Popis: This paper reports continued progress in the work described in our recent paper [J. Acoust. Soc. Am. 27, 728 (1955)] developing methods for calibrating vibration pickups using the wavelength of light as the standard of length. Small amplitudes are measured using a Fizeau‐type interferometer illuminated by stroboscopic light to slow or stop the apparent motion of the fringes. Large amplitudes are measured by counting fringes with a photomultiplier.
