Abstract
An optical image reconstructing apparatus includes an optical image forming system. A focused surface controller moves the position of an object surface focused by the optical image forming system. An image pickup converts an image of an object formed by the optical image forming system into an electrical signal and outputs the electrical signal as an image signal. An adder adds a plurality of image signals output from the image pickup while the position of the object surface is moved by the focused surface controller. A frequency filtering device performs a frequency filtering operation on an image signal outputted from the adder to produce a filtered image signal. A rotation controller rotates the object or the optical image forming system at a predetermined angular interval around one point on an optical axis of the optical image forming system. An image synthesizing device performs interpolation on a plurality of filtered image signals output from the frequency filtering device while the object or the optical image forming system is rotated at the predetermined angular interval by the rotation controller, to synthesize images in a surface direction parallel to a rotation control surface of the rotation controller, thereby preparing a reconstructed three-dimensional image.
