Vg. Getmanov et al., USE OF APPROXIMATION ALGORITHMS IN COMPUTER-ASSISTED LASER VIBRATION MEASUREMENT, Measurement techniques, 40(7), 1997, pp. 657-662
This article examines the design of a computer-assisted laser vibratio
n meter that uses a special reflecting film stuck to the vibrating sur
face to eliminate the need for adjustments. Algorithms are proposed to
estimate vibrational velocity by digitally analyzing signals from the
output of a photodetector designed to detect laser radiation. An exam
ple of the use of an approximation algorithm is presented and estimate
s are made of its accuracy characteristics.
