At an early stage in this project, Pete provided measurements and guidance about the most effective LED optics for the jaundice cure for new born babies. Full project description can be found at the Design That Matters website here. Uniform light with the fewest LEDs, to reduce cost and insure effective treatment.
Here’s a couple of our clients puzzling over some lens test data. This was an exciting day, to see this huge lens tested! The puzzling was over by the end of the day, but this is a better action shot.
the kind of arms to pick up things, not like the puny arms that a T-Rex has. That’s the word we hear from Bec Conrad, who’s taking a break from her work with animatronic dinosaurs (see this link here: http://www.dinosaurlive.com/funstuff/).
Bec is helping us make this motion stage, based on a salvaged DVD player, a platform for some new precision products. With an encoder capable of 15um resolution from Austria Micro, and controls theory support from Bec, we look forward to using this prototype in our shop to improve our optical measurements.
We’re using some Arduino boards for a variety of projects – to run the motion stage (25um resolution), to test LED colors, to run an oven for testing temperature compensation electronics. The add on boards (‘shields’ – since that means something else to me, I have trouble with that name) are a big help. We’ve been using SparkFun as our Arduino parts vendor, and we like ‘em.
For both a clinical test microscope, and a home theater HDTV projection display, the light from the source must be quite uniform.
To test some non-imaging illumination optics, we set up our digital camera, and wrestled with the RAW data files from the camera. Most cameras have some ability to ‘see’ infra-red, so we can also test the pattern from the remote control output, or for other purposes.
