Abstract: An inspection data management system includes a terminal device and a management device that is communicable with the terminal device and is managed by a third party other than an inspector who performs a gas inspection of a gas production facility and a manager of the gas production facility. The terminal device includes an image data acquisition unit that acquires image data obtained by imaging of the gas production facility and an inspection data generation and transmission unit that generates inspection data related to the gas inspection for the gas production facility based on the image data acquired by the image data acquisition unit and transmits the generated inspection data to the management device. The management device includes an inspection data reception unit that receives the inspection data transmitted from the inspection data generation and transmission unit and an inspection data storage unit that stores the inspection data received by the inspection data reception unit.

Abstract: A laser optical device, having: a laser light emitting section to emit laser signal light modulated by information; a laser light receiving section to receive the laser signal light emitted from the laser light emitting section; a light condensing optical unit to conduct the laser signal light emitted from the laser light emitting section to the laser light receiving section; an actuator to move the light condensing optical unit; a light intensity detecting section to detect an intensity of the laser signal light conducted to the laser light receiving section; and a control section to control drive of the actuator so as to align the laser signal light conducted by the light condensing optical unit to the laser light receiving section; wherein the control section drives the actuator in a predetermined period which synchronizes with a predetermined signal included in the laser signal light.
