Abstract
A projector with a detection function according to the present disclosure includes: a projection optical system that projects image light on a projection plane; an irradiation optical system that generates an irradiation beam on the basis of light obtained from a light source, and outputs the irradiation beam, in which the irradiation beam is used for detection of a detection object on the projection plane, and the detection object is configured to be detected; an imaging device that scattered light of the irradiation beam derived from the detection object enters; and an illumination control section that performs temporal light-quantity modulation of the light obtained from the light source to cause coherence of the irradiation beam to be reduced.
