P(Vdf-Trfe) Copolymer Sensor For Passive Ir Detection In Automotives
SENSORS AND ACTUATORS A-PHYSICAL(1995)
摘要
The feasibility and the limits of pyroelectric infrared (IR) detection are evaluated using a radiometric chain model and the optimal structure of the sensor is determined by a one-dimensional thermal model. Sample detectors are then fabricated and characterized. The best structures obtained show a sensitivity of 5.41 V W-1 and a detectivity of 1.33 10(9) cm Hz(1/2) W-1 Finally the good operation of a rotating IR passive pyroelectric detector is experimentally demonstrated.
