Does anyone know how much it costs to get a FLIR C3 or C5 calibrated? I"ve got my hands on one and the C3 is giving numbers almost 10 degrees below "the actual temperature" (please don't laugh at my wording @Protons4B ). Altering the emissivity setting doesn't allow me to tweak things and I suspect it has to go back to FLIR. So I'm wondering about the order of magnitude for the cost of calibration.

Functional stay-green supports complete grain filling in wheat genotypes, but must be carefully distinguished from cosmetic variants. Image-based monitoring of leaf senescence and canopy temperature dynamics can differentiate between ideotypic and cosmetic stay-green in high-yielding environments.

#ImageThermique d'une assise de chaise en bois. C'est ce qu'on appelle chauffer la chaise, littéralement 🤡

#cameraThermique #thermographie #thermalCamera #thermography

Image thermique d'une assise de chaise en bois en contre plongée, prise juste après quelques minutes d'utilisation. L'emissivité n'a pas été réglée en fonction de celle du matériau. Les temperatures apparentes sont donc fausses. En revanche, ça permet de voir les différences de températures d'une zone à l'autres.

#Température de surface du dock du boulot.

C'est pas le miens, donc je ne m'amuserai pas à le faire fonctionner coque démontée… Mais j'aurai été curieux de voir les températures les composants plutôt que celle de la coque chauffée par les composants.

Dommage, c'est trop petit pour servir de chauffage d'appoint en hiver au bureau 🤡

(Bon, en vrai on a vu bien pire comme apoareil électronique qui chauffe, hein…)

Image thermique basse résolution d'un dock USB C Thinkpad, en plastique noir (emissivité 0.94).

Prise avec une caméra dont D:S est de 112:1, à une distance d'environs 30 cm.

À l'arrière du dock (au dessus du Dock sur l'image car image en contre plongée), on peut deviner que le dock a été déplacé a cause de la trace de chaleur laissée sur le support (sous le dock avant qu'il ne soit déplacer.

Le point le plus froid de l'image, un bureau en bois repeint en noir, dans le coin haut gauche (cible bleue) est 25,3°C.

Le point le plus chaud (cible rouge), situé sur dock même, presque au centre mais un peu plus haut, proche des connectiques où se trouve un ensemble de zones les plus chaudes, est à 46°C.
Le point central de l'image (cible blanche) 36,6°C, se situe un niveau d'un connecteur HDMI en plastique gris relativement foncé, pas vraiment caoutchouteux mais pas dur non plus. Situe un peu plus haut que le point le plus chaud.

The #asphaltcollector for our project "Sozial100%Erneuerbar", a social housing project with 100 % renewables for heating and cooling (#geothermal, #wastewater, #solarthermal and the #asphaltcollector) is in operation! We started with #monitoring, #thermography and surface temperature measurements. The pictures are from end of May and we already had temperatures well above 50 C on the surface! urban surfaces are a valuable heating source for space heating. tinyurl.com/ye296pma

New paper❗ Our colleague Udo Netzelmann has published a paper entitled "Theoretical and Experimental Analysis of the Thermal Response in Induction Thermography in the Frequency Range of 2.5 Hz to 20 kHz". And: It's open access. Congratulations!

@AlanBell I would hire one if you can. Most cheap, freely available ones won't have the spatial res. to allow you workout what's happening with sufficient detail. You also need to take care processing the results - and drawing the wrong conclusons. There are free tools such as #FLIR tools, that allow you to adjust range, span, emissivity of the images (rjpgs). Quick survey tip: cold night (>10°C bet inside and out), low humidity are your friends. #thermography #thermal #spacecraftengineer

One exciting project I was involved in this past year was led by Nathan Vidal, who was interested in the interplay between #physiology & #cognition.

We were going to study how #attachment relates to #BAT activation.

A seemingly cool method was via #infrared #thermography, as #BAT is usually detected via radioactive tracers.

Turns out that it is harder to study #BAT than we thought!

The method wasn't as reliable as previously presumed.
