Exploring Optical Measurement and Learn Wide-Ranging Applications
Optical measurement refers to the use of light-based technologies to capture, analyze, and interpret the physical dimensions, shapes, and properties of objects. Unlike traditional mechanical tools such as rulers or calipers, optical methods rely on advanced systems like lasers, cameras, and sensors to provide precise and often non-contact measurements.The idea of using light for measurement is not new. It originated with basic optical instruments like telescopes and microscopes, which magnified objects to reveal details. However, with the advancement of lasers, digital imaging, and computational processing, optical measurement has become a powerful and versatile tool.
