Title: Phase detector for pseudo noise code
Inventor: UEKI BUNYA
IPC: H04B1/7075
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To highly precisely detect the phase of a pseudo noise code without being affected by a multi-pass by detecting the real phase of the pseudo noise code from the shift of an estimated code phase obtained in a state where spacing differs. SOLUTION: When a reception signal is not affected by a multi-pass, the curves of correlation are symmetric to the center line. The values of an estimated code phase Q in code tracking -1 and an estimated code phase R in code tracking -2 become the same. When the curves of correlation becomes symmetric by the influence of a multi-pass component, two code tracking loops cannot set the position of the highest correlation to be an estimated code and an error occurs. The error is proportional to the spacing of EARLY and LATE. When the estimated code phase obtained in spacing S1 is set to be Q, the estimated code phase obtained in S2 to be R and the phase of the highest correlation value to be P, P becomes the value expressed as P-(S2Q-S1R)/(S2-S1). The estimated code phase P from which the influence of the multi-pass is removed can be obtained.

Title: Optical information reader
Inventor: YASUKAWA KAORU
IPC: G11B7/08
Filed: 1982-11-22
Abstract: PURPOSE:To avoid the revolution of a beam splitter itself by providing a laser light source, a beam splitter, a photodetecting element, etc. at the fixed stage side and providing an objective lens and an optical system which leads the laser light to the objective lens to a mobile stage that moves in the radius direction of a disk. CONSTITUTION:If it is supposed that a mobile stage 2 revolves in response to the shift of a disk 1 toward its radius direction, it is sufficient to think about the revolution of an objective lens 14a since only said objective lens is set on the stae 2. If the lens 14a turns around a center point P by theta as shown by broken lines for convenience, the image forming position a' of the laser light on the disk 1 set by an objective lens 14a' after revolution goes away from the image forming position (a) set with no revolution by a focal distance of f1tantheta, where f1 shows the focal distance of the lens 14a (14a'). However, a beam splitter 10, a condenser lens 15 and a photodetecting element 16 are set on a fixed stage 3 and consequently have no revolution. Therefore the polarization separating surface 10a of the splitter 10 also has no revolution. Thus the reflected luminous flux 17a' sent from the surface 10a is made correctly incident to a point (b) of the element 16 as in the case where the mobile stage 2 has no revolution.
