Abstract
A radiation detection arrangement is described using a layer of pyroelectric material such as polyvinylidene fluoride positioned between two electrodes. One electrode has a radiation-reflecting front surface and is coated with material having selected radiation absorbing characteristics. This material absorbs radiation lying within a predetermined wavelength band and this therefore heats the material and produces an electrical output. Radiation lying outside the absorption band of material is unabsorbed and is reflected by the reflecting surface. No heating takes place and no corresponding electrical output is produced. A radiation-selective detector is therefore produced without the need for optical filters.
