Abstract
A unity magnification catoptric image-forming system and an illumination system on the one hand, and an object- and image-surface supporting means on the other hand, are arranged for relative movement to retain the object and image surfaces in unity magnification conjugate planes of the catoptric system while effecting a scanning-type exposure of successive portions of the image surface to successively illuminated portions of the object. Fine motion mechanisms permit accurate preliminary adjustment of the object- and image-receiving surfaces relative to each other while under visual examination with the aid of the catoptric image-forming system.
Claims8
Apparatus for photographically exposing an image-receiving surface to a light image of an object, said apparatus comprising:
- an optical system having an optical axis and conjugate planes;
- a carriage;
- separate stages on said carriage for supporting an object surface and an image-receiving surface in said conjugate planes, respectively, each of said stages including four link members pivotally interconnected at points defining a parallelogram, one link member of each parallelogram being adapted for supporting thereon such object and image receiving surfaces, respectively;
- means to rotate a second link member in each parallelogram respectively opposite said one link member thereof, rotation of said second link member causing concomitant rotation of an object surface and imagereceiving surface supported on said one link member of the respective parallelogram;
- and
- means to translate said second link member of each parallelogram and means to rotate a third link member in each parallelogram, translation of said second link member in each parallelogram causing concomitant translation of such object and image-receiving surfaces in one direction and rotation of said third link member in each parallelogram causing concomitant rotation of such object surface and image-receiving surface in a direction substantially normal to said one direction.
Apparatus for photographically exposing an image-receiving surface to a light image of an object comprising:
- an optical system having an optical axis and conjugate planes parallel to each other and to said optical axis;
- a carriage;
- separate stages on said carriage for supporting an object surface and an image-receiving surface in the positions of said conjugate planes, respectively;
- means to illuminate an area in the conjugate plane in which the object surface is to be supported;
- means mounting said optical system and carriage for arcuate pivotal movement relative to one another in a direction generally parallel to said optical axis thus relatively moving simultaneously the object surface and image-receiving surface supported on the respective stages transversely of the respective conjugate planes, while moving said object surface transversely of said illuminated area, said pivotal mounting means comprising a first member fixed on the carriage;
- a second member connected to said optical system and in fixed position relative thereto;
- and first and second flexible blades mounted in planes intersecting substantially at right angles along a line coincident with the axis of said pivotal movement, each of said blades having opposite end portions connected respectively to said first and second members.
