Light is a powerful sensing mechanism. A beam of light can be used to detect whether an object is present or absent, understand surface characteristics of an item, and explore the composition of a material by shining light through it. Optical sensing techniques have been prevalent, not just in real-world applications but also in academic science experiments and during microscopy sessions, to sense movement.
The simplicity of optical sensing enables object detection in a very straightforward approach. Anyone can mount a photosensor opposite a light source to detect an object. However, optical sensing becomes crucial in extreme medical environments where reliability and consistency are critical for safety and well-being.
