Abstract

The present accelerometer has an inertia mass and a measuring device for suring a force acting on the inertia mass. The measuring device compares the intensity of light emanating from at least one optical fiber light source, with the light intensity entering at least one receiving optical fiber, after the light has been reflected, preferably repeatedly, in a gap formed by at least two reflecting surfaces. The gap is changeable by the force acting on the inertia mass. The acceleration to be measured may vary the gap width where the gap is formed between two parallel reflecting surfaces. Where the gap is formed by two surfaces including a gap defining angle, the acceleration to be measured may vary said gap defining angle.
