Abstract: Motion picture prints made with the dye transfer, or imbibition (IB) process have a reputation for superior image quality and permanence. The process offers unique control over the dynamic range and color gamut of the prints. This invention provides for the insertion of a digital link in the traditional path of the image between the original record and the dye transfer print. The digital link provides digital means for alerting the color information in the image thereby simplifying the chemistry of the process, and enabling the manufacture of dye prints as a theatrical release medium for images originated either electronically or on film.

Abstract: A high resolution fast imaging spectrograph is disclosed which provides 400 spatial channels and 100 spectral channels of information. A collimating mirror (10) and a focusing mirror (12) face a plane diffraction grating (14), which is positioned at an acute angle to the perpendicular to the optic axis. An elongated slot (16) is cut through approximately the center of the grating allowing the light source (18) to pass through the slot and onto the collimating mirror. A turning mirror (20), which is placed at the focus of the focusing mirror and adjacent to the slot, directs radiation to a camera mirror (22), which focuses a final image outside the instrument enclosure onto a detector (24). The light source to the instrument is provided by an optical fiber ribbon. The detector will commonly be a CCD or CID 2-D detector, permitting the simultaneous measurement of spectral distribution of a spatial profile.
