A quanta image sensor (QIS) is a class of single-photon imaging devices that measure light intensity using oversampled binary observations. Because of the stochastic nature of the photon arrivals, data acquired by QIS is a massive stream of random binary bits. The goal of image reconstruction is to recover the underlying image from these bits. In this paper, we present a non-iterative image rec...

The purpose of the present study is to evaluate the uncertainties of in vivo dosimetry measured with diode detectors for conformal radiation therapy techniques in order to define appropriate tolerance levels for pelvis and breast treatment in MEIH (Middle East Institute of Health). The present work is carried out on 30-472 and 30-473 diode detectors irradiated by 4 and 15MV photon beams of a me...

A synthetic single crystal diamond detector (SCDD) is commercially available and is characterized for radiation dosimetry in various radiation beams in this study. The characteristics of the commercial SCDD model 60019 (PTW) with 6- and 15-MV photon beams, and 208-MeV proton beams, were investigated and compared with the pre-characterized detectors: Semiflex (model 31010) and PinPoint (model 31...

Single photon detectors sensitive to near-infrared (NIR) wavelength light are used in an increasing number of applications, such as quantum key distribution, laser detection and ranging, and integrated circuit analysis. There are many types of NIR single photon detectors, e.g. photomultiplier tube, superconducting single photon detector and single photon avalanche diode (SPAD). However, the SPA...

This paper presents a theoretical optical data pathway model. The goal is to evaluate the physics behind photonic crystal/photon relationships and to develop a theoretical model for photonic crystal implementation into VLSI system design. This paper will begin with the exploration of the fundamentals of wave propagation in photonic crystals, development of an optical transmitting device (laser ...

Qin Wang, Fei Xu, Zi-yan Yu, Xiao-shi Qian, Xi-kui Hu, Yan-qing Lu and Hui-Tian Wang National Laboratory of Solid State Microstructures Nanjing University, Nanjing 210093, China Abstract—we propose a bidirectional acousto-optic tunable optical diode based on a periodically poled lithium niobate (PPLN) waveguide with defect. An acoustic wave propagates together with the light beam so that a coll...
