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.
