Visual optics: Focus on the Periphery

Vision is the most important sense for most people and a good optical correction, e.g. in the form of spectacles, is often taken for granted. However, it is relatively unknown how the optical errors in the peripheral visual field affect our vision. This presentation is about peripheral correction for myopia control and macular degeneration: how to measure and correct the wavefront aberrations and what effects to expect.

Vitreous floaters are one type of entoptic phenomena experienced by about 80 % of the entire population. They manifest themselves as bubbles, chains, cobwebs and other structures floating in the field of view. These are caused by cell bodies and protein structures floating in a liquified vitreous humour. Most often, they don’t point to any pathological visual condition and simply cause visual discomfort. The only effective methods how to treat them are vitreolysis and vitrectomy. While effective, both these methods are associated with serious risks to the ocular health. That’s why it is important to look for alternative solutions to this phenomenon.

Application of optical tweezers for examination of mutual interaction of red blood cells with nano-materials

The application of red blood cells (RBC) as natural transport agents for systemic drug delivery either encapsulated in the cell’s inner volume, or coupled to the surface of RBC is considered as a new paradigm in modern medicine that possesses a great potential. To reveal possible undesirable effects in routine delivery of synthetic nano-materials by RBC in day-to-day clinical practice an ultimate understanding of their mutual interaction is required. Mutual interactions of RBC incubated with various nano-materials were assessed by using optical tweezers (OT) and validated by scanning electron microscopy (SEM). The experiments are performed in a platelet-free blood plasma mimicking natural conditions. The results demonstrate that OT provides high precision measurements of RBC interaction at a pico-newton (pN) scale, whereas SEM imaging shows localization of nano-materials on the RBC membranes.

All-organic optical waveguide devices for communication and sensing applications

In the last couple of decades a tremendous growth in the use and development of waveguide photonics in the measurement technology and informatics can be noticed. This has been motivated mainly by the requirements in miniaturization of devices as well as in reduction of their costs and energy consumption. In this presentation we demonstrate our achievements in creation and characterization of all-organic waveguide devices made using direct-write optical lithography. We have used both positive and negative resists for the creation of passive elements, such as bends and resonators, and active devices such as electro-optic modulators. We will discuss the principles of the development of previously mentioned elements as well as strategies for device testing.

Spin Detection using Nitrogen-Vacancy Centres in Diamond

Nitrogen-vacancy (NV) centres in diamond have been used to detect spins on the surface of a diamond and even to perform nuclear magnetic resonance experiments on nanoscale samples. We will describe the technique and recent work and discuss ongoing research into possible applications.
