防紅外偽裝網(wǎng)的防紅外偵測原理是什么？

What is the principle of anti infrared detection for anti infrared camouflage nets?

　　主動式紅外線報警器由發(fā)射機和接收機兩部分構(gòu)成。

The active infrared alarm consists of a transmitter and a receiver.

　　其中，發(fā)射機包括電源、發(fā)光源、光學(xué)系統(tǒng)等組成部分，在電源的作用下，紅外發(fā)光二極管發(fā)射紅外光束，經(jīng)光學(xué)系統(tǒng)作用變成平行光發(fā)射出去。

Among them, the transmitter consists of components such as a power supply, a light source, and an optical system. Under the action of the power supply, the infrared light-emitting diode emits an infrared beam, which is then converted into parallel light and emitted by the optical system.

　　接收機包括光學(xué)系統(tǒng)，放大器，光學(xué)傳感器，信號處理器等組成部分。 負(fù)責(zé)接收發(fā)射機發(fā)射出的紅外線，并經(jīng)光電傳感器將光信號轉(zhuǎn)換成電信號，經(jīng)信號處理器分析處理后傳給報警控制器。

The receiver consists of optical systems, amplifiers, optical sensors, signal processors, and other components. Responsible for receiving infrared radiation emitted by the transmitter, converting optical signals into electrical signals through photoelectric sensors, and transmitting them to the alarm controller after analysis and processing by the signal processor.

　　主動式紅外線報警器就是利用發(fā)射機發(fā)射紅外線，而接收機接收紅外線來工作的。在發(fā)射機與接收機之間形成了一條紅外警戒線，在正常情況下，發(fā)射機發(fā)射紅外線。

An active infrared alarm is a device that uses a transmitter to emit infrared radiation, while a receiver receives infrared radiation to operate. An infrared warning line is formed between the transmitter and receiver, and under normal circumstances, the transmitter emits infrared radiation.
