Abstract: PURPOSE:To attain miniaturization and to enable detection with high accuracy and high sensitivity, by reading the movement of a liquid surface due to the acceleration of two liquids different in specific gravity by the refraction or reflection of light projected from a floodlight projector. CONSTITUTION:The cavity 11 in a hermetically closed container 10 is filled with two kinds of liquids 12, 13 immiscible with each other and different in specific gravity and a refractive index and having high viscosity. A floodlight projector 14 for projecting luminous flux toward the boundary surface of the liquids 12, 13 and a two-dimensional displacement detector 15 receiving transmitted light from the boundary surface 16 are provided in opposed relationship so as to hold the cavity 11 therebetween.
