摘要：
Infrared array cameras have enabled the measurement and mapping of dust extinction within molecular clouds to significantly greater optical depths and at significantly higher angular resolution than previously possible. In this paper we present a map of the dust extinction in the dark cloud L978 in Cygnus derived from a large-scale multi-wavelength infrared survey. Analysis of our observations reveals significant variations in cloud structure on scales smaller than our 1'.5 resolution, thus confirming trends previously observed in IC5146 dark cloud.
