Abstract

PURPOSE:To obtain a miniature and inexpensive pyroelectric temperature sensor which supplies infrared rays to a pyroelectric material intermittently and then detects them as an alternating-current output, by sliding glass fiber radiated with infrared rays by a reciprocating driver. CONSTITUTION:Pyroelectirc material 6 with electrodes 7 and 7' formed on both sides is arranged in shield body 1 and through glass fiber 9 whose one terminal is connected to window 2 of shield body 1 while the other (free terminal) is moved vertically by reciprocating driver 11 through connecting rod 10, infrared rays are led in and caused to strike pyroelectric material 6. Supplied infrared rays strike intermittently pyroelectric material 6 through the vertical movement of the glass fiber to generate an alternating-current pyroelectric current, which is detected by detection circuit 8 to measure the quantity of incident infrared rays. As the above- mentioned reciprocating driver, an electromagnetic vibrator, bimorph piezoelectric vibrator, etc., can be used to obtain a miniature and inexpensive unit.
