Pyroelectric PVDF detectors have been designed and elaborated from a biaxially oriented material which is poled through the standard method (electric field-temperature). A model of this process based on the ARRHENIUS law has been derived. Increase of the properties of the detector is achieved by the deposition of an absorbing layer on top, by using a me-chanical attachment allowing shocks and vibrations absorption to reduce the piezoelectric effects and by matching the detector with the following preamplifier. Approach to a linear array is presented.
