ANALYTICAL SOLUTION FOR THE RESPONSE OF A FERROELECTRIC THIN FILM TO INFRARED RADIATION

摘要：

Response of a micro-bolometer pixel to an infrared radiation is analyzed.The pixel structure is modeled as a composite laminate thin plate.Its middle ply is a BST ferroelectric thin film.Its top surface is covered with platinum infrared absorber,receiving infrared radiation pulses,while the bottom surface is deposited with platinum.Meanwhile both surfaces are a pair of electrodes.The thermal-electric-mechanical coupling governing equations are solved in a form of Fourier series.Results of the displacement,temperature variation and electric output signals of the pixel are obtained and compared with experimental data.
