The inspector issued the qualification report for laser pointer

 ATMEGA16 high-performance low price on the product application market has a strong competitive edge, by many household appliances and equipment manufacturers and instrumentation industry, fancy, so that the ATMEGA16 to enter the high volume of applications [13]. ATMEGA16 is a based on AVR RISC, low-power CMOS 16-bit microcontrollers, because in one clock cycle to execute a command, ATMEGA16 can achieve performance close to 1MIPSMHZ. The weekly report of laser pointer  should include the manufacturing status of laser pointer  .VirtualBench software such as NI's analytical instruments to have a lot of features, it can plug into a oscilloscope data acquisition card and dynamic signal analyzers. With the great development of social productive forces, modernize the production requirements of electronic equipment varieties, features high accuracy, high degree of automation, and requires testing speed, real-time, with a good user interface. Virtual instrument just to meet these requirements. Compared with traditional instruments, several virtual machines with the following advantages. The manufacture procedure of laser pointer  specifies the manufacturing requirements of laser pointer. The design uses the company's S5973-02 Hamamatsu photodetector.  The inspector issued the qualification report for laser pointer.laser pointer   is a kind of modern information tool
Clinical application of laser in surgery after years of practice, has achieved a relatively mature and rich experience.
Commonly divided into light and heat energy detection method and optical method. Photothermal method to thermopile or pyroelectric sensor material pieces absorption detector, which allows the full effect of laser and absorber, and then absorbed by the body's thermal sensor test temperature, resulting in the value of the heat absorber, the laser energy value. Photoelectric method to photoelectric detectors or semiconductor photodiode as sensing devices for photoelectric detectors, optical signals into electrical signals, the signals received by the charge integrator with the input optical pulse energy is proportional to the voltage signal, thus completing the energy measurement. As the photodiode measurement dynamic range, measurement speed, to reflect changes in the envelope of the signal, cheap, is widely used in optical signal detection. The fault status of laser pointer  should be supervised from time to time.
Therefore, the system selected PIN photodiode photodetector. Photodiode is a PN junction using one-way conductive junction photoelectric conversion device information. Photosensitive diode is reverse biased when the general purpose of adding a PN junction in the direction of the electric field in the same direction of the external electric field, so that a linear photodiode characteristics and frequency characteristics will completely change the good, the output photocurrent light intensity only by weak impact of changes, regardless of the size and load resistance. Photodiode size, high sensitivity, good stability, fast response, easy access to orientation, spectral response in the visible region and infrared region [8]. Considering the above advantages, this design uses a photosensitive two laser measuring laser emission intensity, some lasers which have been packaged in a photodiode.
