Filed:

Jun 12, 1987

Appl. No.:

7/062306

Inventors:

Edward P. Goll - Wayland NY
John F. Carson - West Henrietta NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03B 2772
G03B 2780

US Classification:

355 38

Abstract:

A photographic printer includes integral densitometry apparatus for performing scanned transmissive, large area transmissive, and reflective density measurements using a single light sensor. The densitometry apparatus includes a rotatable filter wheel supporting both scanning and large area transmissive filters used in making all of the density measurements. The scanning and large area density measuring apparatus use the same light projector as and share common optical hardware with that used to print pictorial negatives. The reflection densitometry apparatus includes a detachable holder for supporting reflective patches, and a second light source activated responsive to the introduction of the holder into the printer for illuminating the reflective patch.

Appl. No.:

9/197328

Sujatha Ramanujan - Pittsford NY
David Kessler - Rochester NY
John F. Carson - West Henrietta NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03B 2732
G03B 2754

US Classification:

355 67

Abstract:

An apparatus and method of printing two-dimensional swaths of area onto a photosensitive media uses at least one reflective liquid crystal spatial light modulator. In the apparatus and method, illumination optics receive light from a light source and image the light at a polarization beamsplitter element. The polarization beamsplitter element images one polarization state of light at the spatial light modulator to create an essentially telecentric illumination at the spatial light modulator.

Appl. No.:

6/714595

Inventors:

John F. Carson - Henrietta NY
Kimon Papadopoulos - Penfield NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03B 2762

US Classification:

355 75

Abstract:

A transparent contoured support plate for use in a printing gate is disclosed which comprises a transparent glass or plastic plate having a smoothly contoured raised central area. This contoured raised area is intended to support the central area of a flexible photographic material, the edges of which are constrained by a mount having an open aperture.
