摘要:
The invention is an imaging apparatus comprising a detector device (12) for determining points of incidence of photons and having an impact surface (13), and an aperture (16) suitable for projecting the photons to the detector device (12) having an inlet surface (17) and an outlet surface facing the impact surface (13), and comprising pinholes (18′, 18″, 22) connecting the inlet surface (17) and the outlet surface. The pinholes (18′, 18″, 22) comprise one or more central pinholes (18′, 22) and one or more peripheral pinholes (18″), and at least one central pinhole (18′, 22) and at least one peripheral pinhole (18″) are formed with focal opening (20′, 20″, 23) depth or focal opening (20′, 20″, 23) sizes different from each other. Furthermore, the invention is an aperture for the imaging apparatus and a method of manufacturing an aperture of an imaging apparatus.
