L'invention concerne un capteur sismique à fibre optique (200) avec un corps d'épreuve (110), caractérisé en ce que le corps d'épreuve (110) comprend plusieurs coupelles (113, 114, 115, 116) distinctes réparties autour de la direction de l'axe sensible du capteur et deux pièces en forme d'étoile (120, 130) disposées de part et d'autre des coupelles (113, 114, 115, 116) et reliant mécaniquement lesdites coupelles (113, 114, 115, 116) entre elles. The invention relates to a fiber-optic seismic sensor (200) with a test body (110), characterized in that the test body (110) comprises several separate dishes (113, 114, 115, 116) that are distributed around the direction of the sensitive axis of the sensor and two star-shaped elements (120, 130) placed on either side of the dishes (113, 114, 115, 116) and mechanically linking said dishes (113, 114, 115, 116) together.
