High resolution does work better

This thing is great, thermal imaging sensors seem way too expensive.

One is enough. I used to make it 90640 resolution, but the refresh rate is too slow.

It’s so expensive. Many years ago, our company looked at it again and again, but couldn’t bear to part with it.

What's your resolution? It looks very clear!

The one I bought is a mobile phone thermal imaging, which is about 2500 after the discount. This price is OK

Our area was quite large at that time, and it was about 20w

The image must have been processed, so it displays smoothly.

Two years ago, I bought a domestic T2S+ from Arrow Optoelectronics. It can adjust the macro distance and is specially used to observe the heat generation of circuit board components. The heat generation of the power supply circuit inside the chip can be clearly seen. The price is also around 2500, and the resolution is also 256x192. I applied for a return after playing with it for a few days, and I rarely use it. I bought it only when I needed it for a project at that time. For this reason, I also studied thermal imaging knowledge for a long time. In fact, the thermal imaging sensors of several domestic companies are better than the sensors used by Fluke. These things are all export-controlled, and the export of high-resolution thermal imaging sensors abroad is not allowed.

Congratulations to the moderator for the new tool. You can test it more and see the effect.

If the area is large, it doesn't have to be that expensive. Put it farther away. For example, the collection distance can reach 5m. Maybe your resolution is too high.

With a 25Hz refresh rate, there is basically no problem with observation and video recording, but this thing will automatically calibrate, and the picture will freeze at that time.

Indeed, there are many competing products. Arrow Optoelectronics has a wireless one that is also pretty good. I hesitated for a while. In fact, there are many domestic handheld

If you need it, you can come and borrow it.

Is it auto focus calibration?

wangerxian posted on 2024-6-21 17:52 Is automatic calibration focusing?

If it is stuck, it is non-uniformity correction

Around 2009, the clarity requirements were indeed quite high and the company was reluctant to do so.

wangerxian posted on 2024-6-21 17:52 Automatic calibration is focus, right?

It is not focusing, but a calibration of the ambient temperature, a bit like the self-zeroing operation. The black baffle covers the lens and collects data as the basic value, similar to this
