Abstract

PURPOSE:To simplify construction by providing a shutter between an object to be measured and an infrared ray sensor, repeating different incident time and shutting time at roughly constant periods, processing output signals in synchronization with these and determining phase differences. CONSTITUTION:The infrared rays 3 from a body 2 to be measured are detected with a sensor 7 through a window 4 then through a reflection plate 5. En route of this, a disc 8 having notched parts B is rotated by a motor 8 to intermit the infrared rays 3. The angle that the parts B and the disc part A assume with respect to the center O is set at thetaA>thetaB. The energy proportional to the biquadratic of the temp. To of the object 2 and the temp. Tc of the part A functioning as a shutter plate inputs to the sensor 7. The output of the sensor 7 is processed with an amplifier having filter characteristics, and the AC signal shown having a correlation with T0<4>, Tc<4> is obtained. t1 is the time when the object to be measured is viewed and t2 is the time when the part A is viewed. The t1 is a temp. measuring time, and the output between the t1 is rectified by taking synchronization with the rotation of the disc 8. Thereby, the temp. of the object to be measured is measured.
