ULTRA-FAST, MULTIPLE-WINDOWED SPECTROSCOPY
XCAM has developed a camera system for high frame rate multi-fibre optical spectroscopy. In this system, up to 16 user-selectable windows are defined on the CCD image and sampled, providing up to 3200 spectra per second (16 windows x 200 frames per second).
This technology was initially developed for fusion reactor diagnostics and was used to obtain the image below. The image depicts a dispersed spectrum (y-axis) of emission from a He-Ne laser as a function of time sampled at 5ms intervals (x-axis).
