Request acknowledged. If I have the time, I'll assemble some winter images and data, and post them here. IR-V

Sure. 17 micron, VOx microbolometer; with 50mm germanium lens. IR-V

You're welcome, MM! Hopefully this will intrigue others into doing the same with their thermal sensors, and this board / forum will become a master repository of the diversity of carefully documented, thermal imaging experiences. IR-V

Below are some thermal images of the same, outdoor view over a period of three summer months, with narrative of the environmental and weather conditions. It is particularly interesting to observe the conditions and thresholds that influence radiance versus reflection of LWIR wavelengths. The...

Actually, the thermal images themselves can be indexed on a quantitative measure of their "thermal contrast", which is what is generally equated by a human observer as the quality of the thermal image. The engine doing this work would be an analytical tool processing the image data from the...

Thanks for appreciating, Hdfireman! IR-V

The only charts that are readily available are the ones that demonstrate the thermal radiance of different materials (i.e. vegetation, rocks, standing water, etc.) - but even those will be variable by time of year and weather conditions. Numerous academic studies in thermography show the...

Hello Vic. That is correct - ADUNS is overlay and not actual fusion of the image planes at the capture level. But, there is a certain opportunity to be had with the overlay approach for modular integration that the user can configure, tune, and integrate -- and for all practical purposes, the...

This is where fusion / dual-band imaging is king. If the sun doesn't come out for an entire day or more, this further compounds the cool and wet (or humid) and windy conditions which degrade the thermal imaging. Also, tropical environments where everything is heated to high temperatures and...

In this case, unsafe is variable to the periodicity and cumulative duration of the exposures and how each observer's eye tissues respond. The IR emission that comes out of the ocular lens of the Terrapin is equal to flashing a Class 1 laser directly into your eye from a couple inches away. The...

On the Vectronix Terrapin (PLRF-05) and the Vectronix PLRF-10/15/25 series, the objective lens that the user views through is the same lens from which the laser pulse is emitted. Anything placed in front of that lens will block the emission of the laser pulse. Thus, you cannot use a clip-on...

Thank you for appreciating, shurt! I appreciate very much your kind words. Congratulations on your first thermal imager purchase! I hope it does for you, what it does for me -- as a gateway, opening doors to and exciting, new paths for exploring an endlessly fascinating, "other" dimension. IR-V

Hello Cake5150, Thank you for your kind words, and for your encouragement to write / publish. Your ETA is right on track. Full modularization of all the [thermal imaging] subsystems will bring more performance "power" and value to the consumer, and sooner! IR-V

Thank you, 10p5s. I coded everything from scratch, including the lightweight operating system. I also developed my own algorithms. IR-V

Thank you for appreciating, Nukes. It is always a pleasure to share information with you! IR-V

Hello Vic, Alas, a white / gray, center stripe has formed in my beard (goatee) in the past year. If not an artifact of age, it must be all the skunk-works rubbing off on me! ;-) IR-V

Thanks for appreciating, Delta4-3, and for forgiving me for my verbose posts! I usually have several, run-on sentences in rapid succession before I crash and let the photos finish the explaining! :-) IR-V

Thank you for your kind words, SkyPup -- it is always a pleasure to share the latest with you. I greatly / deeply respect your professional background / career and expertise in the sciences and engineering also. This latest project has taken a lot of my available cycles, as I rolled up my...

Thank your for your tag, GhengisAhn. IR-V

I've just returned from presenting to an engineering college at a defense university. The topic of my lecture was on the technology variables key to advancing image quality and imaging performance on portable, thermal sensing equipment: 1) Lens system 2) Core resolution and sensitivity (at...
