Laser scanning - Wikipedia
Within the field of 3D object scanning, laser scanning (also known as lidar) combines controlled steering of laser beams with a laser rangefinder. By taking a distance measurement at every direction the scanner rapidly captures the surface shape of objects, buildings and landscapes.
Laser Scanning: What it is and How it Works | Coherent
Laser scanning is simply the moving of a laser beam across a surface, whether it’s to read a product barcode, project a laser light show, or weld an autobody.
Laser Beam Scanning for AR Display • How: Creating an image by scanning color lasers thru MEMS Mirrors and modulating the lasers per pixel. Why: • Always in focus • No Blur Low Persistency • 10nsec persistency per laser pixel vs milli seconds of microdisplays • Viewer Comfort Low Latency • One pixel displayed at the time.
• Laser Diodes Drivers • <500ps rise/fall time for crisp pixels • Ultra low power –Optimized for AR • 3 / 4 channels (RGB / + IR) • Control Loops and Video • HW / SW Mirror control loop • Laser control loop • Calibration • Video processing • Relay Optics • ST patented design to maximize performances with waveguides
In recent years, the confocal Laser Scanning Microscope (LSM) has become widely established as a research instrument. The present brochure aims at giving a scientifically sound survey of the special nature of image formation in a confocal LSM.

Jun 15, 2024 · A laser scanning microscope uses focused laser beams to scan specimens, providing high-resolution images of biological and material samples. It’s essential in research for detailed cellular and structural analysis.
Focus on display is necessary, but many more technology challenges exist. Delivering compelling experiences: low latency, low power, light weight, right specification (e.g. FoV, resolution etc.) and an intuitive user interface. © STMicroelectronics - All rights reserved.
