Can thermal imaging be used during the day?

Thermal imaging can be used day and night. As long as the object (heat energy) emits infrared rays, it can receive imaging within a certain distance.

Thermal imaging is a kind of detection equipment that detects infrared energy (heat) through non-contact and converts it into electrical signals, and then generates thermal images and temperature values on the display, and can calculate the temperature values.

In fact, the detection principle of infrared thermal imaging is not so mysterious. Physically speaking, the human body is a natural source of infrared radiation, constantly radiating and absorbing infrared radiation to the surroundings.

The normal temperature of different parts of the human body is stable and special, and different temperatures have different thermal fields. When a certain part is diseased or abnormal, the blood flow here will change, leading to the change of local temperature.

According to this principle, infrared thermal imaging collects infrared radiation of human body through thermal imager, converts it into digital signal, and then generates color thermal map. Experts in the physical examination center judge the location, nature and degree of human lesions according to these thermograms.

Thermal imaging is a more advanced observation technology, which can make us have bad weather and poor eyesight during the day; Observe the surrounding environment and things at night when visibility is low or completely out of the light source.

In recent years, thermal imaging products have blossomed in the market, each with its own advantages. With the continuous development of technology, many friends have some disjointed and cognitive errors in their basic cognition of thermal imaging. The most typical ones are the size of the objective lens and the quality of the imaging results.

A few years ago, because the technology of digital infrared thermal imaging is not very advanced, with very low-level chips and simple software programming, in order to achieve better picture effect, we can only enlarge the magnification, but the image is blurred and the field of vision is too small, so we can only use enlarger lens.
