In many circumstances, optical 3D measurement may replace tactile measurements made with mechanical gauges or coordinate measuring devices. It is used to verify that the geometric dimensions (size, form, and position) of components are correct. A light source (transmitter) that provides a unique, predetermined light signal to the test item and a receiving device (receiver) that captures the light signal are the typical components of optical sensor systems for 3D measurement operations. The item modifies the optical signal's amplitude, phase, polarization, or direction in a known way, which is then utilized as a measured variable. Depending on the measurement technique, the object's surface structure or 3D information can be inferred by analyzing this change.  

In the field of mechanical engineering, 3D measuring technology facilitates and expedites every stage of the injection molding, blow molding, and thermoforming processes: from the design and manufacture of prototypes and tools to the first item inspection reports, assembly analysis, and load testing. optical 3D coordinate measuring device that, regardless of the object size, enables non-contact measurements of the whole surface of tools, electrodes, prototypes, and injection-molded components. This technology even swiftly and thoroughly catches  complicated freeform features, unlike tactile measurement procedures. Full-field surface measurements provide targeted tool correction and a quicker first item inspection, which cut down on production lead times. The whole assessment procedure as well as the measurements may be automated for quality control that goes hand in hand with production.

Mold dimensions and tolerances are measured during the production process using optical measuring devices. Since they are a non-contact measurement technique, the mold is not physically touched, potentially reducing the risk of mold damage. Many characteristics on molds may be measured with optical measuring equipment. Coordinate measuring machines (CMMs), optical profilers, and three-dimensional scanners are some of the most popular kinds of optical measurement systems utilized in the mold-making industry. In general, mold makers can benefit greatly from the use of optical measuring equipment. They can aid in lowering expenses, shortening inspection times, enhancing quality control, and improving accuracy.
