An electromagnetic (EM) wave detection apparatus includes an irradiator that emits EM waves and a reflector that changes an irradiation position of the EM waves on an object by changing a direction of the emitted EM waves. A separation unit separates EM waves incident thereon to propagate the EM waves in first and second directions. A first detector detects the EM waves in the first direction. A switch includes plural switching elements that can switch between first and second states. EM waves in the second direction are caused to propagate in a third direction in the first state and caused to propagate in a fourth direction in the second state. A second detector detects the EM waves in the third direction. The switch switches each of the plurality of switching elements between the first and second states according to the direction in which the reflector reflects the EM waves.

The first detector () includes detection elements. The detection elements detect, by irradiation position, reflected waves of the electromagnetic waves irradiated onto an object (ob). The memory () stores related information. The related information is information associating any two of the emission direction of the electromagnetic waves and elements defining two points on a path. The path refers to a path of the electromagnetic waves emitted from the irradiator () to the first detector () via the object (ob). The controller () updates the related information based on the emission direction of the electromagnetic waves and the position of the detection element, among the detection elements, that detects the reflected waves of the electromagnetic waves.

A display apparatus includes an image projector and a controller. The image projector emits image projection light that projects an image onto a projection-target surface. The controller controls, in a time division manner, the emission direction of the image projection light emitted by the image projector. The controller performs control to prevent the sum of the area of one or more regions of the projection-target surface, on which the image projection light is projected, from exceeding a predetermined upper limit.
