"This research opens an exciting new direction for camera technology with unprecedented compactness, allowing us to envision applications in atmospheric science, remote sensing, facial recognition, machine vision and more," said Capasso.  A compact and simple camera that can determine the full polarization of light has been developed by researchers in the US.  In their experiments, the researchers first transformed an ordinary laser beam into an accelerating one by reflecting the laser beam off of a spatial light modulator.  Researchers from Umeå University and Linköping University in Sweden have developed light-emitting electrochemical cells (LECs) that emit strong light at high efficiency. As such, the thin, flexible and lightweight LEC promises future and improved applications within home diagnostics, signage, illumination and healthcare.  Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons-particles of light-interact and change direction.  In materials research, chemistry, biology, and medicine, chemical bonds, and especially their dynamic behavior, determine the properties of a system. These can be examined very closely using terahertz radiation and short pulses.
