摘要： PURPOSE:To measure the fast change of light to be measured with high resolving power by recording the light to be measured on an optical recording medium with high resolving power. CONSTITUTION:The intensity of light 1 to be measured is adjusted by a light intensity modulator 2 so that light induced reaction is properly brought about and the light to be measured is deflected by a light deflector 3 so as to be incident on the arbitrary region of an optical recording medium. The light spectrum of the light 1 to be measured during the period when the recording medium is irradiated with the light 1 to be measured at the incident position is recorded on the optical recording medium 4 by light induced reaction. The reproduction of the recorded light spectrum is performed by allowing reading light controlled so as not to newly bring about light induced reaction to be incident on the recording region of the optical recording medium 4 by a light modulator 6. The reading light 5 is modulated by the absorbing characteristics in the recording region to reproduce the recorded light spectrum 1 of the light 1 to be measured.

摘要： PURPOSE:To attain high information recording density based upon multiplex recording by guiding optical beams with plural different wavelengths to a fixed optical path by means of an optical element having reflective index wavelength dispersing property and concentrating the beams into a medium. CONSTITUTION:Recording, data erasing, focusing/tracking, and focusing wavelength variable lasers LD1-LD4 are arranged on an optical head 10. These lasers LD1-LD4 emit laser beams having respectively different wavelengths. A dichroic mirror (DM) 111 transmits only the wavelength band light of the LD1 and reflects beams having other wavelength bands. Respective DMs 112-114 reflect only the beams of wavelengths corresponding to the LD2-LD4 and transmit other beams. Thereby, all beams are made incident upon a deflecting beam splitter 105 and condensed into the medium 5. The emitted beams and reflected beams from the medium 5 are simultaneously and dispersely condensed into different positions corresponding to respective wavelengths by a hologram lens 108. Said constitution makes it possible to attain high information recording density.

摘要： PURPOSE:To enable the multiple recording of information on a wavelength level, by constituting built-up films so that absorption wavelengths of light are mutually different between two arbitrary built-up films and irradiating a recording medium with light of which the wavelength is variable to perform at least one of the writing and reading of information. CONSTITUTION:When a recording medium 5 consisting of built-up films L1-Ln (n is a natural number), all of which have different absorption wavelengths, each obtained by building up a monomolecular film containing org. coloring matter in the molecule thereof is formed on a substrate 4, the built-up films have different absorption wavelengths lambda1-lambdan6. When writing is performed to the recording medium 5 using layer beam as light 7 of which the wavelength is made variable with respect to the recording medium 5 wherein the built-up films L1-Ln of monomolecular films take a J-state, only the built-up film wherein the wavelength lambda is equal to the absorption wavelength thereof can change to a new J*state 8. By using the presence and absence of the change in the absorption spectrum characteristic of the built-up film as signals of binary codes of 0, 1, (n) informations can be written to one recording point on a wavelength level.

摘要： PURPOSE:To reduce the thickness of the device considerably by arranging a semiconductor electrode for absorbing the light and an electrode paired with said semiconductor electrode on the same face of a common insulative substrate then immersing in the electrolytic solution. CONSTITUTION:It is comprised of a semiconductor 1a, a metal 1b forming the ohmic contact with said semiconductor 1a, conductive adhesives 1c and an insulator 1d, where the semiconductor electrode 1 for absorbing the light and the electrode 2 to be paired are approached to the same face of the insulative common substrate 6 and adhered then contained in a container 5 filled with the electrolytic solution 4 containing the electrolytic solution or the reversible oxidation/reduction system thus to produce a light energy converter. Since the electrolytic solution 4 is placed between the faces of the container 5 where both electrodes 1, 2 are facing, the thickness of the device can be reduced considerably.
