Apparatus and method for intermediate image-formation of information propagating as wave motion passing through open hole and for image pick-up

An apparatus for forming and picking up an image comprising:

• a frontal plane having an opening acting as a primary image forming system by using waves of a first kind;
• an intermediate plane;
• a secondary image forming system using waves of a second kind, including at least one of lenses and mirrors;
• a two-dimensional image pick-up device;
• and
• a housing for integrating the frontal plane, the intermediate plane, the secondary image forming system, and the two-dimensional image pick-up device;
• wherein the frontal plane forms a first undistorted image of an object by waves of a first kind through the opening of the frontal plane onto a front surface of the intermediate plane;
• the intermediate plane converts the waves of the first kind forming the first undistorted image of the object to waves of a second kind emitted from a rear surface of the intermediate plane and acts as a wave converter from the waves of the first kind to the waves of the second kind, the waves of the second kind detectable by the two-dimensional image pick-up device;
• the secondary image forming system including at least one of lenses and mirrors forming a second distorted image by the waves of the second kind onto an image sensor of the two-dimensional image pick-up device;
• and
• the two-dimensional image pick-up device outputs a corrected image of the object by the two-dimensional image pick-up device, the correction being done by using information of the first undistorted image and the second distorted image for distortion calibration.
