Imaging spectrograph

This chapter will concentrate on the very high quality detectors that are needed in scientific imagers and spectrographs, and other applications that require high sensitivity, such as acquisition and guiding, adaptive optics and interferometry. We limit our discussion to focal plane arrays - large two-dimensional arrays of pixels - as opposed to single pixel detectors (e.g., avalanche photodiodes). [Pg.126]

Instrumentally, spectral FLIM generates a spectrally resolved set of lifetimes by either introducing filters to provide spectral resolution or a spectrograph between the sample and image intensifier. The first such system was created for looking at the long lifetimes of lanthanide dyes [37]. Later, a spectral FLIM system was described for measuring from a two-dimensional (2D) area of a microscope field... [Pg.84]

My approach to this issue has been to use the molecular bands of CH, CN and now NH to study the star-to-star abundance variations of C and of N. Since these bands are strong enough to be observed at moderate resolution, I can use the multiplexing capability of the Low Resolution Imaging Spectrograph at Keck (Oke et al 1995) to build up large samples. This effort is being undertaken jointly with Michael Briley of the University of Wisconsin at Oshkosh and with Peter Stetson of the National Research Council, Victoria, Canada. [Pg.104]

A spectro-radiometer-luminometer for chemiluminescence and fluorescence quantum yield studies has been described by B. G. Roberts and H. C. Hirt 187>. To obtain emission spectra from very weak chemiluminescence reactions, a large-aperture spectrograph combined with a sensitive image-intensifier tube has been used68 this was developed from a device previously constructed by Bass and Kessler 188>. With it, it was possible to record the very weak emission of singlet oxygen dimer... [Pg.131]
