Abstract
An illumination apparatus according to the present invention includes a light source, a reflecting mirror, an optical system, and a calculator. The reflecting mirror includes a first reflector and a second reflector, and is capable, while changing a reflection angle, of reflecting and directing at an object a first divided light, the first divided light being a portion of light from the light source emitted at the first reflector. The optical system divides the light from the light source into the first divided light and a second divided light, and guides the second divided light to the second reflector. The calculator is capable of calculating the reflection angle of the reflecting mirror by receiving the second divided light reflected by the second reflector.
