Laser guidance is a technique of guiding a missile or other projectile or vehicle to a target by means of a laser beam. Some laser guided systems utilize beam riding guidance, but most operate more similarly to semi-active radar homing (SARH). This technique is sometimes called SALH, for Semi-Active Laser Homing. With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known as painting the target , or laser painting ). The missile, bomb, etc. is la ....etc

ppt for laser guided wheelchair for the blind

The laser-equipped wheelchair scans the environment as it moves forward and creates a 3D map of the surroundings. But wait, you say, blind people can't see? Rather than a visual image, the map information is sent to the wheelchair occupant using a haptic interface. They may not be able to see the door in front of them, but they will be able feel it. A joystick will let them move around any obstacle in their way.

More than just a concept, visually impaired student Daniel Innala Ahlmark has already ....etc

The laser guide directs a robotic system to a target position by means of a laser beam. The laser guide of a robot is realised projecting a laser light, processing of images and communication to improve the precision of the guide. The key idea is to show target positions to the robot by projecting laser light instead of communicating them numerically. This intuitive interface simplifies robot steering while visual feedback improves positioning accuracy and allows for implied localisation. The guiding system can also serve as a mediator for mult ....etc
