Seismic Instruments, 2011
We have developed an autonomous portable digital seismometer for measurements in the field, in engineering constructions, and in hard-to-reach places. The seismometer is a monoblock including an SM-6 seismic receiver and digital seismic recorder. The SM-6 seismic receiver is a highly effective device for field work on investigating a microseismic wave ...

Bulletin of the Seismological Society of America, 1948
Abstract Theory and description are given of sensitive capacity-type seismometers having small size, eddy-current damping, and an undamped period of 0.23 second. The voltage output is taken to the grid of a cathode-follower tube within the instrument and is thereafter amplified.

We present the design of a new type of instrument to measure small doppler shifts in spectral lines. Our instrument is a form of Heterodyned, Holographic Spectrometer, here optimized for high photon efficiency. It should be suitable for the measurement of solar or stellar oscillations, which is our primary goal, or in the search for stellar-planetary ...
