Scanning laser beam devices
WebLaser scanners. Laser scanners are commonly used in retail and logistics environments. Depending on the model, laser scanners may use a wide stationary beam to scan an area, a moving beam that scans each line of the barcode individually, or multiple beams that scan barcodes from various angle simultaneously. Linear imagers. WebIn these laser-beam-scanning architectures, there is a tendency to use an optical engine formed from micro-optics, lasers and MEMS mirrors. The output of red, green and blue lasers is combined and collimated with micro-optics, before it is directed at MEMS mirrors that are scanned in two dimensions to generate an image permanently in focus.

WebEssentially, LiDAR is a ranging device, which measures the distance to a target. The distance is measured by sending a short laser pulse and recording the time lapse between outgoing light pulse and the detection of the reflected (back-scattered) light pulse.
