advancesnoncontact
Advances in noncontact technologies refer to methods and systems that gather information from objects or people without direct physical interaction. These techniques are used to measure geometry, surface properties, temperatures, or physiological signals, and increasingly incorporate artificial intelligence for processing and interpretation. Recent progress across industries has expanded accuracy, speed, and portability of noncontact solutions.
Optical metrology has benefited from higher-resolution cameras, structured light, and time-of-flight sensors. Modern 3D scanners use
Noncontact sensing and imaging enable monitoring of physiological signals and human activity without contact. Camera-based remote
Noncontact measurement supports robotics and automation through vision-based pose estimation, optical sensors for material characterization, and
Challenges include sensitivity to surface reflectivity, ambient light, occlusion, and environmental conditions, as well as data
Future directions emphasize sensor fusion, AI-driven interpretation, edge computing, and the development of compact, affordable sensors
