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.

Abstract: A position measuring device includes a light emitter, an image capturer, a first beam splitter, a first light receiver, a second light receiver, a calculator, and a controller. The first light receiver receives light that propagates along a first optical axis toward the light emitter and is reflected by the first beam splitter, and outputs a first signal. The second light receiver outputs a second signal corresponding to an intensity of light propagating along a second optical axis toward the image capturer. The controller controls the intensity of the laser light based on the second signal when a difference between the first signal and the second signal is smaller than a predetermined threshold, and performs control so that the laser light has a predetermined intensity when the difference between the first signal and the second signal is equal to or greater than the threshold.
