ABSTRACT:
A temperature distribution measuring device has a turnable sensor head section 1 in which a plurality of detecting sections are arranged, a shaft 2 to which the sensor head section 1 is mounted so that the array direction of the detecting sections is inclined to the axis of rotation thereof, a rotation driving motor for rotating the shaft 2, control circuit 8 for controlling the direction and speed of rotation of the rotation driving section 3, and an umbrella-shaped chopping member for intermittently blocking incident infrared beams. The device has high spatial resolution and can offer temperature resolution at low cost.
