Approved Forease 2005/11/21: CIA-RDP78B0477S2900020025- 14 Dear John, Re: Proposed Task 11-5 "Optical Mechanical Properties of Rear Projector Light Sources" Thank you for the copy of the final report of the STAT I I"Projector Study." The report will e of considerable value if you decide to proceed with the proposed task. The data on lamp life will be directly applicable. Using the generalized approach derived in the STAT technical note "Generalized Condensing ystern we may be able to obtain a~theoretical estimate of the effect of lamp manufacturing tolerances on performance of a projection system. Since the study was principally concerned with condenser optics, we may need to modify their approach somewhat in order to study the ? effect of lamp quality. Best regards. Declass Review by NGA.
