摘要： In an FBG (Fiber Bragg Grating) sensor, a stress direction converter includes a flat portion to which stresses are applied from the exterior, and stress transmitting sections that are bridged from the flat portion to an optical fiber cable. An inclined portion of the optical fiber cable, through which reflected light reflected by gratings is transmitted, is disposed along an inclined section that makes up one of the stress transmitting sections.

摘要： An FBG (Fiber Bragg Grating) sensor is equipped with a plurality of stress detection sensors made up from optical fibers in which gratings that reflect light of a specified wavelength are arrayed, and a stress direction converter that converts stresses applied from the exterior into stresses of a direction in which the gratings are arrayed, and which transmits the stresses to each of the gratings. Consequently, the stress direction converter can transmit stresses, which are applied from a body, to a plurality of gratings.

摘要： An optical sensor circuit has a photodiode PD, a MOS transistor Q1, a voltage controller 13 which supplies a gate voltage and a drain voltage to the transistor, etc. The voltage controller includes initial setting means 15. In the initial setting means, an electrostatic capacitance element of the photodiode is charged/discharged while setting a gate voltage of the transistor Q1 to a high gate voltage value VgH, only for a predetermined time period, and setting a drain voltage to a low drain voltage value VdL, only for a predetermined time period. Thereafter, the drain voltage is set to VdH, and, after elapse of a predetermined time period, the gate voltage is set to VgL. VgH, VdH, and VdL satisfy relational expressions of “VgH−VdH Vth where Vth: a threshold voltage of the MOS transistor Q1”.
