    Night Vision Impacts of Climate / Weather / Environment on Outdoor Thermal Imaging Quality

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

    Night Vision Impacts of Climate / Weather / Environment on Outdoor Thermal Imaging Quality

    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

    Night Vision Impacts of Climate / Weather / Environment on Outdoor Thermal Imaging Quality

    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...

    Night Vision Thermal performance weather conditions affect

    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...

    Night Vision Thermal performance weather conditions affect

    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...

    Night Vision Thermal performance weather conditions affect

    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...

    Night Vision Thermal performance weather conditions affect

    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...

    Night Vision Vectronix Terrapin LRF clipon?

    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...

    Night Vision Vectronix Terrapin LRF clipon?

    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...

    Night Vision Optimizing Your Thermal Imager

    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

    Night Vision Optimizing Your Thermal Imager

    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

    Night Vision Optimizing Your Thermal Imager

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