During last two decades, several photon counting detectors have been developed in our laboratory. One of the most promising detector coming from our group silicon K14 Single Photon Avalanche Diode (SPAD) is presented with its valuable features and space applications. Based on the control electronics, it can be operated in both gated and non-gated mode. Although it was designed for photon counti...

The LinoSPAD camera system is a modular, compact and versatile time-resolved camera system, combining a linear 256 high fill factor pixel CMOS SPAD (single-photon avalanche diode) sensor with an FPGA (field-programmable gate array) and USB 3.0 transceiver board. This modularization permits the separate optimization or exchange of either the sensor front-end or the processing back-end, depending...

Single-photon avalanche diodes (SPADs) provide photons' time of arrival for various applications. In recent years, attempts have been made to miniaturize SPADs in order to facilitate large-array integration and in order to reduce the dead time of the device. We investigate the benefits and drawbacks of device miniaturization by characterizing a new fast SPAD in a commercial 0.18 microm compleme...

humic acid, which has hormone- like activity , not only enhances plant growth and nutrients uptake but also improve stress tolerance. to determine the effect of humic acid on the yield and vegetative characteristics of tomato an experiment was conducted with tomato cv. `isabela` in 2008 in a plastic tunnel at the agriculture faculty, guilan university using randomized completely design with fou...

abstract in order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. treatments were a combination of three levels of drought ((100, 60 and 30 percent of field capacity (fc)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a completely randomized design wi...

field trials with spathiphyllum wallisii regel were conducted at the experimental farm of faculty of agriculture, university azad jiroft in 2012 growth seasons. the aim of this work is to study the effect of foliar application with benzyladenine (ba) at 0, 100, 200 and 400 mg.l-1 and gibberellic acid (ga3) at 0, 100 and 200 mg.l-1 on the vegetative growth constituents of spathiphyllumplants. mo...

Single photon detection is one of the most challenging goals of photonics. In recent years, the study of ultra-fast and/or low-intensity phenomena has received renewed attention from the academic and industrial communities. Intense research activity has been focused on bio-imaging applications, bio-luminescence, bio-scattering methods, and, more in general, on several applications requiring hig...

A closed system for plant production with artificial light is an innovative method of cultivation. The objective this study was to investigate the effect colour on rooting cuttings and subsequent growth chrysanthemum (Chrysanthemum × grandiflorum Ramat./Kitam.) During experiments, following conditions were maintained: photoperiod 16 h or 10 h, temperature 22 °C, relative humidity 65–70%. LED la...
