Technical details and manufacturing context for Laser Transmitter

Definition
The laser transmitter is a critical sub-component of a LiDAR (Light Detection and Ranging) sensor system. Its primary function is to generate coherent, high-intensity pulses of laser light, which are then emitted into the environment. The emitted light reflects off objects, and the returning signals are captured by the sensor's receiver to calculate precise distances and create detailed 3D maps of the surroundings.
Working Principle
The transmitter typically uses a laser diode or fiber laser. An electrical current is applied to the laser source, stimulating the emission of photons. This light is then collimated and directed through optical elements (like lenses) to form a controlled beam. The system is pulsed at high frequencies, with precise timing controlled by the LiDAR's processing unit to correlate outgoing pulses with returning echoes.
Common Materials
Semiconductor (e.g., Gallium Arsenide), Optical Glass, Aluminum Alloy (housing)
