Top Uses for 3D Optical Measurement

3D optical measurement involves the accurate and precise use of the 3D tool with optical measurement sensors to determine the dimensions, sizes, textures, and other features of an object. After the object has been measured with the sensors, the data is used to create a 3D model of the same object.

Although there are many applications of 3D optical measurement, the top uses include:


  • 3D color digitisation


This includes the use of 3D optical measurement for setting and controlling the color of 3D objects independently. 3D optical measurement enables the users to improve the quality of the color of a 3D object. This helps to determine how the color will look when applied on the real image itself.


  • Online calibration and validation of objects


Instead of measuring the tools physically, 3D optical measurement allows the calibration and validation of different objects online. These objects include gauges, jigs, and fixtures. Notably, calibration refers to the accuracy of the tool to suit the known standard while validation means the process of determining whether the tool or object meets its intended function. So, with the use of 3D optical measurement, these tools can be calibrated and validated online without the need for physical presence.


  • FEA simulation verification


Another top use of 3D optical measurement is for verifying FEA simulation. This means it is used for checking if the finite element analysis (FEA) has been done correctly or not. This process involves the simulation of how the manufactured product or tool will function or react when used in the physical world.


  • Analysis of cast and forged components


Forging and casting are important processes in the manufacturing industry. To analyse the cast and forged components, 3D optical measurement is usually used. This measurement is generally fast, safe and more precise than most other methods.


  • Quality control of turbine and fuel production


3D optical measurement is also important for testing a sample of fuel tank and turbine. This measurement is to ensure that there is a basis for comparing them to the specifications. This process helps in regulating the standards of turbine and fuel tank.


  • Mobile optical metrology in injection moulding


Basically, this is the process of forming parts of an object through the injection of molten materials into a mould. For the success of this process, 3D optical measurement is usually required.


  • Inspection of plastic components


To check the authenticity of plastic components, 3D optical measurement is sometimes used. It tests whether the materials used are genuine or not.

Other top uses of 3D optical measurement include 3D metrology for reverse engineering, control of dimension and shape of sheet metal components, and surface verification and CFD analysis on the space vehicle.
