| Abstract: | The ambient temperature variation noise and vibration noise in a pyroelectric IR detector were investigated systematically. The dependence of the specific detectivity and temperature variation noise on the load resistance was studied. In addition, the characteristics of the IR detector with complementary domain structure are discussed in this paper. |
