<p>In order to reduce microphony due to the piezoelectric nature of a pyroelectric element (9) in a pyroelectric detector, the detector comprises one or more flexible films resiliently supporting the element (9) and two electrical connections thereto each comprising an electrically conductive layer (6,8) on the film(s). There are suitably two films with the element (9) therebetween. The films are secured to one another around the element (9) by an adhesive, thereby urging the films against the element (9) to hold it in position and maintain the electrical connections.</p> |
