Visible laser equipment for many-to-many communication with high sensitivity and anti-interference that can assist in positioning

Abstract

The invention belongs to the technical field of laser communication, and specifically relates to a high-sensitivity and anti-interference multi-to-many communication visible laser equipment that can assist positioning, including a signal modulation and emission device and a signal reception and demodulation device. The signal modulation and emission device is used for For emitting visible laser signals, the signal receiving and demodulating device is used to receive the visible laser signals emitted by the signal modulating and transmitting device. The invention can solve the problems in the prior art that the transmission of optical signals is easily interfered, and the combination of multiple signals affects the sensitivity and accuracy of equipment.

Description

technical field [0001] The invention belongs to the technical field of laser communication, and in particular relates to a high-sensitivity and anti-interference multi-to-multi-communication visible laser device which can assist positioning. Background technique [0002] In the existing laser equipment used for live CS games, the transmitting device uses infrared light as the signal, and the signal is coded (ASK, FSK, PPM, PWM modulation mode) to be emitted by the transmitter, and then received by the corresponding receiving device , to realize the transmission of information. [0003] Since the device uses infrared light, which is invisible to the naked eye, it is impossible to transmit optical signals and assist aiming at the same time. Therefore, an additional laser aiming device needs to be added for actual game combat, which will cause problems such as complex structure of the device and high manufacturing cost. In addition, infrared light is invisible to the naked eye...
