ABSTRACT:
A temperature distribution measurement apparatus has an infrared array sensor that comprises a pyroelectric substrate with infrared ray detecting electrodes, a focusing member comprising an infrared lens for focusing incident infrared rays on the infrared array sensor, a cylindrical chopping member for intermittently shielding incident infrared rays from the plurality of detector elements and a driving member for continuously rotating a rotating member which includes the infrared array sensor. The temperature distribution measurement apparatus combined with computational means and detector means is applied to determine number, position, and movements of persons in a space.
