Portable Microscope Uses Holograms Instead of Lens
Zothecula writes "While financial contributions are certainly a great help to health care practitioners in developing nations, one of the things that they really need is rugged, portable, low-cost medical equipment that is compatible with an often-limited local infrastructure. Several such devices are currently under development, such as a battery-powered surgical lamp, a salad-spinner-based centrifuge, and a baby-warmer that utilizes wax. UCLA is now working on another appropriate technology in the form of a small, inexpensive microscope that uses holograms instead of lenses to image what can't be seen by the human eye."
I am a physician and I work in africa sometimes. The real treat here is potentially using optics (confocal or OCT) to produce better contrast in a small package. Processing tissue for light microscopy requires a big lab; this device uses reflectance data, not transmission, making it ideal for a hunk of flesh
Generally no. Think back to HS biology, you put stuff on clear glass slides to see it. If it operated on reflective you wouldn't need the slide, just put it under the black or white base and look.
