instrument ILLLI green, is currently being tested with good results. Expansion of the medical applications of semiconductor laser semiconductor laser because of its wavelength, high power laser array and the fiber guide light and laser energy parameters compatible microcomputer control the emergence and rapid development. Semiconductor lasers are small, light weight, low cost, wavelength selectable, its clinical application covering a range of applications for other types of laser. Mainly used in spectroscopy, interferometry, the detection and diagnosis of clinical specimens or tissue, clinical treatment. It is to improve the sales volume of  green laser pointer  .
Medical monitoring and diagnostic laser is the most successful in the basic medical application provides the most advanced instruments for analysis cytology. There is no doubt that the development of the semiconductor laser miniaturization of laser medical devices will widen the road. 1.1 laser Doppler technology laser Doppler technique has been applied on many occasions, but the instrument has a large volume, the required water-cooled, and prone to interference shortcomings. The introduction of semiconductor laser technology, such as:% frequency stabilization of semiconductor lasers can produce the tachometer when the optical frequency shift F 'G, the use of optical heterodyne techniques can remove the optical frequency shift fluctuations from scattered light signal the Doppler frequency; diode-pumped H4: IJK ring laser by a different refractive index and the length of the fiber velocimetry optical frequency shift within the required range, and the quadrature signal to identify the flow. It is to take up market shares of   laser pointer  .
