New Imaging Technology Takes Cues From Astronomy And Ophthalmology To Make Microscope Images Sharper
2014-04-14 14:55:46

Howard Hughes Medical Institute The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology developed at the Howard Hughes Medical Institute's Janelia Farm Research Campus rapidly corrects for these distortions and sharpens high-resolution images over large volumes of tissue. The approach,...

Nanopositioning specialist PI (Physik Instrumente) LP – offers a new large aperture type nanopositioning system consisting of a digital controller and precision positioning stage based on piezo drives and flexure guides. The system is designed for imaging, surface metrology and microscopy applications. Auburn, MA (PRWEB) February 26, 2014 PI’s new P-736.ZR Large Aperture piezo nanopositioning stages are optimized for high resolution and very fast step and settle. They are designed...

Engineers Show How To Make Cost-effective, Ultra-high-performance Microscopes
2013-07-29 14:44:20

California Institute of Technology Engineers at the California Institute of Technology (Caltech) have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope. Such a system could greatly improve the efficiency of digital pathology, in which specialists need to review large numbers of tissue samples. By making it possible to produce robust microscopes at low cost,...

'Super-resolution' Microscope Used To See Nanostructures
2013-04-29 16:09:39

Purdue University Researchers have found a way to see synthetic nanostructures and molecules using a new type of super-resolution optical microscopy that does not require fluorescent dyes, representing a practical tool for biomedical and nanotechnology research. "Super-resolution optical microscopy has opened a new window into the nanoscopic world," said Ji-Xin Cheng, an associate professor of biomedical engineering and chemistry at Purdue University. Conventional optical microscopes...

Michigan Tech Researcher Nears Creation Of Superlens
2012-01-09 04:37:13

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones. No one has yet made a superlens, also known as a perfect lens, though people are trying. Optical lenses are limited by the nature of light, the so-called diffraction limit, so even the best won´t usually let us see objects smaller than 200 nanometers across, about...

Image 1 - iPhone Transformed Into  High-quality Medical Imaging Device
2011-10-03 09:49:20

Advanced, life-saving capabilities become a simple add-on to handheld technology you already use In a feat of technology tweaking that would rival MacGyver, a team of researchers from the University of California, Davis has transformed everyday iPhones into medical-quality imaging and chemical detection devices. With materials that cost about as much as a typical app, the decked-out smartphones are able to use their heightened senses to perform detailed microscopy and spectroscopy. The...

Portable Microscope Detects Bacteria Using Holograms
2011-09-02 04:39:25

  Engineers at UCLA have developed an inexpensive, portable, lensless microscope. This microscope may find its use in improving health care and sanitation in areas where sophisticated equipment is unavailable or unusable. The details of the microscope were published in the open-source journal Biomedical Optics Express. BBC News reports that the microscope uses lasers and sophisticated mathematics, instead of lenses, to develop a holographic image that identifies bacteria or...

Device described in Biomedical Optics Express could be used for field diagnostics in developing countries, testing of water quality, food contamination To serve remote areas of the world, doctors, nurses and field workers need equipment that is portable, versatile, and relatively inexpensive. Now researchers at the University of California at Los Angeles (UCLA) have built a compact, light-weight, dual-mode microscope that uses holograms instead of lenses. The team describes the new device...
