Abstract
Volume holographic optical element (VHOE) for imaging under white light illumination is integrated with imaging elements and background noise reduction filter. An integrated VHOE and the band pass filter which is optimized to the VHOE can develop the optical setup for a wearable eye-gaze detection system. An integrated VHOE is fabricated in photopolymer and then the effects of noise reduction filters as a function of the direction of the incident plane wave into an image sensor are evaluated. Experimental results show that the background noise reduction filter should be designed to reduce the incident light with wide direction of the transmitted light.
