Abstract 3. Recipient’s . 023302 5. Report Date April 1971 6. Performing Organization Code 8. Performing Organization Report No, L-7441 10. Work Unit No. 125-24-04-19 11. Contract or Grant No. 13. Type of Report and Period Covered Technical Note 14. Sponsoring Agency Code The paper presents a method of determining the operating criteria necessary to operate a laser Doppler velocimeter. The basic theory used to determine the criteria is presented and programed in a computer program. The results of the program are obtained for the cross-beam technique in its three modes of operation. From the basic theory and the program, a test case was chosen to determine the best laser Doppler velocimeter to use for the test flow and the parameters required for proper operation. 17.
