DOI: 10.1016/j.optcom.2017.04.073

Abstract: Abstract There is always a tradeoff between the resolution and the signal-to-noise ratio (SNR) in confocal microscopy. In particular, the pinhole size is very important for maintaining a balance between them. In this paper, we… read more here.

DOI: 10.1080/00223131.2017.1365658

Abstract: ABSTRACT In a case where a pinhole leak occurs in a fuel rod incidentally, it is possible that coolant enters the fuel rod through the pinhole. Since knowledge about the behavior of the fuel rod… read more here.

DOI: 10.3346/jkms.2017.32.5.850

Abstract: Multiple-pinhole (MPH) glasses are currently sold in many countries with unproven advertisements; however, their objective and subjective effects have not been investigated. Therefore, to investigate the effects of MPH glasses excluding the single-pinhole (SPH) effect,… read more here.

DOI: 10.3390/photonics10040399

Abstract: In this work, we developed and validated two novel imaging geometries of benchtop multi-pinhole X-ray fluorescence computed tomography (XFCT) systems with Geant4 Toolkit. One of the Monte Carlo (MC) models utilized a fan beam source… read more here.
