Introduction to 3D Scanning Laser Modules

A laser scanning module is a device that acquires information about an object's surface by rapidly scanning it with a laser beam. It typically consists of components such as a laser source, a scanning mirror, a detector, and control circuitry. The laser source emits a beam, while the scanning mirror alters the beam's direction through rapid rotation or oscillation, enabling it to scan the object's surface. When the laser beam strikes the surface, a portion of the light is reflected back; the detector captures this reflected light and converts it into electrical signals. By analyzing these signals, the shape, distance, and other characteristics of the object's surface can be calculated.
