title: Fabrication of an integrated holographic imaging element for a three-dimensional eye-gaze detection system.
abstract: We evaluate the imaging characteristics of an integrated optical imaging element that is used to obtain images from opposite directions in one imaging sensor for a three-dimensional eye-gaze detection system. The element consists of a transmission-type holographic imaging element, a reflection-type holographic imaging element, and a noise reduction filter. In the evaluation of the imaging characteristics, modulation transfer functions of both the reflection-type and the transmission-type holographic imaging elements are evaluated. Results indicate that both holographic imaging elements have enough resolution, even under white-light illumination conditions, for eye-gaze detection. We also demonstrate the simultaneous detection of images by an artificial eye and objects by using the integrated element under white light or sunlight.
