We study whether the optical properties of a solid glass retroreflector influence the value of the acceleration of gravity $g$ determined by dropping both solid and open retroreflectors in an absolute ballistic gravimeter. The retroreflectors have equivalent optical centers and are dropped from the same height, at a fixed location, in the same gravimeter while recording time data corresponding to fixed fringe separation intervals of 400 fringes. The data for both types of retroreflectors are…

Relativistic theory of the falling retroreflector gravimeter
We develop a relativistic treatment of interference between light reflected from a falling cube retroreflector in the vertical arm of an interferometer, and light in a reference beam in the

Comment on ‘Relativistic theory of the falling retroreflector gravimeter’
In the paper by Ashby (2018 Metrologia 55 1?10) the correction due to the time delay of light propagated through the prism retroreflector of absolute gravimeters is discussed. Accordingly, the
Frequency stabilization of the helium-neon laser by saturated absorption in iodine vapour
Improvements in the frequency stability of the visible helium-neon laser are possible using saturated absorption in iodine vapour. Recent improvements in the design of these lasers are discussed, and
The self-attraction correction for the FG5X absolute gravity meter
The gravitational attraction of the body of a gravity meter upon its own proof mass is sometimes called the self-attraction. The self-attraction is a source of systematic error for absolute
A new generation of absolute gravimeters
TLDR
The design improvements incorporated in a new generation of absolute gravimeters, the FG5, have led to an instrumental uncertainty estimate of 1,1 × 10-8 m s-2 (1,0 μGal).
Reply to ‘No correction for the light propagation within the cube: Comment on Relativistic theory of the falling cube gravimeter’
The comment (Nagornyi 2018 Metrologia) claims that, notwithstanding the conclusions stated in the paper Relativistic theory of the falling cube gravimeter (Ashby 2008 Metrologia 55 1–10), there is no
