Driving pulses from a generator 31 are supplied to the electrode surfaces 23 and 24, and an oscillator 21 sends out ultrasonic pulses through the layer 26. The driving pulses are supplied to the control terminal of a switch circuit 34 through a timer circuit 37 to turn on the electrode surfaces 24 and 25. Therefore, an oscillator 22 starts oscillating in the opposite phase to the oscillator 21, and suppresses a composite oscillation voltage greatly to eliminate piezoelectric oscillation, namely, to damp it electrically.

Abstract: PURPOSE:To enable the alteration of the spot diameter of a temperature- measuring surface without changing the magnification of lenses or the like, by arranging a pinhole plate having a pinhole smaller than the core diameter of an optical fiber on the input end face thereof. CONSTITUTION:Infrared rays from a measuring surface 1 are introduced to an input end face 2A of an optical fiber 2 with a lens 3 to be converted into an electrical signal with an infrared ray detector via the output end face or the like thereof. A pinhole plate 11 having a pinhole 10 smaller than the fiber core diameter D is provided on the input end face 2A. With such an arrangement, infrared rays incident into the optical fiber 2 are confined to those radiated through the spot diameter dS smaller than the spot diameter (d) given without any pinhole. This result will be the same as obtained by raising the magnification of the lens 3 on an apparent basis. This apparent magnification is determined by the pinhole diameter dP and the desired spot diameter dS can be obtained by altering the size of the pinhole 10. The temperature measurement within a slight range is also possible without requiring the alteration of the lens 3 and the fiber 2.
