Imaging, Microscopy and More

This is good news! Sorry posting’s been light. I’ve been working on a project which I will post about quite a bit in the coming weeks. But for now – it’s a secret 🙂 -Austin    

This is a nice alternative to a $7,000 spectrophotometer. It’s also a lot smaller and hackable!  

Andrew York from the NIH has done this, and is reporting good results thus far. Interesting technique! I’m curious how the overall sensitivity of the instrument is, but the examples posted thus far look great! PDF  – Google Code Site – Nature Methods    

Yesterday evening I was able to collect a timelapse series of the annular eclipse. My location was outside of the complete annulus, but it was quite close! Below is a quick youtube video of the timlapse as well as a few stills. I used a Nikon D80 with a DX sensor, coupled to a 80-300mm…

This post will grow over time, but I’m posting this so that researchers and vendors have access to one single repository of filter info. Hopefully this will make all of our lives easier! Definitions: ET – Chroma name for a sputter coated filter. Multiband – filter set which allows multiple channels to pass through it…

I must apologize for my lack of posts – I’ve been traveling a lot these past few weeks for work. In my travels I’ve come across this exceptional timelapse montage from Shawn Reeder. He spent two years putting the shots together. Timelapse work is extremely difficult, and it takes a big investment on the photographer…

One of the most overlooked capabilities possessed by digital capture is what can be accomplished by image processing after capture. In modern EMCCD cameras, some processing is done directly in the camera head. Simple adjustments like background correction or shading correction are well known, but more complex operations, like HDR , or High Dynamic Range…

I had a customer recently ask for these, and I thought I’d post them. These are from Nikon Inc. I’ll also have them on the resources page for reference. These include Useful magnification, Brightness Factor, Refractive Index, Depth of Field at Image Plane, Depth of Focus at Specimen Plane, Useful Magnification and Infinity Optics Formulas.…

If you’re attending the training course on Fiji programming at Stanford, you can download the example files here.

Synergy Aircraft is making a push towards it’s next level of research in a composite blended wing/tail concept. They physics models show that the design should produce superior flight performance over several extremes of the envelope, i.e. low drag, but low stall speeds, good lift and good linear flow. They are saying Wednesday will be…
