Phase imaging below the diffraction limit
Nečesal, Daniel ; Bouchal, Zdeněk (oponent) ; Dvořák, Petr (vedoucí práce)
This Master's thesis is focus on construction of phase imaging systems capable of studying both micro- and nano-sized objects. The first chapter lays the foundation of optics and nano-photonics. Then the interference of coherent waves and its practical application will be discussed for the use of breaking the diffraction limit and extracting information out of optical systems. First experimental setup discussed will be the Mach--Zehnder type in--line digital holographic microscope. We show a way to construct this device out of cheap materials and how to design its control software. Then the experimental results created using this device are presented. In the last chapter, we focus on how a SNOM holography can be implemented, how it was built, and how automation via software was utilized to reduce operator time waste. Finally, we will present experimental results obtained from our system.
