Evaluation of selected detector arrays for space applications Lowrance, J. L. Abstract. The development of a high density Schottky barrier Infrared Charged Coupled Device (IRCCD) type image sensor for earth observation was initiated. A dual band pixel linear array was developed, which was capable of being butted end to end to make an Author: J. L. Lowrance. suitability of detector array systems, combined with their implementation of the gamma index, in the verification and dosimetry audit of advanced IMRT. Method The response of various commercial detector array systems (Delta4®, ArcCHECK®, and the PTW 2D-Array seven õ™ and OCTAVIUS II™ phantom combination, Gafchromic® EBT2 and composite EPID. These have been checked and updated where necessary, and it is hoped that the book will carry on being an up-to- date reference guide for users of detector array instrumentation for a considerable time to come. Solid state imaging arrays have many advantages as sensors of optical radiation compared with discrete, single-element detectors. At the Goddard Space Flight Center (GSFC) Detector Development Laboratory (DDL), we have custom designed and fabricated a chip which consists of an interleaved linear array of 1× pinned photo-diode (PD) sensing pixels, which have dimensions μm×6 μm, together with a parallel detector register and a serial readout register. The registers use a triple polysilicon CCD design.

InSb Detector Array. InSb detector arrays have found many applications in MWIR due to their spatial uniformity, low dark current and image quality. This technology has evolved over the years in response to the stringent requirements for applications in missile seekers and missile warning systems (MWS) . For these applications, the. Anders C. Onshage, in Handbook of Sensors and Actuators, Summary. The use of the Z-technology [1 -3] results in a very compact detector unit. The detector unit is made by connecting a two-dimensional detector array to an end of a module formed by a layered structure. The layered structure comprises means for reading-out information from the detector array. The main characteristics of present and future detector types for space applications discussed in this volume are summarised in the form of a table. The order follows wavelength range. Only the most important features and capabilities of the detectors in question are listed; details are found in the corresponding chapters, where the.
Rongqing Hui, in Introduction to Fiber-Optic Communications, Introduction. Photodetector is the key device in the front end of an optical receiver that converts the incoming optical signal into an electrical signal, known as O/E convertor. Semiconductor photodetectors, commonly referred to as photodiodes, are the predominant types of photodetectors used in optical communication systems. array detector (DAD) system at selected wave length sets, (A), (B), (C), (D) and (E). Three LC-chemometric approaches were applied to the multichromatographic. 03 Teledyne e2v sensors optimised for ground-based and space applications  SESSION 2 IR DETECTOR DEVELOPMENT 05 Development of astronomy large focal plane array "ALFA" at Sofradir and CEA  07 A monolithic 2k × 2k LWIR HgCdTe detector array for passively cooled space missions  SESSION 3 CCD. Additionally, an array of detectors is more robust than using a single detector if the system breaks down due to a fault in a given detector. Hence, the use of an array of smaller detectors in this regard is a much better choice than a single detector from the perspectives of probability of .
