  • Laser Radar
    Laser Radar
    Lidar (Laser Radar) is a radar system that emits a laser beam to detect the position and speed of a target. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, you can obtain relevant information about the target, suc...

  • OCT imaging technology
    OCT imaging technology
    Optical Coherence Tomography (OCT) is a low-loss, high-resolution, non-invasive medical and imaging technology developed in the early 1990s. Its principle is similar to ultrasound imaging, the difference is that it uses light instead of sound.

  • Optical direct modulation and external modulation
    Optical direct modulation and external modulation
    Direct modulation of semiconductor lasers is to modulate the laser by superimposing the pre-modulated (AM, FM, PCM) signal current on the bias current of the laser. Because it is to change the intensity of light, it is also called intensity modulation. For digital transmission, although the speed is very high, only two working states of optical signal or non-optical signal are ...
