The concave cut-outs have a radius of curvature greater than a radius of curvature of the support elements (66) and are part spherical. The spacer structure is much more resistant to high inertial and vibratory forces. Another aspect provides an etalon with two pairs of partial mirrors (12) and evacuation elements through which the cavity may be evacuated even though mirrors overlay them. In another aspect spacer element is provided with a plurality of symmetry-balancing elements, preferably having a structure and dimensions the same as or very similar to the mirrors. There is also provided access through which one or more of the bores may be evacuated through mirrors or symmetry-balancing elements overlaying them.

A sensor or receiver array includes first and second pyroelectrically active electrodes formed of polyvinylidene difluoride and separated by a spacer layer that acts to electrically separate the pyroelectric layers while keeping them close enough such that they see effectively the same vibration or background acoustic excitation while maintaining sufficient separation to ensure that they generate significant differences in their pyroelectric responses. The structure provides two distinct signals (at separate timestamps), the difference between which provides a more accurate signal.
