Cross-correlation image analysis for real-time particle tracking
Leonardo R. Werneck, Cody Jessup, Austin Brandenberger +6
Accurately measuring the translations of objects between images is essential in many fields, including biology, medicine, chemistry, and physics. One important application is track…
Active Optical Table Tilt Stabilization
Charles W. Lewandowski, Tyler D. Knowles, Zachariah B. Etienne +1
We show that a simple modification to an optical table with pneumatic vibration isolation can be used to actively reduce the long term drift in the tilt of the table by nearly a fa…
High sensitivity accelerometry with a feedback-cooled magnetically levitated microsphere
Charles W. Lewandowski, Tyler D. Knowles, Zachariah B. Etienne +1
We show that a magnetically levitated microsphere in high vacuum can be used as an accelerometer by comparing its response to that of a commercially available geophone. This system…
Cooling the Motion of a Silica Microsphere in a Magneto-Gravitational Trap in Ultra-High Vacuum
Bradley R. Slezak, Charles W. Lewandowski, Jen-Feng Hsu +1
Levitated optomechanical systems, and particularly particles trapped in vacuum, provide unique platforms for studying the mechanical behavior of objects well-isolated from their en…
Cooling the Motion of Diamond Nanocrystals in a Magneto-Gravitational Trap in High Vacuum
Jen-Feng Hsu, Peng Ji, Charles W. Lewandowski +1
Levitated diamond nanocrystals with nitrogen-vacancy (NV) centres in high vacuum have been proposed as a unique system for experiments in fundamental quantum mechanics, including t…
