Abstract

A new and flexible method to deliver target particle to sensor through optical trapping with pseudo Bessel beam is presented. Pseudo Bessel beam generator was based upon a Fourier optical system. Single mode fiber (SMF) delivered a fundamental mode without loss. SMF was spliced with Hollow optical fiber (HOF) which served as an annular aperture. A light wave with ring shape was propagated in Coreless Silica Fiber (CSF) and simultaneously transformed a Bessel shape. A Bessel shape with central peak profile will be maintained by a tiny polymer lens on the end of CSF. Delicate control of particle position was enabled by 3 pseudo Bessel beam sources which can be controlled individually. Unique characteristic of Bessel beam allows target particle to have few hundred micrometer tolerance in propagation length and sudden change of propagating direction was achieved by applying another Bessel beam source from other direction. Experimental results on Polystyrene beads which have 4 um diameter are shown. Also, living cell such as Jurkat cell was tested to check practicality.
