Optics of Photosynthesis Lab

Our lab's mission is to understand the links between optical, biochemical and functional traits of vegetation.

This week in @Nature, on our long-term field observation in @HyytialaHY, @INAR_fin, @ForestSciences. https://t.co/r3cWDHe8mh. Collecting key data to understand link between radiation and plant physiology.

We join CREDIBLE action to build carbon farming markets and policies we can trust!

@helsinkiuni takes the lead in the focus group of proximal sensing and digitalization for carbon farming.
Interested in joining the focus group?

Season's greetings from OPL! Tested: 1)Red #Poinsettia leaves absorb PAR but do not fluoresce👉they do not photosynthesize, 2)We have a fluorescent logo😮! No wonder #SIF is great at capturing the optical expression of photosynthesis in its purest state. @ForestSciences,@INAR_fin

You can find some more information about the method here https://t.co/7KB5paB2NZ

Ever wanted to take a hemispherical photo up in the canopy? our new drone method solves this problem...sans hemispherical camera! @NewPhyt

#Hyytiälä has been canofied! https://t.co/W7tiGqk576

[Optics of Photosynthesis Lab @OptPhotoLab]

@TropiDry @CanopySEE @PlantSpps @ForestSciences It works on my iPhone 7. Please try it out, feedback appreciated!

Is your hemispherical photography kit weighing you down? Craving spontaneous #forest structure-related fieldwork? Then https://t.co/drPlBBih89 is for you! Use Canofi to produce hemispherical photos with your phone, no additional hardware required. @PlantSpps @ForestSciences

[Optics of Photosynthesis Lab @OptPhotoLab]

Canofi is a work in progress (source code on GitHub) improvements and suggestions welcome via [email protected]

[Optics of Photosynthesis Lab @OptPhotoLab]

Canofi works by transforming panoramic imagery to a fish-eye type projection in the comfort of the web-browser using the excellent @pyodide. Find out more here https://t.co/xMvjf3UOJw

We are proud to share our @NaturePlants Perspective on solar-induced chlorophyll fluorescence: what is it? what could it be used for? what are the next steps? Check it out: https://t.co/mUnwsJEZPq @INAR_fin @viikki_plants @ForestSciences @SuomenAkatemia https://t.co/0cIBBHryPr

@vis_tronquitos We were more than happy to host you Vicent! And you are always welcome back, we are always short of brilliant students 😊! Enjoy the well deserved late summer break

Dancing in the drought. Dynamic canopy structure and foliar physiology are captured by Solar-induced fluorescence (SIF) during water stress. Read our open access paper: https://t.co/0maa1VwQ4p @INAR_fin @Viikki_plants @AgriForHelsinki @fgi_nls @dronefinland

We simulated the faint glow of #fluorescence in a virtual 3D forest. Check out the open access paper here https://t.co/rMSuMKEUpv #TLS #LaserScanning #photosynthesis

[Christian Frankenberg @chr_fronge]

Check out our new paper (congrats Troy @photo_spec ) showing how well SIF can be used for evergreens: Mechanistic evidence for tracking the seasonality of photosynthesis with solar-induced fluorescence https://t.co/yoTEr3knbF

[Life Sciences University of Helsinki @LifeSciHelsinki]

Groundbreaking method from @OptPhotolab to observe from distance the full spectrum of fluorescence of mature trees in the forest. This brings us one step closer to remote sensing of terrestrial carbon sinks and vegetation health. @INAR_fin @helsinkiuni https://t.co/2JQfRR0IsM

The chl fluorescence emission distribution of whole tree crowns cannot be measured, right? It can at night! New @OptPhotoLab work https://t.co/iYExnWrQ3i #remotesensing #photosynthesis #Fastcam17

[Optics of Photosynthesis Lab @OptPhotoLab]

Check out new work from @OptPhotoLab member Paulina Rajewicz who measured fluorescence from broad leaves and needles https://t.co/W7eQBsOauU @RemoteSens_MDPI

@ryuyr77 @kinznice @geoxiyang @chr_fronge @DJPMoore @Wkolby That is a really good idea (camera)! We will ask details :)

[Optics of Photosynthesis Lab @OptPhotoLab]

@ryuyr77 @kinznice @geoxiyang @chr_fronge @DJPMoore @Wkolby Great work! Yes, having a sensor-branch-shoot-needle that move together (in the wind) is the key to keep needles in place for months. Yields typically stabilize to the new light environment after 2-3 days. Good luck with measurements!
