Document Type and Number:
Japanese Patent JP2772777
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sun tracking device which can accurately correct a 100% photodetection state by observing the spectrum of the sunshine transmitted through the atmospheric layer surrounding the earth and photodetecting the sunshine arriving without being transmitted through the atmospheric layer. SOLUTION: This device consists of a movable reflecting mirror 13 which changes the reflection direction of the incident sunshine 16, a piezoelectric driving light splitter 19 which splits the sunshine reflected by the movable reflecting mirror 13 to a 1st optical path 17 and a 2nd optical path 18, a telescope 11 which focuses the sunshine made incident through the 1st optical path 17 to form a sun plane, a slit 15 which is arranged at the focus position of the telescope 11 and limits a spectrum observation visual field, a tracking sensor 12 which detects the incident angle of the sunshine made incident through the 2nd optical path 18, a tracking control system which controls the reflection direction of the movable reflecting mirror 13 through two-axial gimbals 13a and 13b according to the incident angle signal outputted from the tracking sensor 12, and an in-sun-plane scanning means which scans a slit image of the slit in the sun plane by changing the reflection direction of the movable reflecting mirror 13 by the tracking control system by deflecting the optical axis of the 2nd optical path 18.
