delay line for high time resolution measurement: W-type
delay line,” in Rev. Sci. Instrum. 79, 083108 (2008);
Published 15 August 2008
Abstract - We propose
and demonstrate a newly designed optical delay line (W-type
delay line) that improves the resolution of optical path
length, namely, time resolution, by an order of more than
3 in comparison to the spatial resolution of a conventionally
used translational stage. Using a conventional mechanical
translational stage having a spatial resolution of 1mm,
the performance of the W-type delay line was evaluated
by interferometric measurements with a diode laser, and
the time resolution of 16 as was confirmed.
