Advance in light-based computing shows capabilities for future smart cameras - EurekAlert
<p>Optical computing research aims to produce energy-efficient technologies that use particles of light, called photons, in ways conceptually similar to how electronic computers use electrons.</p> <p>One obstacle to realizing optical computers is that using photons for nonlinear operations —needed to process information — usually requires high-powered lasers, yet responds slowly or uses photons inefficiently.</p> <p>A UCLA team has invented a transparent device that offers nonlinear operation under low-power ambient light, and combined it with a smartphone camera for glare reduction — an example of numerous applications this technology could enable.</p>
