摘要： A polymer pyroelectric infrared sensor having an improved sensitivity and an improved heat resistance is formed by disposing a pyroelectric film having electrodes for taking out a pyroelectric output on both sides so as to face a window for introducing infrared rays. The pyroelectric film comprises a pyroelectric film of vinylidene fluoride copolymer having a crystallinity of 60% or more and a relative dielectric constant of 10 or below at 25.degree. C. and in a low frequency region of 0.1-10 Hz.

摘要： A pyroelectric infrared detector or infrared ray receiving element comprising a plurality of pyroelectric operating areas, utilizing one of the operating areas as an infrared radiation detection area having a light-transmissive surface electrode. The electrical signal produced in the signal detection area is compensated by an electrical signal produced in another pyroelectric operating area having a light-reflective surface electrode. Temperature drift and noise due to vibration are drastically reduced through the compensation.
