Thermal imaging works in daylight, but it is not as effective as it is in darkness. Thermal imaging uses infrared radiation to detect temperature differences, and in daylight, the sun’s radiation can overpower the infrared radiation that thermal imaging relies on. This can make it difficult to detect smaller temperature differences. 

In addition, the sun’s radiation can cause “noise” in the thermal imaging image, making it difficult to make out details. The sun’s radiation can also cause “blooming”, which is when the image appears to have a halo around it. This can also make it difficult to make out details. However, there are ways to reduce the impact of the sun’s radiation and still make effective use of thermal imaging in daylight. For example, using a polarizing filter can reduce the amount of sunlight that reaches the camera, allowing for clearer images. 

Additionally, using a higher gain setting can help reduce the noise in the image. Overall, thermal imaging can be used in daylight, but it is not as effective as it is in darkness. However, with the right settings and filters, it is possible to make effective use of thermal imaging in daylight.
