Abstract
An accelerometer includes a vacuum chamber to receive one or more pairs of laser beams and a nanoparticle. Each laser beam includes an axis and a focus having three dimensions. The nanoparticle is trapped in an oscillating state in a substantially overlapping three-dimensional foci of the one or more pairs of laser beams. A processor calculates an acceleration of the nanoparticle based on changes in position of the oscillating nanoparticle. At least one photodetector identifies spatial coordinates of the oscillating nanoparticle. The at least one photodetector includes a plurality of photodetectors that are aligned to sense interference between light from a first laser beam and light from the first laser beam that is scattered by the oscillating nanoparticle. The one or more pairs of laser beams may be collinear. The one or more pairs of laser beams may be configured to point at each other.
