In the article we described the evolution of optical technology from lens-type microscopes working in far-field to SNOM (Scanning Near-Field Optical Microscopy) constructions. We considered two systems elaborated in our laboratory, namely PSTM system (Photon Scanning Tunelling Microscope) and SNOM system. In both systems we obtained subwavelength resolution. Some details about optical point probe technology in both systems are given and experimental results presented.
The aim of the paper is to shed light on the theoretical background of the inclusion of health in the standard of living studies, and the use of two of its specifi c measures — life expectancy at birth and body height. Hence, the article describes the idea of capabilities and functionings developed by Amartya Sen as a proposed solution to the limitations of the classic measurement of the standard of living.
