Abstract
A multi-axis self-contained sensor system includes an outer spherical housing and an inner spherical housing. The outer spherical housing has a transparent spherical shell that surrounds a first cavity and having a first refractive index (RI). The inner spherical housing is in the first cavity and is completely surrounded by the outer spherical housing. The inner spherical housing has a first average density and includes a spherical wall that surrounds a second cavity. A sensor system is contained in the second cavity, and a suspending fluid layer is interposed between the outer spherical housing and the inner spherical housing. The suspending fluid layer is composed of a fluid having a second RI.
