摘要： A filter control apparatus which controls a frequency variable filter capable of changing a transmission band width by controlling a capacitance of at least a portion of a plurality of voltage variable capacitors connected in series and parallel to a resonator has an input unit, and a filter control circuit. The input unit inputs a reference signal with a predetermined reference frequency to the frequency variable filter. The filter control circuit controls a center frequency and the transmission band width of the frequency variable filter by detecting a phase change generated when the reference signal passes through the frequency variable filter and by variably controlling the capacitance of at least a portion of the voltage variable capacitor by using a direct voltage in proportion to the phase change.

摘要： The present invention provides an infrared detection element having a single-crystalline base layer 3 with a thickness of 50 nm to 10 μm having a principal surface, a first electrode layer 4 formed on the principal surface of the single-crystalline base layer 3, a ferroelectric layer 5 which is formed on the first electrode layer 4 and is composed of a single-crystalline layer or a unidirectioally oriented layer. Distortion of the single-crystalline layer or a unidirectioally oriented layer in a surface parallel to the principal surface of the single-crystalline base layer 3 is elastically constrained by the single-crystalline base layer 3. The infrared detection element further has a second electrode layer 6 formed on the ferroelectric layer 5. An amount of charge is changed by changes in temperature caused by irradiation of infrared light to the ferroelectric layer 5. The amount of the charge is detected from the first and the second electrode layer4, 6. With the infrared detection element, an accurate temperature measurement is possible even in the neighborhood of the Curie temperature due to a discontinuous primary phase transition.
