<p>PROBLEM TO BE SOLVED: To highly accurately measure magnitude of a fluctuation of light waves, relation with wind velocity, movement in time, variation in frequency of the fluctuation or the like by placing a pair of thermosensitive elements distantly to constitute two sides of a bridge. SOLUTION: The fluctuation measuring apparatus comprises a thermosensitive element bridge-type detector (platinum wire bridge), a micro signal DC amplifier (60 db amplifier), a differential amplifier (RMSOP), an output indicator (recorder) or the like. The thermosensitive element bridge-type detector comprises a pair of thermosensitive elements placed at a predetermined distance to constitute two sides, while two reference fixed resistors having predetermined electric resistance are used to constitute two remaining sides. A metallic wire used in each of the thermosensitive elements contains a platinum material which exhibits desired response speed and response sensitivity to a temperature fluctuation of atmospheric disturbance. The measuring apparatus can continuously observe a phenomenon of a fluctuation in an atmosphere.</p> |
