Abstract
Atomic force microscope cantilevers with integrated actuation and sensing on the chip level provide several distinct advantages over conventional cantilever instrumentation. These include clean frequency responses, the possibility of down-scaling and parallelization to cantilever arrays as well as the absence of optical interferences. However, the two major difficulties […]

Steven Moore – Arbitrary placement of AFM cantilever higher eigenmodes using structural optimization

Date & Venue

Abstract
This talk presents a novel cantilever design approach to place higher mode frequencies within a specific frequency band to alleviate instrumentation and Q control feasibility. This work is motivated by the emerging field of multifrequency atomic force microscopy which involves the excitation and/or detection of several cantilever modes […]

Petter Ersbo – Displacement Estimation for Interferometry by Particle Filtering

Abstract
The current, least square (LS) based, method for displacement estimation was introduced 40 years ago. Today, computational power is much more readily available, which has opened up for the possibly employ novel and more advanced methods such as particle filtering. These methods may offer estimates with better statistical […]
