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...

Eikonal tomography: surface wave tomography by phase front tracking across a regional broad-band seismic array

We present a new method of surface wave tomography based on applying the Eikonal equation to observed phase travel time surfaces computed from seismic ambient noise. The source-receiver reciprocity in the ambient noise method implies that each station can be considered to be an effective source and the phase travel time between that source and all other stations is used to track the phase front...
