Abstract

The structure for a mask applied to a detection face of a dual type pyroelectric sensor for improving detection sensitivity of moving bodies comprises a sheet portion obstructing infrared light and an aperture pattern made from through holes formed in the sheet portion. Using the direction of disposition of the two pyroelectric elements of the pyroelectric sensor on the detection face as the x-direction and the direction perpendicular to the x-direction on the detection face as the y-direction the aperture pattern is formed so that ratio of the infrared light irradiation range with respect to the two pyroelectric elements changes in accordance with movement of a moving body in the x-direction and y-direction respectively.
