Infra-red thermography
Infra-red thermography Infra-red thermography is the science of using electric optical devices to detect heat from structures or equipment being inspected. Any object that has a temperature above absolute zero (-273.15 °C = 0 K) emits radiation in the infra-red region. Human eyes can only detect visible light (or visible […]
