Quantar Technology Mepsicron-II Series Single-Photon Imaging Detector System
ثبت نشده
چکیده
This detector combines the most desirable features of two fundamentally different types of traditional optical detectors into one system. The Mepsicron-II offers the exceptional ultralow-light sensitivity, low-noise, high signal-to-noise ratio and time-resolved capabilities of a digital, single-photon-counting photomultiplier (PMT) combined with the full X-Y positionsensitivity of a 1-D or 2-D array detector. Although simpler in practice, the system effectively operates much like a 23 mm diameter array of more than 125,000 microscopic (50 x 50 micron) single-photon-counting PMT's, each capable of detecting single photons with an extremely high signal-to-noise ratio. Spectra and images are created by digitally summing successive single-photon digital events.

Neural Imaging Using Single-Photon Avalanche Diodes
Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...
متن کاملThree-dimensional imaging laser radar with a photon-counting avalanche photodiode array and microchip laser.
We have developed a threedimensional imaging laser radar featuring 3-cm range resolution and single-photon sensitivity. This prototype direct-detection laser radar employs compact, all-solid-state technology for the laser and detector array. The source is a Nd:YAG microchip laser that is diode pumped, passively Q-switched, and frequency doubled. The detector is a gated, passively quenched, two-...
متن کاملSingle-photon counting
High-sensitivity detectors that are able to generate an electrical signal when struck by a single photon have two main applications. The first is for tasks involving very low light levels, such as fluorescence microscopy for biological imaging, free-space optical communications or laser ranging. The second is for singlephoton counters in quantum optics, which must often capture individual photo...

Objective(s): Systemic lupus erythematosus (SLE) is an autoimmune disease with a wide range of clinical manifestations. Cognitive dysfunction is one of the manifestations that could present prior to the emergence of any other neuropsychiatric involvements in SLE. Cognitive dysfunction is a subtle condition occurring with ahigh frequency. However, there is no data on the correlation of cognitive...
