．． a2 is a perspective view of an example of the structure of the pyro-detecting element of the present invention, showing the front and back sides; b is a structure in which the pyroelectric material is polarized in a single direction; b' is a structure in which the polarization directions of El and E2 are opposite The electrical connection pattern when oriented is c, d is c4
A plan view and a longitudinal cross-sectional view of the case when it is stored in a housing are shown. 21: Housing, 22: Open window, 23: Thin plate made of pyroelectric material, P, P': Upper and lower central portions for connecting front and back electrodes, E□: Incident light sensing functional element,
E2: Functional element for temperature compensation. Figure 3a shows typical incident light sensing elements E of the present invention.
The arrangement relationship between the element E 1 and the element E 2 having a temperature compensation function arranged at a position not irradiated with incident light is shown in the case where a uniformly polarized pyroelectric thin plate is used. same a'
In addition, b' shows the electrode structure when the polarization direction of each element is reversed. 22: Represents an aperture window.
