摘要： A self-delayed homodyne interferometer includes light source unit, a splitting unit, an interference signal acquisition unit, a scattered light intensity acquisition unit, and a signal processing unit. The light source unit generates probe light. The splitting unit splits into two branches, Brillouin backscattered light occurring in an optical fiber to be measured with the probe light. The acquisition unit receives scattered light of one branch, and uses a self-delayed homodyne interferometer to generate an interference signal. The acquisition unit receives scattered light of the other branch, and acquires intensity of the scattered light. The signal processing unit separates and acquires a frequency shift amount from the intensity of the interference signal, and strain and temperature change from the intensity of the scattered light. The acquisition unit can change a phase of the scattered light of the one of the two branches.

摘要： A medium storage box includes a guide member and a liquid spraying mechanism. The guide member forms a stacking space for a medium. The liquid spraying mechanism sprays a liquid from a liquid spraying nozzle. The liquid spraying nozzle has a pipe section through which liquid flows, a first liquid spray hole and a second liquid spray hole. The first liquid spray hole sprays liquid in a direction that intersects an extension direction of the pipe section at substantially a right angle. The second liquid spray hole sprays liquid in a direction that is approximately the extension direction of the pipe section.

摘要： The authentication system comprises: the authentication side unit configured to include the intensity modulated weak light source, the first reading unit, the decrypting unit, and the determining unit; and the client side unit configured to include the detecting unit, the second reading unit, and the encrypting unit. The intensity modulated weak light source generates intensity modulated weak light. The first reading unit reads the transmission time information. The detecting unit detects the intensity modulated weak light, and records the detected time in the second storage medium as reception time information. The encrypting unit encrypts all or part of the reception time information and generates encrypted information. The decrypting unit decrypts the encrypted information, and acquires all or part of the reception time information. The determining unit acquires a number of coincidence events and a number of elements of the all or part of the reception time information, generates determination information including information indicating approval when both of the number of coincidence events and the number of elements are within a range of a set value which is set in advance, and generates determination information including information indicating a denial in the other cases.
