Abstract: An apparatus for detecting position or temperature distribution of an object has a lens which is rotated around a pyroelectric type infrared sensor to collect incident infrared ray on the sensor while scanning the incident infrared ray in a rotational direction. The optical scanning is operated also in the longitudinal direction by providing with a plurarity of lenses having different view in the longitudinal direction, the lenses being rotated sequentialy around the sensor. Further, detection of temperature of an object is conducted without using optical chopper by alternately observing the object and a standard temperature material which is arranged in a part of view, or by providing a stationary slit unit on a curved surface formed around a center axis which is the same as the rotation axis of the lens and a movable slit unit heaving the same pitch and arranged adjacent to the stationary slit unit and rotating together with the lens to intermitting the incident infrared ray.
