3D LASER SCANNER

A 3d laser scanner is a device which is used to scan any 3d object to get its shape and dimensions. It is usually used in reverse engineering to manufacture any objects used in defence, aviation and the manufacturing industry, etc. It usually works on three methods: time-of-flight (measuring pulse travel time), phase shift (comparing light wave patterns), or triangulation (using angles to calculate distance).

WORKING

When a laser scanner projects a light through a laser. It first passes through optical lenses to focus on a 3D object, which later strikes back after reflecting through the camera scanner. After this, the scanner calculates the distance to the surface for each laser point along with specified angles. After collecting these million coordinates through the device, it forms a point cloud for digital representation of the object’s shape. After this, the software takes multiple scans to convert this point cloud into a 3D mesh or CAD model for printing
