The power of green laser pointer is no less than 30mW

The power of green laser pointer  is no less than 30mW
October 17, 1997, the U.S. Army Air Force and Missile Defense Command has used powerful ground-based mid-infrared advanced chemical laser irradiation aging / MST1-30 satellite, the main purpose is to test satellite laser resistance ability. The United States / MST130 satellite was launched in May 1996, the satellite carrying the ordinary telescope in the infrared, near infrared and visual focal plane antenna array is mainly used for observing the Earth, in order to help the design of infrared earth observation satellite, the satellite The service life is over, the experimental observation satellite was hit and carry infrared sensors are not damaged. The experiment continues in the study. As long as the good supply management of  green laser pointer  is implemented.
The system uses a simple MAX232CPE chip. A MAX232CPE chip to be completed by 2-way TTL / CMOS ~~ RS-232 level conversion and 2-way RS-232 to TTL / CMOS, the level conversion. TXD serial output only way the microcontroller in the actual circuit, the RXD serial input. Therefore, the selection of pin 11 by 2051 TXD serial output; corresponding to 14 feet to the computer's serial port input. Figure 4-10 MAX232CPE chip internal structure of Hangzhou University of Electronic Science and Technology graduate design software design 5.1 The general scheme of the system of signal detection and data transmission part, the software part is less involved. The efficient working relationship of  green laser pointer  is asked for.
Synchronization (see Chapter II hardware design part) off target approach, targeting and signal acquisition, transmission, off target and the target is classified as a class processing; data transmission using a UART serial communication. R & D direction and key technologies. Rational division of the photodetector of the laser target, to improve the accuracy of the system; single-pulse amplification and shaping of small-signal; the expansion of multi-channel priority encoder; and PCs for data transfers, facilitate the statistics of the results, save, display and query. The main technical indicators of the laser pulse: shooting distance: serial output frame format: greater than 1ms 30 meters Shots + hit number of photoelectric detectors. Laser pulse response amplitude.
The flexible C language is only a total of 32 keywords, nine kinds of control statements, procedures written in the form of freedom, is case-sensitive. Combine the basic structure of the high-level language and the statements and the practicality of the low-level language. C language like assembly language, bits, bytes and addresses to operate, and these three are the computer the most basic unit of work. Operator rich C language operator contains a very broad range, a total of 34 kinds of operators. C language braces, assignment, and cast and so deal with as operator. So that the operation type of the C language is extremely rich, diversification of expression types, using a variety of operator can be difficult to achieve in other high-level language computing. The after service of  green laser pointer  is the key point.
