A dynamic range expansion technique for CMOS image sensors with dual charge storage in a pixel and multiple sampling technique is presented. Each pixel contains a photodiode and a storage diode which is connected to the photodiode via a separation gate. The sensitivity of the signal charge in the storage diode can be controlled either by a separation gate which limits the charge to flow into th...

6 Conclusion 23 Acknowledgments 23 Abbreviations and Acronyms 23 Related Articles 24 References 24 Modern diode laser spectroscopy is becoming an important and a more widely used tool for detection and measurement of trace gases. The change is driven by the recent advances in diode laser technology and diode laser frequency conversion techniques, which now push the limits of emission wavelength...

vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...

introduction: several treatment options have been introduced for removal of gingival hyperplasic lesions, but using diode lasers have many advantages such as less bleeding, time saving, better shaping, improved healing and less complication for the patients. case: a 15-year-old girl with multiple fibroma-like lesions in the oral cavity, who had a medical history of tuberous sclerosis, was selec...

We present a review of the use of diode lasers in atomic physics with an extensive list of references. We discuss the relevant characteristics of diode lasers and explain how to purchase and use them. We also review the various techniques that have been used to control and narrow the spectral outputs of diode lasers. Finally we present a number of examples illustrating the use of diode lasers i...

Introduction Evaluation of the delivered dose of externally wedged photon beams by external diode dosimeters during the treatment process requires the estimation of exit surface dose correction factors in various wedge angles and field sizes. Materials and Methods A system of absorbed dose evaluation, using p-type diode dosimeters placed on the exit surface of a phantom, was characterized for e...
