With the advent of the linear solid-state self-scanned arrays (SSAs), a new era in spectroscopic instrumentation began. Problems relating to photographic image measurements could be circumvented by using the electronic readout afforded by the SSA. Although film readout does have some advantages, the relative advantages of SSA readout are compelling: excellent metric properties of the SSA pixels; high quantum efficiency; wide spectral range of sensitivity; electronic readout permits direct data processing of signal; high sensitivity and wide dynamic range can be achieved by using state-of-the-art electronic circuits and SSAs operated under low dark current conditions and long exposures.
