Lasers are used in 3D scanning by projecting light onto an object and measuring the reflection to calculate distance, creating a detailed "point cloud" of millions of data points that form a 3D model. Scanners use methods like Time-of-Flight (ToF), measuring the time for pulses to return, or Laser Triangulation, using angles and known sensor positions to determine depth. This process captures precise geometric data for applications in architecture, engineering, gaming, and manufacturing.
A laser diode is a semiconductor device that emits coherent light via stimulated emission, which is more complex and responsive than a light-emitting diode (LED). ‘Laser’ stands for Light Amplification by Stimulated Emission of Radiation.
Light-emitting diodes (LED) and laser diodes (LD) both generate light via electron-hole recombination. They both have a PIN diode at their heart. Even their names sound similar.So, how are they different?Let’s start by looking at how each is used, before learning what design differences turn LEDs in
BU-Laser is a manufacturer of laser modules from 375nm to 1064nm. We are also the distributor of semiconductor laser diodes; we cooperate directly with Nichia, Sharp, Osram, QSI, Rohm, Mitsubishi, Ushio, Arima and many other brands.
