Hardware
Pender Technology has developed a concept for an ultra-violet imaging spectrometer
based on a fiberoptic image slicer, dispersive spectrometer, image intensifier,
and high speed CCD camera. This concept has been implemented in a system
capable of operation over a very wide dynamic range. It is capable of
detecting single photon events or being used for measurement of very intense
sources. Current development work is being done to extend the spectral range
of the device to visible wavelengths.
Software
Customized software tools were developed and integrated into
ADAPT in support of this instrument. These tools
included a photon counting mode of operation and two types of pulse height
distribution histograms, one using a peak pixel algorithm and the other using a
blob sum algorithm. These pulse height distribution tools are very useful for
image intensifier characterization. A more special purpose tool is an image
slicer mapping utility that combines image cropping, station radiation, and
generation of a local minima data set into a customized utility used for
de-convolution of spectra to spatial-spectral bins to form a spatial-spectral
data cube.
