Optical forces can be used to manipulate biological and colloidal material in a non-contact
manner. This forms the foundation of a wealth of exciting science, particularly in the fields of …

The imaging properties of optical microscopes are often compromised by aberrations that
reduce image resolution and contrast. Adaptive optics technology has been employed in …

Optical tweezers are devices that use a single, strongly focused laser beam for the remote,
noncontact trapping and manipulation of microscopic objects. Since the first demonstration …

In any optical system, distortions to a propagating wavefront reduce the spatial coherence of
a light field, making it increasingly difficult to obtain the theoretical diffraction-limited spot …

Optical micromanipulation has engendered some major studies across all of the natural
sciences at the mesoscopic scale. Though over thirty-five years old, the field is finding new …

We use digital holographic microscopy and Mie scattering theory to simultaneously
characterize and track individual colloidal particles. Each holographic snapshot provides …

We demonstrate that a structured light intensity pattern can be produced at the output of a
multi-mode optical fiber by shaping the wavefront of the input beam with a spatial light …

During the last decade, optical tweezers have been transformed by the combined availability
of spatial light modulators and the speed of low-cost computing to drive them. Holographic …

We demonstrate both theoretically and experimentally that phase gradients in a light field
can be used to create a new category of optical traps complementary to the more familiar …

Holographic optical trapping uses forces exerted by computer-generated holograms to
organize microscopic materials into three-dimensional structures. In a complementary …
