Hi,
some images from DT-9885, lens f=22mm
Regards

The side of a chest freezer. I did this one a couple years back but still pretty cool.

I put some images up under the Keysight U5855A thread but I probably should have put them here.
Puppy, puppy's thermal reflection looking back at him (in glass door), puppy drinking and then his thermal footprints left behind.

Camera: Flir E4+
Images upscaled to 640x320 with Photoshop.

1.  The image of my Laptop's DVD writer after a CD burning.

2.  Condensing Unit of a CCU (Close Control Unit) by Emerson.  I was impressed by the fact that the copper pipes look colder to the camera than the part of the pipe that was covered by a white sticker (label).  The emissivity of the sticker is higher than that of the copper.  (Two stickers in rectangular form.  One in the middle and one to the right part of the pipe)

3.  Condensing units of CCUs.

4.  A compressor's top part of a chiller.

A few of my holiday hi-res thermal snapshots made with a Therm-App imager, ThermApp Plus and Microsoft Image Composite Editor, often with cropping and light post-processing in Paint Shop Pro X.

Not seen many images from the seek so I thought I'd add a couple

I'm regretting buying the FLIR One looking at this resolution.

Rightly so, the images are stunning!

I no longer have access to an IR camera, but a few years ago in my previous company, we had one.
One *very hot* August day in South Texas, exactly at noon time, I saw two identical vehicles, but one was white and the other black.

They were parked at the company's parking lot so I ran for the camera.

Took several readings of the vehicle's painted surfaces (avoiding of course the engine bay), and the average white temp was like 49C, and the black one was about 88C.

Made me a believer that, if you live in place with hot summers, one should get light colored vehicles.

Software for image stacking (eg Registax, Autostakkert!) and compositing (eg Microsoft Image Composite Editor) means that you can get reasonable results with lower resolution imagers, as I'm sure others have mentioned elsewhere.

Here are some composite images I made with a Seek XR (206 x 156) before I re-homed it.

Apart from the well known issues with noise, sensitivity, linearity and limited actual resolution, the Seek XR performed reasonably well for the price.

I put together a quick video of some footages I've taken with the Therm-App 19mm and Therm-App TH 6.8mm

Here's an unusual one - a thermal sensor actually scanning. You'll probably have to click the image to see the animated GIF or a higher resolution version of the file on the Flickr site.

This is quite remarkable: I pointed a 25Hz Therm-App camera at the sensor of another Therm-App camera and I could actually see the scanning in progress!

The frame rate of the two cameras differs slightly, which is how come we can see this effect. What you're seeing is the sensor on top of the ROIC (read-out IC) becoming very slightly warmer as each row is read out. This is actually happening 25 times a second but because the two cameras are running at nearly the same frame rate we get a kind of 'stroboscopic' effect, very like the effect you used to see on TV screens being filmed.

There's a decent description of why a filmed TV screen appears to flicker (which works in the same way) here if you want to know more, and the short movie linked from that page shows exactly what's going on.

I found it utterly fascinating to see, and I've never heard of anything similar being filmed before. This is definitely not caused by any other artifact such as a lighting effect or anything physically moving, and when I swapped the cameras round I saw exactly the same effect - but with the motion going in the opposite direction.

Very high resolution stitched panorama of Gibraltar Airport and the Spanish town La Linea de la Concepcion.




This image is nearly 20 megapixels.

I had to fine-tune the jpg compression settings to make it fit the 1MB maximum file limit.

You'll need to download the image to explore it properly: it is well over 9,000 pixels wide. I think it's the most detailed thermal image I've ever made.

Imager: Therm-App Pro (uncooled LWIR 25Hz 640x480 <30mK)
Lens: 35mm f/1.1
Driver software: ThermViewer
Stitched by: Microsoft Image Composite Editor
Tweaked in: Paint Shop Pro

There are a couple of slightly iffy areas in this panorama due to issues with the stitching but overall I'm quite pleased with the result. I hope to be able to make even better-quality images in the future: this capture was done under a certain amount of time pressure and with a slightly flaky imaging setup.

There is a better-than-HD resolution video of the central portion of the image on Flickr.

Also on Flickr is a high resolution panorama of Gibraltar town and the harbour taken from a slightly different location.




The image below is a Barbary macaque (also known as a Barbary Ape, although it's actually a monkey), again made with the Therm-App Pro 35mm F/1.1 and ThermViewer, black hot. I was only a few feet from the animal and struggled with the relatively narrow DOF of the lens at that distance.



There's a close-up thermal portrait of the same animal here and a visible light view from a similar angle here.

That is creazy.

Here are two images of my breath. You can tell the breathe-in and breathe-out from my nostril.

Hot off the press, "partly empty" moon.

Camera: Late model Seek
Lens: 100mm ZnSe lens in place of stock lens.

Lens kluge shown in 3rd image.    Hopefully I'll put together something more solid later on...and get the software adjusted for that lens so I can show temperatures.

[Vipitis]

whew, those are some nice view for the lens!

I want to request more - using a white hot greyscale palette and locking it. Take a few in rapid succession and stack them in astrophotography software to reduce noise and eventually post process for sharpness.

I am jealous.

@Vipitis, It could be a while before I can do that.  Although I have seen it discussed on this site, I have never tried the image stacking.  I see there are a few such programs for Linux, though; lxnstack, Siril, Gcx...
It might be best to get the lens calibrated into the software first also.

On the beach in Malta. Probably my favourite thermal image.

Therm-App, 19mm lens, stock app (2014 incarnation - its appearance has changed a bit since then).

A shot of my DIY gimbal after some first testing - the steppers are getting quite warm. ;-)
