Abstract: A curve sensor universally applicable to even a curving measurement target having a relatively small diameter is provided. A curve sensor to measure the curving of a curving measurement target includes a light supply unit which guides light, a curve measurement unit which includes a curved state detection unit and which measures the curved state of the measurement target by the change in the amount of light output through the curved state detection unit, a light transmission unit which transmits the light from the light supply unit to the curve measurement unit and a holding portion which holds the light supply unit and the curve measurement unit at predetermined positions on the measurement target.

Abstract: An endoscope includes a sensor that can detect a conductive member. Based on a detection result of the conductive member by the sensor, the endoscope can switch between a normal operation mode and an energy-saving operation mode in which power consumption is smaller than power consumption in the normal operation mode.

Abstract: An optical apparatus having a holding portion and a tubular portion further includes a light source, a light guide which is formed of a medium having a refractive index higher than 1, and an optical converting portion. The light guide has a first light guiding area having an incidence end surface and a second light guiding area having an exit end surface. A diameter of the incidence end surface is larger than a diameter of the exit end surface, and at least a part of the second light guiding area is included in the tubular portion.

Abstract: A light radiating device includes an optical element held at a desired position by a holder and configured to exhibit desired optical performance based on incoming light entered at the desired position, a detector configured to detect an amount of positional deviation of the optical element relative to the desired position, and a discrimination unit configured to discriminate whether the light radiating device is in a normal state or an abnormal state based on the detected amount of positional deviation. The normal state is a state where the optical element exhibits the desired optical performance by being disposed at the desired position. The abnormal state is a state where the optical element is disposed at a position deviating from the desired position.
