Production of laser pointer can be smoothly and timely performed

Production of laser pointer can be smoothly and timely performed.
At this point, century community first laser was born. Laser has monochromatic, coherent, and a series of excellent features. Since its birth, it is predicted that its bright future. Over the years, manufacturing output a variety of different wavelengths of laser, and even tunable lasers. The successful development of high power laser, but also opened up new areas. Free-electron laser in 1977, the mechanism is completely different, its substance is the free electron with high energy, people can expect to achieve a continuous high-power output of this laser, and cover the frequency range to the direction of the length of two developments.
The clock circuit motor driver module servo drive module reset circuit power supply module 4.1 composition of the block diagram of the control system hardware design 5.1 motor drive module 12 based on laser detection of smart car power transistor to control the DC motor as a power amplifier output. Simple circuit structure and principles of the linear driver the ability to accelerate, Darlington H-bridge circuit. SCM Darlington to make it work in the switching state of the duty cycle is adjustable, precise adjustment of motor speed. This circuit in the saturation of the pipe cut-off mode, the efficiency is very high, H-shaped bridge circuit to ensure the speed and direction control. The supply management of laser pointer should be done strictly.The laser beam light of laser pointer can be seen very clearly
Commercial single priority encoder encoding input is at most 8-way, to constitute a more road priority encoder 6 8-3 priority encoder can be used to expand 40-6 priority encoder device. 4.3.1 The encoding circuit shown in Figure 9, Hangzhou University of Electronic Science and Technology graduate design the 4-640-6 priority encoder circuit diagram 4.3.2 Circuit Theory (1) the priority encoder (74HC148) 8-3 Line Priority Encoder menu 3-7. Eight input lines to be encoded I 7 ~ I 0 8 take one yards, logic 0 is valid, the encoded output A2 A1 A0 with the anti-code. It can be seen that the encoder input is 0 the highest priority encoder, and low if the input is meaningless. The supply management of laser pointer is included in the procedure.
The laser seeker is divided into two parts of the laser receiver and control module; warhead is a general-purpose bombs; also using cluster bombs; the tail is to increase the lift and extend the range. The basic principle is: of the laser-guided seeker head is equipped with the optical system and four-quadrant light detector elements, to receive the laser energy reflected by the target, the angle of parallax between the output characterization of the target line of sight and the direction of guided bombs speed signal to the formation of guided instruction , transmission to the steering gear, turn the corresponding control surface, resulting in control, in order to fix the flight trajectory.
