20060077572, Apr 13, 2006

Filed:

Oct 13, 2004

Appl. No.:

10/964468

Inventors:

Livyn Okorocha - Cincinnati OH, US
Brian Welham - Cincinnati OH, US

International Classification:

G02B 7/02

US Classification:

359819000

Abstract:

An optical system includes an optic support structure having a hollow interior with a longitudinal central axis and an optic support surface extending around the longitudinal central axis. Seats for axial and/or vertical alignment of an optic are defined on the optic support surface. The axial alignment seats can contact an outer circumferential edge of the optic, and the transverse alignment seats can contact one face of the optic. A resilient member extending transverse to the longitudinal central axis can be configured to contact the outer circumferential edge of the optic. The resilient member can apply a biasing force against the optic in a direction generally transverse to the longitudinal central axis that can force the optic against the seats of the optic support surface.

Abstract:

A cartographic means and method employs two or more compound microscopes having optical paths combined through semireflective means. One of the microscopes has means for receiving an input record in its object plane while the other has an output record in a horizontal object plane beneath its objective. Image modification means including a zoom system and preferably an image rotation mechanism and an anamorphic system are included in the input microscope system to permit the input image to be matched to the output image as both are viewed through the eyepieces. Various apparatus and methods for mounting, illuminating and scanning inputs, handling outputs, supporting the instrument, photographing the superimposed images and transferring data from input to output are described.
