I came upon this in one of my classes from research done by a student. This has been developed by an optical researcher at UCLA. The technology is known as "Lensless Ultra-wide-field Cell monitoring Array platform based on Shadow imaging" (LUCAS). The process uses an imaging chip and analyzes the diffraction pattern of the cells in the image. They have produced a cell phone that can image a blood sample and do cell counts. The interesting thing for astronomy may be the analytical algorithims that are being used on the image. It is a the very least a fascinating technology. The website below is a news release on the technology for UCLA. http://newsroom.ucla.edu/portal/ucla/cell-phone-prototype-of-lensless-77054.aspx David Shafer -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
