Recurrence Tracking Microscope
In order to probe nanostructures on a surface we present a microscope based on the quantum recurrence phenomena. A cloud of atoms bounces off an atomic mirror connected to a cantilever and exhibits quantum recurrences. The times at which the recurrences occur depend on the initial height of the bouncing atoms above the atomic mirror, and vary following the structures on the surface under invest...
متن کاملMicroorganism Tracking Microscope System
Continuous observation of individual motile microorganisms is difficult, since their swimming speed is fast compared with their diameters. In fact, some bacteria can swim as fast as 50 diameters/s [1]. At this speed, microorganisms can quickly go out of the range of static measurement instruments, such as the field of view of optical microscopes. This problem can be solved by tracking the micro...
متن کاملThe Integer Linear Recurrence Zero Set Under the Microscope
The zero set of a linear recurrence is {m | xm = 0}, where xm is the m-th term. For a linear recurrence over the complex numbers C it is classical that xm = P1(m) · α1 + · · ·+ Pd(m) ·αd where P1(m), . . . , Pd(m) are polynomials in m, and α1, . . . , αd are the distinct zeros of the recurrence’s characteristic polynomial. We show that if the zero set of a linear recurrence over C is infinite, ...
متن کاملA Structured Illumination Method for Microscope Stage Tracking
This paper explores a new application of structured illumination to determine the position of a microscope stage. Measuring stage position accurately is important for any experiment that spans multiple fields of view. The structured illumination pattern is provided by a design printed on the microscope slide or cover slip that modulates the image of the specimen. A novel application of frequenc...
متن کاملTracking nanoparticles in an optical microscope using caustics.
An elegant method is proposed and demonstrated for tracking the location and movement of nanoparticles in an optical microscope using the optical phenomenon of caustics. A simple and reversible adjustment to the microscope generates caustics several orders of magnitude larger than the particles. The method offers a simple and relatively inexpensive method for visualizing such phenomena as the f...
