Background : ISQ calculation evaluation of in vitro laser scanning vibrometry-captured resonance frequency [3]
Laser Doppler vibrometry possesses a working principle based on the so-called Doppler effect and allows non-contact quantitative measurement of vibration (https://en.wikpedia.org/wiki/Laser_scanning_vibrometry, 2017). The Doppler effect itself finds its origin when a light beam is backscattered on a vibrating surface and experiences a change in wave phase (https://en.wikipedia.org/wiki/Doppler_effect, 2017). The backscattered laser beam is captured by the laser scanning vibrometer, and the phase change will be the function of the magnitude of the vibration of the Smartpeg. The response signal is processed and points to maximum detected resonance frequency that will be used to compute the ISQ value by means of the algorithm used by Osstell methodology. The calculated ISQ value is compared to ISQ values generated by the newest version of the Osstell device, Osstell IDx®, using a laboratory setup that enables to capture and measure, by means of laser Doppler vibrometry, the generated electromagnetic excitation of an implant-mounted Smartpeg® transducer, evoked by a the Osstell IDx device. The coefficients implemented in the formulae were confidently supplied under the agreement that publication will not be done. This computed ISQ value will be compared to the ISQ value, obtained by the Osstell IDx device in the same laboratory setup.
