Abstract
A detection apparatus includes at least one processing unit, a light guide optical system configured to cause projected light to focus on a spatial image forming plane to form an image thereon, and a camera configured to detect an entry depth of a target object in a direction orthogonal to the spatial image forming plane and an entry position of the target object on the spatial image forming plane based on an image captured in such a manner that the spatial image forming plane is included within an angle of view, and the processing unit executes an operation associated with the entry position when the entry depth of the target object reaches a set depth.
