Do you know how to make a laser pointer?

With the integration of science and technology in modern teaching, teaching efficiency is improving rapidly. Teachers can walk off the podium and teach in front of the blackboard. Multimedia teaching method is the formation of laser beam or electronic pen. This electronic pen is a tool used to mark laser points in multimedia. However, in the current technology, the form of laser is easy to generate laser points, but it is not perfect, and wireless control is recognized. The traditional form of laser point in the demonstration only includes reflective surface and effective illumination index. The current working principle is to manufacture laser tentacles to realize wireless control.

The laser pen controller transmits the coordinates to the computer receiving part through the built-in laser pen module and projects the coordinates onto the computer screen. The laser pen includes the shell and top, and the control switch and battery box will be installed on the battery box. The selected people live in all one ring, which improves the efficiency. The microprocessor is also installed in the housing. Select the microprocessor to connect independently with the specified laser, control the switch and send signals. The patent mode of utility technologies provides wireless, traditional laser control and knot laser. It can identify the wireless control function for teachers to use. It has two page flipping, buttons on the laser pointer and close buttons. The laser pen has agent mode and switching editing mode.


The front end of the laser pen is provided with a switch sensor for color change. The design of the Laser pointer is also equipped with a module sensor and a control corrector to check the connection between the laser pen and the screen. The laser pen is installed on the side, and the button is replaced with white. The ultrasonic transmitter is installed in the lower left corner and lower right corner of the projection screen, and placed in the lower left corner and lower right corner of the projection screen respectively. They are left main and right main. The screen projection is a coordinate plane, the basic unit on the left is the starting point on the coordinate surface of the projection screen, the laser pointer is generated in the ultrasonic motion unit, and the triangular patterns of the left base and the left base are located anywhere on the projection screen. Generally, the signal of the mobile phone is divided into a certain frequency. The mobile phone is divided into basic units and basic units. The basic units are divided into several basic units. The time is extracted from the calculation of the laser pointer. Finally, through the controller, I convert the laser pointer into the projection coordinate system. Finally, the principle of laser pen is obtained, mainly using mathematical computer technology.
