Pyroelectric sensing station for automatic recognition of position and orientation of objects

An object position and orientation recognizing device using pyroelectric polyvinylidene fluoride (PVF2) 16 × 16 sensor matrix is proposed in this paper. A theoretical analysis, based on a three layer sensor model (absorber-pyroelectric film-substrate), of the response of such substrated sensor to rectangular pulse thermal radiation is presented along with its experimental validation. The electronic part and the recognition operation are also briefly described. Satisfactory recognition results have been obtained from a prototype of the proposed device
