The optical system of the laser beam optical path switching, scanning, the laser beam to produce a variety of effects. Displacement of the control system of the optics of the optical system, turn the drive control. Unit of the light path in front of the optical console, the corner of the control signal from the drive motor and the mirror, the microcontroller to control the motor to drive the mirror incident laser beam will be reflected to the screen to the formation of the pattern. The optical path scanning signal from the graphics file. Through a graphical image processing software to produce graphic contours to be displayed in the production of contour lines to pay attention to the contour of the closed and concise. Display graphic distortion degree remove the contour line of the anchor, the anchor made the more graphics more close to the originals. green laser pointer owns a longer range of 20m.
But file the greater the increase in scan cycle of a graph. Anchor the coordinates (x, y) by D / A conversion output, optical console driver board to control the direction of the reflector, the anchor point is mapped to the screen body. Galvanometer scan frequency, can be done 25 Figure / s laser scanning display quality can be protected. Laser animation show the principle of general animated display similar to an animation file consists of multiple action picture, in order to take the anchor coordinates to locate the scan. The optical path scanning unit is a direct implementation of the entire system to produce graphic effects. 3.1.3 XY working platform optical light guide system console optical path switching mirror changes driven by the motor corner. laser pointer has the elegant surface treatment.
According to the program of pre-programmed microcontroller through the D / A card output switching signal to the splitter unit of the motor driver board, amplified to drive the motor rotation. To the surface of the projection geometry, the key is a combination of both motor speed and direction to achieve the combination of the spatial dynamics of the laser beam. Due to the continuity of light to 4 move in the mirror, inevitable even as a line between two points, so on the screen, projected graphics, graphics divided into a section of straight line segments, as long as the control of reflection mirror to the laser beam at each end between the fast-moving sequence. Innovative design of green laser is according to the ergonomic principles.
For an axis, through the mirror of the optical path analysis, that the X to the motor control of mirror 1 and Y mirror to the motor control to control the direction of the X and Y directions of the projected graphics on the screen. To a square, for example, as shown, to take the center of the square is the origin of coordinates (that is, the optical path of the starting point), the four vertices of the square A, B, C, D,. Projected on the screen like a square, two stepper motor rotation direction and order as follows: the first on-screen projection point to the point E, that is, stepping Y to the motor is transferred to step 3; then X is to the motor to the motor reverse rotation to the rotation in step 3 (point A); Y in step 6 (point B); X to the motor reverse rotation step 6 (C); Y to the motor forward rotation of step 6 (point D); X-to Forward motor rotation in step 3 (E point). green laser pointer is with learning code.
Thus, to get some kind of graphics on the screen, just the graph on the xy plane is divided into a section of straight line segments connected to each other, and then calculate the location of each endpoint, it can be programmed to control the motor. However, due to the limitations of the motor rotation speed, to make the screen projection of graphics is not flashing, the graphics can not be too complicated. Dynamic combination of coordinate Figure 2.1 Figure 3.2 The control circuit 3.2.1 control module as the core of the design of the control, the microcontroller is no doubt played a pivotal role. It to complete the reading of the external graphic data, software programming pulse sequences to control the motor direction and speed, and eventually reach the steering control of the laser light beam pattern graphics. The receiver of usa green laser pointer is of the mini-size.
