Why thermal imaging night vision devices cannot form an image through glass?

Update time : 2024-06-13 11:03:19

The reasons why JAXY thermal imaging night vision devices cannot form an image through glass are mainly as follows:

1. **Reflection of Infrared Radiation**: Glass has a high reflectivity for infrared wavelengths, so when a thermal imaging device is aimed at glass, it primarily receives reflections from the glass surface rather than the infrared radiation emitted by objects behind the glass.

2. **Limitations on Penetration of Infrared Wavelengths**: Glass typically blocks certain infrared bands, especially the light within the infrared band range that the thermal imaging detector can receive, making it difficult to penetrate the glass.

3. **Technical Limitations**: The core sensor technology of thermal imaging devices limits their ability to penetrate transparent objects. Although there are special cases where certain types and configurations of glass can allow varying degrees of infrared light penetration, this is not common and usually requires specially designed equipment and materials.

4. **Measurement Accuracy Issues**: Thermal imaging devices need to maintain a certain distance from the object to obtain accurate temperature measurement results. When aimed at glass, due to the thickness and transparency of the glass, the thermal imaging device cannot maintain a sufficient distance from the object behind the window, affecting the accuracy of the measurement.

5. **Impact of Highly Reflective Surfaces**: In addition to glass, other highly reflective surfaces can also affect the imaging of thermal imaging devices, making it difficult for the thermal imaging device to perform accurate temperature measurements through these surfaces.

In summary, JAXY thermal imaging night vision devices have certain limitations when it comes to penetrating glass for detection, mainly due to the reflection and penetration issues of infrared radiation, as well as technical and measurement accuracy limitations. If thermal imaging detection through glass is required, it may be necessary to consider other technologies or equipment.
