  • Publication number: 20200060549
    Abstract: An infrared light source radiates, to an ATR prism, infrared light in entirety or part of a wavelength range with absorption wavelengths of a biological material. The ATR prism is adherable to a measurement skin. A prism vibration controller is mounted on the ATR prism and vibrates the ATR prism perpendicular to a contact surface between the ATR prism and the measurement skin. A controller causes an infrared photodetector to detect infrared light in synchronization with the vibration of the ATR prism.

  • Publication number: 20200060620
    Abstract: An infrared light source radiates infrared light. An ATR prism receives, on a first end face, the infrared light radiated from the infrared light source, causes the received infrared light to pass therethrough while repeating total reflection off a second end face and a third end face, and emits the infrared light that has passed therethrough from the third end face. An infrared photodetector detects the intensity of the infrared light emitted from the ATR prism. Strain sensors, which are contact sensors of one type, are attached to the ATR prism and configured to detect a contact state between the ATR prism and a measurement skin.

  • Patent number: 10547389
    Abstract: A timing adjuster shifts a timing between a first data-stream group and a second data-stream group in accordance with a timing setting. A data generator in first test mode generates a first test-data stream repeating 2N-bit marks and 2N-bit spaces as each of a first data stream and a third data stream, and generates a second test-data stream that is N-bit shifted from the first test-data stream, where N denotes a natural number. A first phase-difference setting and a second phase-difference setting are rendered zero. The timing adjuster adjusts the timing setting so as to maximize a detected value from a peak detection circuit.
