# Optomechanical reference accelerometer

 Title Optomechanical reference accelerometer Publication Type Journal Article Year of Publication 2015 Authors Gerberding, O, Cervantes, FGuzman, Melcher, J, Pratt, JR, Taylor, JM Journal Metrologia Volume 52 Issue 5 Pages 654 Date Published 2015/09/08 Abstract We present an optomechanical accelerometer with high dynamic range, high bandwidth and read-out noise levels below 8 ${\mu}$g/$\sqrt{\mathrm{Hz}}$. The straightforward assembly and low cost of our device make it a prime candidate for on-site reference calibrations and autonomous navigation. We present experimental data taken with a vacuum sealed, portable prototype and deduce the achieved bias stability and scale factor accuracy. Additionally, we present a comprehensive model of the device physics that we use to analyze the fundamental noise sources and accuracy limitations of such devices.
