    • PURPOSE:To obtain the optical recording medium which allows an increase in capacity by using a material which is changed in light transmittance according to the wavelengths of irradiating light as a recording film. CONSTITUTION:The recording film 2 which is changed in the light transmittance according to a physical or chemical change by photoirradiation is formed on a substrate 1. Azobenzene, rhodopsin, etc., which have a wide absorption band in visible to UV regions and are changed in the quantum yield of a photochemical reaction by changing the wavelength of the irradiating light are used as the material of the recording film 2. The method for forming this material on the substrate 1 includes a vapor deposition method, LB method, etc. The light source to be used for optical recording is preferably a monochromatic light source which can change wavelengths within the range of the absorption band of the recording film 2. A wavelength variable dye laser 3, etc., are preferably used as this light source. The recording of information is executed by focusing the light from the light source to a beam spot of several to several hundred mum and irradiating the recording medium with beam spot under on-off control. The reading out of the information is executed by using monitor light having the spot diameter equiv. to the spot diameter of the incident light and reading out the change in the intensity of the light absorption as the information.

    • PROBLEM TO BE SOLVED: To provide a solid-state imaging device for thermally resetting and also removing 1/f noise and a variation in each fixed pattern pixel.
      SOLUTION: The solid-state imaging device includes: a pixel 3 thermally isolated from a semiconductor substrate; a constant current source 60; a signal line 6 for transmitting voltage of constant current flowing in the pixel; a thermally conductive switch changing over to either the first state where the pixel is thermally isolated from the semiconductor substrate by the other end coming into contact with the substrate or the second state where the pixel is thermally short-circuited with the semiconductor substrate by the other end coming into contact with the pixel; and a signal detection part serving as the signal detection part 7 capacitively coupled to the signal line, which holds reference voltage (Vcl) depending on a signal (Vsl=Vdd-Vd0+dVsh+dV) on the signal line in the first state, and detects second voltage (Vcl-Vd'-dVsh') with a voltage component (dV') corresponding to incident light subtracted from the reference voltage in the second state.

    • PROBLEM TO BE SOLVED: To provide a simple and inexpensive electromagnetic wave sensor selectively and highly sensitively detecting only the millimetric waves and the submillimetric waves of prescribed frequencies, and to provide an imaging element, and an imaging device. SOLUTION: This electromagnetic wave sensor 100 is formed so that spaces of openings between a plurality of antenna elements 121 are smaller than the wavelengths of infrared light. A capacitor electrically, formed out of openings between the plurality of antenna elements, and an electrical resistance part 111 together form a parallel circuit electrically connected to an antenna part 120. The plurality of antenna elements are formed so that impedance matching is obtained for the antenna part with the parallel circuit as to electromagnetic waves having the prescribed frequencies, while impedance matching is not obtained with respect to the higher harmonics of the electromagnetic waves having the prescribed frequencies.
