摘要： An improved optical encoder uses an optical pick-up unit that provides for degrees of freedom in the tracking and focus axes that are unavailable in conventional optical encoders thereby improving the encoders' performance. In an embodiment the encoder employs an optical disc marked with pits and lands which may be arranged in a spiral pattern. The optical disc is mounted on the shaft whose motion is to be monitored by the optical encoder. The encoder may be arranged to read the markings on the optical disc using the three-beam pickup method.

摘要： Disclosed herein is an optical pickup device for optical disks having different track pitches. The optical pickup device performs tracking servo follow-up using the diffraction patterns of the side regions of a beam reflected and diffracted from an optical disk where a tracking error offset attributable to the left or right shift of an object lens is minimized, and performs focus servo follow-up using the diffraction pattern of a center region of the diffracted beam. Accordingly, the present invention performs tracking servo follow-up using the diffraction patterns of the side regions of a light distribution, in which a tracking error offset attributable to the left or right shift of an object lens is minimized, so that the present invention has an effect in that a correct FES/TES for optical disks having different track pitches can be detected.

摘要： The present invention relates to a holographic storage device and method for simultaneously recording and reading on two sides, and pertains to the technical field of optical holographic storage. The device and method disclosed in the present invention use a characteristic that orthogonal light would not interfere with each other and a Bragg selectivity characteristic for holographic storage, and use two optical heads to constitute two interference fields orthogonal in polarization directions on two sides of a same position of a holographic storage medium, so as to perform two-path simultaneous recording and reading on a hologram. The device and method provided in the present invention implement two-path parallel recording and reading of holographic storage, and combine shift multiplexing and circumferential rotation multiplexing, thereby improving the speed of an information data recording and reading process while increasing a capacity of the holographic storage.
