Wide Dynamic Range

Wide-dynamic-range sensors

Orly Yadid-Pecht, MEMBER SPIE Ben-Gurion University of the Negev Electrical and Computer Engineering Department P.O. Box 653 Beer-Sheva 84105 Israel E-mail: [email protected] Abstract. The work done to provide image sensors (CCDs and CMOS) with a wide dynamic range is reviewed. The different classes of solutions, which consist of logarithmic sensors, ‘‘clipped’’ sensors, multimode sensors, frequ...

Wide dynamic range imaging

Interest in technologies that can help improve image sensors—in terms of cost, noise and dynamic range—is growing as quickly as the market for them. Dynamic range (DR) quantifies the ability of a sensor to image highlights and shadows. If we define the dynamic range of the sensor as 20 log(S/N), where S is the maximal signal value and N is the sensor noise, the typical image sensors will have a...

Modeling of dynamic properties of cemented clay

A new shear stiffness model, Simsoil-CC, is proposed to represent dynamic properties of cemented clay. The model predicts maximum shear modulus and variation of modulus and damping as a function of shearing strain amplitude. Model parameters are determined for different types of clay and cementation agents based on laboratory data from this study and previous studies. The model, Simsoil-CC, for...

Wide-dynamic-range promoters engineered for cyanobacteria

BACKGROUND Cyanobacteria, prokaryotic cells with oxygenic photosynthesis, are excellent bioengineering targets to convert solar energy into solar fuels. Tremendous genetic engineering approaches and tools have been and still are being developed for prokaryotes. However, the progress for cyanobacteria is far behind with a specific lack of non-native inducible promoters. RESULTS We report the d...
