Abstract: 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.

Abstract: A system and a method of estimating a time of flight of a signal are provided. The method includes transmitting a plurality of signals from a plurality of transmitters such that the plurality of signals travel different paths. The method also includes receiving the plurality of signals at one or more receivers. The plurality of signals are transmitted such that the plurality of signals are received at a same time instance. The method includes estimating the time of flight of a respective signal of the plurality of signals as a function of a time of reception of the plurality of signals and a respective time instance of transmission of the respective signal of the plurality of signals. The transmissions of the plurality of signals are triggered at different time instances.
