The separation or sorting of cellular and colloidal particles is currently a central topics of
research. In this chapter, we give an overview of the range of optical methods for cell sorting …

We introduce a novel class of planar, quasi-homogeneous Schell-model source for
producing far fields with optical lattice average intensity patterns and derive the …

Light intensity is easily quantified by using calibrated detectors that can directly exploit the
energy flux from an incident light. Spatial intensity variations can be imaged using an array …

An array of optical vortices with fractional topological charge is generated using a phase-
only Talbot array illuminator and used to sort microparticles. Our theoretical analysis and …

The authors present a power-efficient large-scale lensless optical traps on a chip (OTOCs)
as an optofluidic element for optical sorting of microparticles. Based on the well-known …

6.1 BACKGROUND All around the world, hobbyists and collectors take great pride in the
workmanship put into miniaturizations, producing small train sets with clear windows and …

Generalised phase contrast (GPC) not only leads to more accurate phase imaging beyond
thin biological samples, but serves as an enabling framework in developing tools over a …

A novel configuration of dual-channel line optical tweezers with a'Y'shape is constructed for
sorting of particles within a microfluidic chip. When yeast cells with different size pass the …

Passive microfluidic sorting techniques based upon the interaction of particles with an
optically defined potential energy landscape have possible advantages over active sorting …

We investigate the use of liquid crystal (LC) adaptive optics elements to provide full 3
dimensional particle control in an optical tweezer. These devices are suitable for single …
