TECHNICAL PROGRAM STATUS
The Optical Scanner preliminary design effort was continued this
month on an accelerated level. Functional block diagrams and schematic
diagrams have evolved, and attention has been directed toward means of
implementing each of the components.
In the particular configuration under consideration, a diffuser
will have to be inserted into the optical system. This necessary addition
is being examined to determine the resolution limitations and laser power
requirements it imposes.
The three laser lines being considered are the 6328 Angstrom (red)
helium-neon line and the 5145 Angstrom (green) and 4880 Angstrom (blue) argon
lines. Chromaticity plots show that a large range of hues are possible with
these three lines. The red and green wavelengths are located at near-optimum
points on the chromaticity locus, but the blue line is at a slightly longer
wavelength than actually needed. A blue line around 4600 to 4700 Angstroms
would be closer to ideal. The effect of the longer wavelength blue presently
available is a loss of hues in the magenta region.
The final report has been started. The first sections will be
concerned with modulation and scanning techniques, lasers, conventional
light sources, active screens, and passive screens. The last section will
be a description of the conceptual design presently being studied.
A.DNINISTRA-TIVE STATUS
The percentage of the total estimated engineering dollars for the
Contract Task Order expended to date is approximately 78 percent. The present
accelerated work load is expected to continue, with emphasis on the system
design and final report.
