A system and a method for image acquisition suitable for use in a turbine engine are disclosed. Light received from a field of view in an object plane is projected onto an image plane through an optical modulation device and is transferred through an image conduit to a sensor array. The sensor array generates a set of sampled image signals in a sensing basis based on light received from the image conduit. Finally, the sampled image signals are transformed from the sensing basis to a representation basis and a set of estimated image signals are generated therefrom. The estimated image signals are used for reconstructing an image and/or a motion-video of a region of interest within a turbine engine.
 The present invention described herein was developed at least in part in the course of Advanced Turbine Development Program executed under Contract No. DE-FC26-05NT42644 between Siemens Energy Incorporated and United States Department of Energy. Accordingly, the United States Government may have certain rights in this invention.
