Control of Probe Beam Duration in Single Wavelength Monitoring of Hologram Diffraction Efficiency
This technology is a novel technique for monitoring the diffraction efficiency of Volume Holographic Elements (VHOEs) in real time. The technique works by using a shutter or chopper to periodically block one of the exposing beams during the fabrication and measuring the power of the diffracted beam using a power meter. This technique has the potential...
