Abstract: An optical detection system for measuring a refractive index of a liquid analyte comprising a light transmitting assembly fiber, which includes a single-mode fiber, an optical fiber sensing module and a multi-mode fiber. The optical detection system is configured to emit a coherent light beam to one end of the assembly fiber; and a detector is configured to capture a specklegram from an exit end of the assembly fiber. When the optical detection system is in operation, the optical fiber sensing module is configured to be submerged into the liquid analyte. By analyzing the correlation between the specklegram corresponding to the liquid analyte and the reference specklegram, the refractive index of the liquid analyte can be obtained.

Abstract: A vibration detection system comprises a light source, a biconical tapered fiber comprising a biconical fiber taper and a detector is disclosed. The emission light emitted by the light source is directed to the biconical tapered fiber in one side. A detector is coupled to the other end of the biconical tapered fiber to measure the intensity of the light passing through. When the biconical tapered fiber is exposed to an external vibration, the biconical fiber taper deforms and modulates the light intensity accordingly. The received signal is then fed to the microcomputer to determine the amplitude and frequency of the external vibration. A method of vibration detection is also disclosed.

Abstract: An imaging device that includes a control unit is provided. The control unit switches between a day mode and a night mode. In the day mode, image capture is performed while an infrared cut filter is placed on an optical path, and in the night mode, image capture is performed while the infrared cut filter is removed from the optical path. Immediately after shifting from the day mode to the night mode, in the night mode, as the amount of incident light decreases, the control unit increases an irradiation intensity of an infrared irradiation portion from zero while a gain is maintained at a first gain value. When the amount of the incident light further decreases after the irradiation intensity reaches a maximum, the control portion increases the gain from the first gain value.
