Fig. 9.16 — Oscillating optical tweezers
Power spectrum density of a microscopic particle held in an oscillating optical tweezers. It consists of a thermal background caused by Brownian motion plus a spike at fstage. The stage is moving sinusoidally with frequency fstage = 8 Hz and amplitude A = 150 nm along the x-direction.
