摘要：
An apparatus for forming stereo image pairs comprises a set of perspective apertures within a perspective aperture plate, separated within a stereoscopic horizon by an inter-aperture distance. An offset aperture is disposed inside an illuminator of the apparatus. The offset aperture is positioned to form a cone of illumination that is mirror symmetrical with respect to the two perspective apertures. The perspective apertures are adjustable both in size and in their position within the aperture plate in order to position them with respect to a cone of light produced at the perspective aperture plate. The offset aperture is similarly adjustable in size and position. The arrangement ensures that light illuminating an object viewed using the apparatus has a narrow cone of direction and angle of incidence, which ameliorates negative effects that occur in stereoscopic systems with objective lens systems having large numerical apertures.
