Abstract
An infrared detector includes a pyroelectric element, a first amplifier, and a second amplifier. The pyroelectric element includes a first electrode formed on a first surface of a pyroelectric body, and a second electrode formed on the opposite surface. The first amplifier is connected to the first electrode, and amplifies signals induced to the first electrode. The second amplifier is connected to the second electrode, and amplifies signals induced to the second electrode.
