- 505 A Study on Sources of Error in Laser Doppler Velocimeter : An Analysis of Interference of Diffraction Images near Focal Points
抄録
Sources of errors in laser Doppler velocimeter are studied by calculating interference image produced by diffraction images of two beams come out at their convergence region. About 4% error is caused by an omission of fringe at the summit of each beam in the both 1/4 ends of the measuring region. The other about 6% error is caused by interference fringes generate on two beams outsides of the measuring region. These errors may be incompletely removed by hi-pass filtering of the measured signal. The more complete countermeasure than the former is to raise the threshold of effective fringes
