Abstract
According to various embodiments, an electronic device may comprise: a housing comprising an inner space; a sensor structure positioned in the housing and exposed through a part of the housing, the sensor structure comprising a substantially transparent plate comprising a first surface facing away from the inner space and a second surface facing away from the first surface; a support structure positioned in the inner space so as to face the transparent plate; at least one light-emitting element mounted on the support structure while being spaced apart from the second surface and inserted between the second surface and the support structure; a spatial light modulator (SLM) disposed between the transparent plate and the LED while being spaced apart from the light-emitting element; a light-receiving element mounted on the support structure and positioned between the second surface and the support structure while being adjacent to a side surface of the light-emitting element; and a processing circuit comprising at least one electrical path electrically connected to the SLM, the processing circuit being operatively connected to the light-receiving element and configured to generate phot…
