An infrared laser pointer type remote pointing and virtual touch system, which is characterized in that the system consists of a computer system, an infrared laser pointer, an image acquisition device and an image recognition positioning module; the computer system includes a display device and a host computer. The infrared green laser pointer is equipped with an infrared laser emission key, which can emit infrared laser to point to the display; the image acquisition device is set in front of the display device, and the display is completely contained in the viewfinder; the image recognition positioning module recognizes the infrared laser point and its display According to the position on the screen, according to the acquired image, different operations are distinguished according to the length of time and infrared frequency, including light point indication, light point movement and clicking laser, and control the computer system to generate a light point at the corresponding position of the display screen and complete the corresponding operate. The laser diode and the collimating optics are put together with a plastic bracket to form a laser diode assembly. Most laser diode components have a metal spring on the back. The spring is in contact with the battery in the laser diode and is part of the circuit that draws power from the battery.
Semiconductor manufacturers use highly controlled processes that have been developed in laboratories and then transferred to manufacturing facilities. high powered laser diodes are tested to ensure that they will work properly after manufacturing. Every other component is also tested to ensure that it is working properly. Most manufacturing plants randomly test their products and use statistical control methods to provide quality products. Laser pointers in the range of 1 mW and 5 mW are the only legally permitted laser pointers. Any laser above this value is too powerful and can cause eye and skin irritation. For those who like to show off their beams but don't want to burn things If you like to burn things, and occasionally show off the beam, I recommend 1.6W 445nm laser. Burning things up close is great. For those who like to burn things at a long distance, I recommend a 500MW 405nm laser, which is definitely good for easily igniting matches within 10 meters.
