There may also be blind spots on the target where the camera cannot detect the light. However, a disadvantage of these scanners is that the reflected light may change depending on the material and shape of the target, which can make it impossible to determine exact coordinate information. These scanners are also ideal for use with targets that may change shape due to contact with a probe or other device. Laser-based scanners offer detailed coordinate information, while pattern light projection scanners are known for their ability to quickly measure a wide area. On the other hand, scanners that use pattern light projections shine light onto a target in a striped or other pre-determined pattern, and a camera detects any displacement or distortion in the lines to determine the shape of the target. The coordinates are then obtained by measuring the time difference and reflected angle of the light. Scanners that use lasers irradiate a target with a laser beam, and the reflected light of the laser is then detected by a CMOS sensor or other device. There are two types of non-contact 3D scanners: those that use lasers, and those that use projected light patterns. Non-contact 3D scanners measure targets using a laser or other light source, and the measurement results are converted to 3D data.
