Lucien LaCoste (1908 – 1995) was a physicist and metrologist. He coinvented the modern gravimeter and invented the zero-length spring and vehicle-mounted gravimeters. He was also co-founder of LaCoste Romberg , a prominent company selling gravimetric instruments.
The modern gravimeter was developed by Lucien LaCoste and Arnold Romberg in 1936. They also invented most subsequent refinements, including the ship-mounted gravimeter, in 1965, temperature-resistant instruments for deep boreholes, and lightweight hand-carried instruments.
The instrument was a gravimeter, based on the LaCoste and Romberg D-meter, [22] that primarily consists of an adjustable mass on a sprung lever attached to the instrument's measurement electronics. [ 6 ] : 4 [ 22 ] The experiment had a total mass of 12.7 kg, a volume of 26,970 cm 3 , and utilised a maximum of 9.3 W of power.

The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
The LaCoste suspension uses a zero-length spring to provide a long period (high sensitivity). [ 22 ] [ 23 ] Some modern instruments use a "triaxial" or "Galperin" design , in which three identical motion sensors are set at the same angle to the vertical but 120 degrees apart on the horizontal.
