Low coherence of the illumination substantially improves the quality of holographic and quantitative phase imaging (QPI) by elimination of the coherence noise and various artefacts and by improving the lateral resolution compared to the coherent holo

Light-sheet fluorescence microscopy has emerged as a powerful platform for 3-D volumetric imaging in the life sciences. Here, we introduce an important step towards its use deep inside biological tissue. Our new technique, based on digital holography

We present a simple method using an axicon and spatial light modulator to create multiple parallel Bessel beams and precisely control their individual positions in three dimensions. This technique is tested as an alternative to classical holographic

In the area of optical micro-manipulations Bessel beams are well known for their unique properties such as non-diffracting propagation over a large area or their ability to reconstruct themselves after passing a disturbing obstacle. In this paper we

Optical interference of two or more waves with different wave vectors generates a periodic, harmonic spatial profile of the optical intensity. This well known property combined with mechanical effect of light offers an excellent route to organize and

We present how to use the transfer of the momentum from the spatially periodic interference field to submicrometer-sized particles. The interference field is obtained by interference of co-propagating nondiffracting beams and counter-propagating nond

We demonstrate the use of interference between non-diffracting Bessel beams (BB) to generate a system of optical traps. They offer sub-micron particle confinement, delivery and organization over a distance of hundreds of μm. We analyze system of two

We present the first theoretical and experimental study of dielectric sub-micron particle behaviour in an optical field generated by interference of co-propagating non-diffracting beams of different propagation constants. In such a field, there are p
