Title: Optical device for focus detection
Inventor: IWAKI TADAO
IPC: G02B7/28
Filed: 1982-09-24
Abstract: PURPOSE:To simplify the construction and to eliminate out of focus with easy minute adjustment, by leading reflected light to a birefringent plate and a three- split PIN photodiode and feeding its output back to a lens operating coil. CONSTITUTION:The reflected light is fed back to the lens operating coil 6 through the birefringent plate 4, the 3-split PIN photodiode 5, and a differential amplifier 8. The brirefringent plate 4 is a flat plate made of calcite cut off at a plane vertical to an axis tilted by 25-55 deg. to the optical axis and arranged so that the linearly polarized light plane of the reflected light is included in a plane including the optical axis of the birefringent plate. When a disc is focused accurately on a position of 3a, the reflected light is made incident vertically to the birefringent plate 4 and the optical path is bent in the birefringent plate 4. In rotating the disc at high speed, the disc is displaced as shown in 3b, 3c, the reflected light is not incident vertically to the birefringent plate 4, but transmitted linearly in the birefringent plate 4. The focusing state is known from the output difference of the three-split PIN photodiodes 5a, 5b. Further, the outputs of diodes 11b, 11c are compared to detect the upward/downward displacement of the disc.
