Signal processing and data acquisition

An introduction to the basic concepts of optical phenomena and a description of routinely encountered optical components (Chapters 10 to 12). Part 3 concludes with a discussion of common photon and atomic/molecular analysis systems, and the associated detectors (Chapter 13), and a short summary of signal processing and data acquisition, as far as it is relevant to the context of this textbook (Chapter 14). 

Finally, we will conclude with a short summary of signal processing and data acquisition, as far as they are relevant in the context of this textbook (Chapter 14). 

Figure 4 shows a schematic of the detector positions in the CARPT Facility which consists of the column, the detector support structure and the signal processing and data acquisition system. The set-up consists of 16 Nal detectors (2.54 x 2.54 cm crystals) positioned around the bubble column at known locations. The column makes use of a Plexiglass plenum which can accommodate test sections of various diameters. A stainless steel porous plate distributor with an average pore size of 40 pim is sandwiched between the two sections. A positioning device was fabricated and attached to the top of the column for calibration purposes. Air to the column is supplied by a compressor and the flow rate is monitored by three parallel rotameters.
