| In the case of Artyom Vitouchkine's and my most recent absolute gravimeter [12], a cam-based instrument that will be described later, this co-placement of the center of mass and optical center must be done even more precisely. Indeed, some laboratory devices, such as interferometers and gravimeters, have already begun to incorporate the new technology (SN: 8/8/98, p. Scintrex technologies include gravimeters, magnetometers, induced polarization, resistivity radiometrics and borehole logging as well as high-resolution cesium magnetic instruments. |
