Abstract
An advanced multi-point LDV with FFT-based multi-channel signal processing, using a 1-bit FFT approach has been developed. A semiconductor laser light sheet, a 96-channel plastic optical fiber array, 16-Si APDs and a 16-channel capacious (1 M word) memory system with 1 bit were used in order to attain 16 individual Doppler frequencies simultaneously. Several experiments were conducted in this study to test the performance of the advanced multi-point LDV. We confirmed that the advanced multi-point LDV could be a useful, compact and inexpensive optical measuring instrument for obtaining the information of a velocity field as a function of time and position.
