Realization of fiber-based laser Doppler vibrometer with serrodyne frequency shifting.
We demonstrate a laser Doppler vibrometer (LDV) based on the serrodyne frequency shifting technique. A proof-of-principle system is implemented on the basis of fiber-optic components but opens the way toward an ultracompact integrated LDV system on a silicon chip. With a low laser power of 50 μW, the serrodyne LDV was able to measure submicrometer vibrations with frequencies in the audio range.
متن کاملThe Novel Image-based Tracking Laser Doppler Vibrometer
An innovative version of the Tracking Laser Doppler vibrometer based on image acquisition and processing (iTLDV) is proposed. The iTLDV is developed for tracking of arbitrary motions; the system is feed-back controlled and allows to measure vibrations of moving target by driving the moving mirrors via position signals of the target obtained from a CCD camera and an image processing algorithm. T...
متن کاملRobust laser frequency stabilization by serrodyne modulation.
We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic range of 220 MHz are achieved, which leads to a strong robustness against large disturbances up to high frequencies. We demonstrate that serrodyne frequency shifting reaches a higher correction ban...
متن کاملMeasurement of the resonance frequency of single bubbles using a laser Doppler vibrometer.
The behavior of bubbles confined in tubes and channels is important in medical and industrial applications. In these small spaces, traditional means of experimentally observing bubble dynamics are often impossible or significantly perturb the system. A laser Doppler vibrometer (LDV) requires a narrow (<1 mm diameter) line-of-sight access for the beam and illumination of the bubble does not pert...
