A microscope having a high effective numerical aperture is achieved in an apparatus in which a real, three-dimensional image is formed of an object (E) placed in an aperture (20a) at the apex of one of two facing, axially-aligned concave mirrors (20, 10). The three-dimensional image is acquired by a video camera (50) positioned in a counterpart aperture (10a) at the apex of the other mirror and the acquired image is processed by computer (101). The processing corrects the acquired image using a point spread function of the mirror system which was previously obtained by positioning a point source of light throughout the object space and measuring the pixel values recorded by the camera's array of sensing elements while the camera was positioned at different axial distances in the image plane. |
