Imaging Lightly: May 2012
http://imaginglightly.blogspot.com/2012_05_01_archive.html
Friday, May 25, 2012. POC Diagnostics - A walk in the PARC. Hey everyone. I’m back! It’s not as if stuff hasn’t been happening around here. Dusty blogs = all work less play. Yesterday I attended a very inspiring talk and I decided today I just have to take an hour off and summarize it here! It was Peter Keisel. From the Palo Alto Research Center. I had been looking forward to meeting Peter Keisel and hearing more about his work. Finally everything came together at the N-Cal OSA. Subscribe to: Posts (Atom).

Imaging Lightly: June 2013
http://imaginglightly.blogspot.com/2013_06_01_archive.html
Tuesday, June 25, 2013. Many should be better than one. Multi-aperture imaging. What is that? Many cameras (lenses/apertures) that work in some synchronized fashion to give something more than a single camera. typically wider field of view or more resolution. Multi-aperture imaging has been noticeably prominent at many places in the Imaging Congress. And I’ll probably write a bit about it here. The James Webb Space Telescope has many foldable. Segments working together to form a single pupil aperture.

Monday, July 15, 2013. Imaging Congress - final summary. Hey everybody. the last installment of my Imaging Congress talk summaries. Other than the last few posts there were a lot of interesting talks, several in the areas of lightfields/plenoptic systems, 3D capture and display and structured light. I can't write about everything, but here's a shot! Quick ride in the Metro, the Washington Monument and the US Capitol! David Stork from Rambus also spoke on this topic with the same application – vein ...

Imaging Lightly: July 2011
http://imaginglightly.blogspot.com/2011_07_01_archive.html
Wednesday, July 20, 2011. I'm back home again! Last week at COSI was such good fun! Next I look forward to Frontiers in Optics in October. This year FiO is in the Bay area. It's usually a big enough meeting that plenty of people travel to make it. So it's nice to have it in sunny California! Some time back there was also the most awesome laser tag event and some cool eday demos. Young optics professionals from all over had come together to showcase all the cool and innovative stuff you can do with op...

Imaging Lightly: My work
http://imaginglightly.blogspot.com/p/my-work.html
Hey everyone. I guess I should give a short update about my own research interests here. (high time.). I graduated from the University of Rochester. I worked there with Professor James Fienup. And Professor David Williams. My thesis research was on superresolution. I used structured illumination. To obtain superresolution, did some work in retinal imaging. And some on fluorescence microscopy. I also did some application of optical sectioning/confocal imaging. I have also worked in digital holography.

Imaging Lightly: August 2011
http://imaginglightly.blogspot.com/2011_08_01_archive.html
Friday, August 12, 2011. Ideas, start-ups and Milton Chang. It’s been busy past couple of days, resulted in fewer posts. I’ve been working on a project at RII, trying to make an idea work. Some of it was in my area of expertise. Some was new to me. And some of it was completely unknown (this is research after all). After some crazy tinkering, finally it seems to work! Milton Chang is a well-known name in the optics community. He was the President/CEO of Newport. Meeting. What would he be like? Note: If y...

Imaging Lightly: Multi-aperture imaging from Brussels
http://imaginglightly.blogspot.com/2013/07/multi-aperture-imaging-from-brussels.html
Wednesday, July 10, 2013. Multi-aperture imaging from Brussels. Following up on some more multi-aperture systems at the Applied Industrial Optics. And her team from Brussels. Discussed multiple such systems that replace wide angle fisheye lenses. Their multi-channel, multi-resolution system gives less distortion and allows flexible choices in image resolution and fields of view. They combine two lens arrays in sequence, with baffles acting like channels in between. One of the designs from Heidi's team.

Imaging Lightly: Seeing is believing, unless it's AR
http://imaginglightly.blogspot.com/2013/07/seeing-is-believing-unless-its-ar.html
Thursday, July 11, 2013. Seeing is believing, unless it's AR. Freeform lens from Hong's Lab. Hong Hua from University of Arizona. Gave an exceptional invited talk on light-weight low cost wearable displays for augmented reality applications at the Applied Industrial Optics meeting. At Micro-Optical Corp, and Rolland, et al. I haven't written here about Kevin Thomson and Jannick Rolland. S talks. Parallel sessions! But do check out their websites too. some of the best work is going on these areas! The opi...
