Face ID system works by projecting more than 30,000 infrared dots onto a face and producing a 3D facial map. VicoVR sensor uses a pattern of infrared points for skeletal tracking. Chiaro Technologies uses a single engineered pattern of infrared points called Symbolic Light to stream 3D point clouds for industrial applications
Three-dimensional face recognition (3D face recognition) is a modality of facial recognition methods in which the three-dimensional geometry of the human face is used. It has been shown that 3D face recognition methods can achieve significantly higher accuracy than their 2D counterparts, rivaling fingerprint recognition .
Making a 3D-model of a Viking belt buckle using a hand held VIUscan 3D laser scanner. 3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based
Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.
A face shape of vertices is defined as the vector containing the 3D coordinates of the vertices in a specified order, that is . A shape space is regarded as a d {\textstyle d} -dimensional space that generates plausible 3D faces by performing a lower-dimensional ( d ≪ n {\textstyle d\ll n} ) parametrization of the database.

Surveyor 3D laser digitizing systems measure parts of all sizes, including those with geometry. Inspection and verification applications, including process control and in-line inspection, reverse engineering, rapid prototyping, are aimed to be a major consumer of laser scanning systems in the future.

A coordinate-measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensors do exist.
