2022-07-15 The thermal camera uses an infra-red detector and an optical imaging objective to receive a graphic representation of the infra-red radiation energy distribution of the target to be measured, which is reflected on the photosensitive element of the infra-red detector, thus obtaining an infra-red thermal image that corresponds to the heat distribution field on the surface of the object. This thermal image corresponds to the heat distribution field on the surface of the object. Next, let's take a look at the structure and applications of the thermal camera. Here are some answers.
