Title: Distance measuring circuit
Inventor: MIYASAKA AKIRA
IPC: H04B7/212
Filed: 1983-03-16
Abstract: PURPOSE:To measure an error distance at a high speed after comparing a reception position with a standard position by calculating and holding the shift between the burst reception position of own station and the standard position of the burst returned from a satellite station of the own station on the basis of a reference burst returned from the satellite station for each pescribed symbol. CONSTITUTION:A standard position extracting circuit 1 of a distance measuring circuit detects a standard position from the reception data of a reference station and then produces a standard position signal. At the same time, an own station burst position extracting circuit 2 produces an own station burst position signal showing the own station burst position from the reception data. Furthermore a standard position generating circuit 3 generates a standard position signal of the own station burst from the standard position signal given from the circuit 1. The difference is measured between the standard position given from the circuit 3 and the burst position received from the circuit 2 and then held at an error measuring circuit 4. Then a comparison position generating circuit 5 produces a comparison position signal having a shift from the standard position by an amount equivalent to the distance measurement data. A phase comparator 6 compares the outputs of the circuits 4 and 5 with each other. Thus an error distance between a ground station and a satellite is measured with high accuracy.

Abstract: PURPOSE:To omit a coma aberration correcting optical element, to reduce the number of parts and to easily assemble the parts by forming a wave front phase correcting layer for correcting a coma aberration on the surface of an optical element for generating astigmatism. CONSTITUTION:The wave front phase correcting layer 1b for correcting the coma aberration of the plate-like optical element (half mirror) 1 for generating astigmatism by passing a focus error detecting reflected beam from a recording medium is formed on the surface of the optical element 1.
