electr_peter   are you telling me I've been vaporize ?  :-DD .same thing happened to my cat ? (sorry for my bad English ). this occurs when i try to get the radiometric data  from the hidden preferences in the app of the phone .this is how i get the frame rate .just hope Seek will fix that .

Bruno those last few pics are very grainy why is that?
Not sure. Maybe there isn't a big temperature difference from thing? Or maybe they aren't hot enough to radiate a good amount of IR.
A thermal camera requires heat to see things. Much like a visual camera requires light. So I'm guessing low heat=low light in a normal camera. Which gives grainy images. Correct me if I'm wrong.

Does Therm-App support calibration against flat surface (blackbody)?
That should really lower the amount of noise in images...

I don't think it has. Or at least I'm not aware of it.

Camera: Therm-app TH
Lens: 6.8mm f1.4

Here is some more. One in rainbow and not her in hot white.

TE-Q1 plus 13mm F/1.0 (black white hot)
1:1 image of raw radiance with linear color scale

Got this just a couple of days ago and I am quite impressed by the image quality (sharpness/noise level)  ;D

Therm-App Plus (3rd party app) does, however a lot of the noise is because Bruno is using a f/1.4 lens.

So why is it that the 1.4 lens has so much noise in low temperature differentials withing the photography  frame?

Some comparison between thermapp Opgal app and the ThermAppPlus.

What I realized is that you need to calibrate the noise reduction on the ThermAppPlus  every time you start the app. Otherwise you see no difference.

That makes sense.
You will get best (noiseless) images if you let Them-App run for a few minutes so that sensor reaches it's stable temperature and then do the calibration...

But this is on the ThermAppPlus only. And you need to hold down the button to analyze. It's weird that I have to do it every time I launch the app. It doesn't save the settings.

It wouldn't really make sense to have a "Save" calibration option...
Noise is totaly different 1sec after startup v.s. 5min after startup.

So it's best to do the calibration just a moment before you want to take a noiseless thermal image.
And do it multiple times if you take multiple thermal images. That is if you want a perfection.  ;)

Some thermal modules have a shutter which does the calibration every few seconds...

Ohh ok makes sense now. Yeah then it works well to reduce noise in white hot. Not so much in rainbow. Rainbow works better on the stock Opgal app. Much better colors and smoothness of sharpness in the images from stock Opgal app.

Thermal imager: Bullard eagle eye, S300A(BST) core inside.

Recorded using a Samsung cellphone through the TIC's screen, then took screenshot from the video, unedited.
It would be better on direct video output I think.

My frist Panoramic that is made up of 9 images stitched together of my street. There was no lights on the street, so it was pitch black.
Need to practise more.

I got PM'ed regarding the usability of the ThermalExpert for piping and leak detection, so here are two images of the floor/roof heating where I live (white/hot with linear scaling).
Temperature difference in the roof is roughly 2K while on the floor it is significantly less due to insulation and wooden floor.

Using an E4 for tire / suspension analasys at track days.



Toyo R888?

I tried that on my car too, but my tires cooled down rapidly and by the time I got to take a photo of the fourth tire, it was already significantly cooler that the other three.

Camera :  Flir E4+
Pictures : Resolution enhanced with Photoshop (800x600)

1.  Conductors and Fuses of a Power Factor correction unit.  (Warmer wires indicate that the capacitors absorb higher current than their nominal value)

2.  A stand-by Generator. (It is hot due to the water heater that keeps it warm and ready to run.  Water heater is located at lower left to center of the system)

3. The compressor of an air dryer system used in underground cables.

TE-Q1+ 13mm
Just stumbled upon a hedgehog in front of our building... final distance was roughly 1m and I still couldn't see a thing with my eyes.
Flir like coloring and white-hot incl. temperature scales.

Wow this is like a pornsite to me, just love thermal images.
This is a picture from me, taken with a E4 upgraded

it is floor heating on a toilet.
