Resolution in collection-mode scanning optical microscopy

Abstract: The use of small apertures or sharpened tips as sensing elements in scanned-probe optical sensing devices has led to the development of a number of instruments that provide lateral spatial resolution much finer than that available in conventional optical imaging instruments. Such a device might generally be classified as a scanning optical microscope, or SOM. One particular mode of SOM operation involves the use of a sharpened optical fiber to collect light emanating from a surface. The lateral spatial resolut… Show more

“…Theoretical treatments of Paesler and co-workers have shown, however, that resolutions down to /3 might be achieved based on the guiding properties of a tapered glass fiber. 18 We believe this to be the mechanism of our subwavelength resolution. Recently, Xiao and Bozhevolnyi have also pointed out the importance of the contributions from the middle and far fields in reflection SNOM.…”

“…Even if the film has the same crystalline perfection as the substrate, its diffraction peak is much broader due to the finite thickness effect discussed above. (311) and (422) Fig. High Resolution X-Ray Diffraction of alloy composition and mismatch based on the measurement of separation of diffraction peaks in the high resolution diffractograms has to be handled with care.…”

“…Therefore, the aperture diameter and the taper angle cannot be reduced arbitrarily because a minimum throughput must be ensured. [7][8][9][10] Part of our interest in this study is to determine the optical parameter of the taper fiber in order to improve the spatial resolution of SPECM technique, but assuring efficient throughput. The merit of this research is to take into account all the parameters that could affect spatial resolution as well as sensitivity of the SPECM technique.…”
