Fluorescent Fingerprint Tag IDs 'Hidden' Prints
Lifting latent fingerprints on knives, guns, bullet casings and other metals with higher confidence is now possible using a film of electrochromic polymers, which change colors when subjected to an electrical voltage, researchers from the Science and Technology Facilities Council’s ISIS pulsed neutron and muon source, the University of Leicester and the Institute Laue-Langevin have found. “By using the insulating properties of the fingerprints to define their unique patterns and improving the visual resolution through these color-controllable films, we can dramatically improve the accuracy of crime scene fingerprint forensics,” said professor Robert Hillman of the University of Leicester. “From the images we have produced so far, we are achieving identification with high confidence using commonly accepted standards.”

Listening to Blood Cells
Red blood cells struck with laser light generate high-frequency sound waves that Ryerson University investigators say could help to differentiate normal blood cells from abnormal ones for the diagnosis of blood-related diseases.

Transistor Works with Light, Not Electricity
An electrical charge applied to an ultrathin layer of material can change the polarization of terahertz light beams, creating the optical equivalent of an electrical transistor, its creators at Vienna University of Technology say.

SPIE Optics + Photonics is the largest interdisciplinary technical conference in North America, presenting the latest research and technologies in solar, nano, optics, photonics and space optics. The conference’s four symposia (Nanoscience + Engineering, Solar Energy + Technology, Organic Photonics + Electronics, and Optical Engineering + Applications) will offer more than 3200 presentations, including plenary and featured talks on topics such as metamaterials for molded optical wavefronts, asteroid-tracking and collision-mitigation, Kepler’s search for Earthlike planets and nanoparticle technology to convert solar energy directly into saturated steam for sterilizing tools and waste. The show also will include more than 40 professional development courses, poster sessions, panel discussions and a tribute to H. John Caulfield.

FEATURED VIDEO
Princeton Instruments - IsoPlane SCT Spectrograph
Through its use of proprietary optics and a novel optomechanical design, the IsoPlane SCT (Schmidt-Czerny-Turner) improves upon the traditional Czerny-Turner-type spectrograph, which, despite being limited by the age-old design’s inherent image aberrations, is still the most commonly used research instrument in dispersive optical spectroscopy. Its novel optical design provides the ability to use the full spatial extent of their detector without loss of spectral or spatial resolution, and it provides the only major innovation to the design of research-grade imaging spectrographs in more than 20 years.
