MONTHLY TECHNICAL PROGRESS REPORT #5 - ATTACHMENT #1
The Preliminary Design Review was held on 22 and 23 September 1971 at
the contractor's facility. The Preliminary Design Review Briefing Package presented at
that time is included in this report as attachment #2.
A mock-up of the HILS utilizing the tungsten-halide lamp was demonstrated
in the GFE MLT-1540. It was an optically complete HILS, with motor-driven iris dim-
ming control, placed in proper relationship to the background lamps beneath one of the
viewing surfaces, allowing direct comparison between the HILS and the standard viewing
surface on the other side of the MLT. This mock-up did not include the motion or tracking
systems.
The design approach utilizing the ELH lamp, as presented and recommended
in the Briefing Package, was accepted by the customer with two points being raised:
the possibility of reducing the shadowing of the background illumination by the HILS
assembly with a slightly smaller configuration utilized in the final design; the proposed
maximum HILS motion speed of 1 "/sec. to be raised to 5"/sec. as a design goal.
A demonstration for obtaining higher light levels was presented; techniques
included removing the color correcting filter, changing the spot size, and changing the
diffuser (see attachment #2 for details). Light levels in excess of 200,000 foot lamberts
were shown.
Technical Progress for the Period Included:
Completion of Study Phase of program
Completion of the HILS mock-up assembly
Completion of temperature and cooling tests
Basic design for the final HILS assembly completed and
optical components defined
