Abstract

A focusing device of plenoptical type in which a plate (12) provided with apertures is inserted in the optical path between a lens (11) and, for example, an eyepiece (22). Selected parts of the light that passes through the lens is blocked by the plate. Information of the image that passes through the plate with the apertures is received by the eyepiece. The plate (12) is movable with respect to the lens to allow different optical sections to be received by the eyepiece depending on the position of the focusing plate with respect to the lens. The plate may also be rotatable with respect to the optical axis.
