Linear array detector applications

For simple RSSF UV-visible spectroscopy, the SPD linear array is adequate for a wide variety of applications (see Section 2). The MCP-SPD linear array should extend the useful wavelength range and signal detection limits to make possible studies in the UV region between 200 and 300 nm, studies at higher scan rates and studies where the signal intensity is low. Gating on a nanosecond time scale also renders these detectors suitable for use in a variety of time-resolved spectroscopies. 

Silicon charge coupled devices (CCDs), commonly used in solid-state video cameras and in research applications, are being applied to low light level spectroscopy applications. The main advantage of area array CCDs over linear photodiode detectors is the two-dimensional format, which provides simultaneous measurements of spatial and spectral data.

The diffraction equipment used for the study of conducting polymers in no way differs fi-om that used for the study of conventional polymers. This short section does not cover the experimental methods in any technical detail, however, but merely presents some considerations about their applicability. Details can be found in the standard books on this topic [3-5]. Admittedly, these books are somewhat dated they do not, for instance, reflect the impact of computers on both automation of equipment and data evaluation. Another result of the ever-accelerating progress in microelectronics (still based on metals and inorganic semiconductors instead of polymers), is to be found in the field of x-ray detector systems linear photodiode array detectors, Charge-Coupled-Device area detectors and Image Plate detectors have all become available recently. 

For many applications a 2 cm passband may not be adequate. One may wish to see a larger number of lines of that particular gas, or one may want to search for other, possibly unknown features at the same time. One solution is to use a cryogenically cooled, low resolution grating spectrometer with a linear array of detectors at the exit of a high resolution Michelson interferometer (Fig. 5.8.12). Each detector in the array receives only radiation within a 2 cm wide interval given by the spectral resolution of the grating. With 100 detectors in the array the full... 

Since 1970 the subject of amorphous semiconductors, in particular silicon, has progressed from obscurity to product commercialization such as flat-panel liquid crystal displays, linear sensor arrays for facsimile machines, inexpensive solar panels, electrophotography, etc. Many other applications are at the developmental stage such as nuclear particle detectors, medical imaging, spatial light modulators for optical computing, and switches in neural networks (1,2).
