HOLOGRAPHIC OPTICAL PICKUP DEVICE, HOLOGRAPHIC DEVICE, AND HIGH-SPEED IMAGE PICKUP DEVICE

摘要

The purpose of the present invention is to provide a holographic optical pickup device capable of performing high-speed reproduction, a holographic device, and a high-speed image pickup device. Disclosed is an optical pickup device that reproduces information from a recording medium having an interference pattern of signal light and reference light recorded thereon as a hologram. The optical pickup device is characterized in being provided with: a laser output section that outputs the reference light; a lens through which the reference light outputted from the laser output section is inputted to an optical information recording medium; and a detection optical section that detects diffracted reproducing light from the optical information recording medium on the basis of the reference light. The optical pickup device is also characterized in that the detection optical section includes a plurality of image pickup elements.
