【Abstract】 For pyroelectric thin films infrared sensors, the simulation of absorptance and response characteristics has been made using optical, thermal and pyroelectric models. When the physical parameters of the multilayer system components are definite, the design of the sensor system structure has remarkble influence on the sensor performances as response to the incident infrared radiation with various wavelengths and at different modulation frequency.更多还原
