Paqe Eight Optics Lab Researchers Follow Tradition (Continued from pooge 4) puscles of the blood. The ab- sence of this particular con· stituent in the whole blood used for transfusions has provo ed lethal at high altitude in hospital planes returning from Vietnam. One of the components reo quired for the ATR unit is a polarizer for the infrared reo gion of the spectrum where at present no high performance polarizers are available. Mem· bers of the Branch have de· signed such a polarizer which shows promise of h e i n g at least one hundred times bet· ter than existing infrared pol· arizers. A test model showed very prOmISIng performance and the actual polarizer is scheduled to be built n ext month. One t e c h n i que used by members of the group is sim· ilar to that used so successful· ly by A. A. Michelson. It in· volves the interference of light waves and is extremely sensi· tive to small steps on smooth surfaces and small amounts of surface roughness. Using a special form of interferomet· er, the thickness of evaporat· ed films can be measured with an accuracy of one or two at· omic layers, about one . thou· sandth of a wavelength of light. When one realizes that a wavelength of green light is about one five . hundred . tho ousandth of an inch, the ac· curacy of the thickness mea· surement is almost unbelieva· ble. The members of the Physi- cal Optics Branch are continu- ing the tradition Michelson es- tablished for Navy scientists and are helping make Michel- son Laboratory well known in the field of precision optical measurements. Their research is disseminated to the scientif- ic community through the sev- eral pap e r s published each year in scientific journals as well as by word of mouth, and members of the group are al- ways happy to act as consult- ants for anyone who has an optical problem.

Hendershot Joins NWC Supply I Cdr. Theodore R. Hender· shot, who r e c e n tl y relieved Cdr. W. R. Guffy as Deputy Director of Supply at the Na· val Weapons Center, brings a unique background to the sup- ply functions of NWC. Prior to taking up his duties at the Center Cdr. Hendershot served with the Organization of the Joint Chiefs of Staff from June 1968 to June 1970 as Logistics Officer, Operations Team One, National Emerg- ency Airborne Command Post (NEACP), based at Andrews Air Force Base in Washington, D.C. As the Senior Logistics representative he was respon- sible for maintaining the docu- menation and presenting infor· mation concerning crisis man- agement of logistics units at the National level, and he was responsible for coordinating all logistics and damage assess- ment actions for the Command Post. Logistic problems of the "air. borne environment" of NEACP are atypical, and Cdr. Hender· shot was recently aworded the Joint Service Commendation Madal by the Joint Chiefs of Staff for "... (his) high de· gr.e of initiative and imagina. tion in solving problems unique to the airborne environment." Also the citation stated that: "he made significant and con· tinuing improvements in data bas. content and currency. Th. excellent rapport and staff lia· ison established for NEACP by Cdr. Hendershot with support· ing elements of the Organza· tion of the Joint Chiefs of Staff led to significant improvement in s u ppo rt of the Command Post minion." The medal, certificate and ci- tation were presented by Capt. M. R. Etheridge, Commander of NWC, d uri n g ceremonies held in the Commander's office and attended by Capt. E. M. Wieseke, NWC Director of Sup- ply. Cdr. Hendershot also served with the Joint Chiefs of Staff from September 1966 to June 1968 in the Office of Special Assistant for Strategic Mobil- ity. Shipboard tours he con- siders as outstanding in his Na· val career were as Supply Offi- cer on U.S.S. F. B. Parks (DD- 884), U.S.S. King (DLG·lO), and U.S.s. Topeka (CLG-8). His tour here on the Mojave Desert will contrast sharply with a pre- vious duty - Operation DEEP FREEZE II and ill-where he was Cargo Officer on the Staff of Commander, Naval Support Forces, Antarctica, a billet that was especially interesting. See And Be Seen In addition to attending the Universiti.. of Roch..ter (N. Y.) and Washington (State), he has completed courses at the Navy Postgraduate School and the Navy School of Systems and Logistics (AFln; he hos an MS dogr.. in Logistics.
