Widely tunable continuous-wave optical parametric oscillator (OPO) systems help meet the demands on holographic elements (HOEs) for many use cases, including head-up displays and augmented reality devices. The wide tuning range allows direct adjustment of replay wavelength with little to no need modification recording geometry. HOEs fabricated using these OPO in conjunction advanced photopolyme...

Method Over a one year period (April 2012-March 2013) all prehospital trauma patients attended by the doctor-paramedic LAA team who were identified as having airway compromise or an indication for any airway intervention on scene were included in a prospective observational study. The doctor paramedic team recorded any airway compromise on arrival and prior interventions carried out by ambulanc...
