Improved fiber-optic interferometer for atomic force microscopy
Abstract
A high-sensitivity fiber-optic displacement sensor for atomic force microscopy is described. The sensor is based on the optical interference occurring in the micron-sized cavity formed between the cleaved end of a single-mode optical fiber and the microscope cantilever. As a result of using a diode laser light source and all-fiber construction, the sensor is compact, mechanically robust, and exhibits good low-frequency noise behavior. Peak-to-peak noise in a dc to 1 kHz bandwidth is less than 0.1 Å. Images are presented demonstrating atomic resolution of graphite and magnetic force imaging of bits written on a magnetic disk.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
