Abstract: An acoustic analysis system includes an acoustic sensor array that receives acoustic signals from a target scene and outputs acoustic data based on the one or more acoustic signals. A processor receives a first set of acoustic data representing a first portion of the target scene and having a first field of view (FOV), generates a first acoustic image based on the first set of acoustic data, receives a second set of acoustic data representing a second portion of the target scene and having a second FOV, wherein the second FOV is different than the first FOV, generates a second acoustic image based on the second set of acoustic data, registers the first acoustic image and the second acoustic image to form an aligned first acoustic image and second acoustic image, and generate a panorama comprising the aligned first acoustic image and second acoustic image for presentation on a display.

Abstract: Systems and methods can be used for analyzing image data to determine an amount of vibration and/or misalignment in an object under analysis. In some instances, as operating equipment heats up during operation, temperature changes of various portions of the operating equipment leads to changes in dimensions of such portions, leading to misalignment. Multiple sets of data representative of the operating equipment in multiple operating conditions can be used to determine an amount of misalignment due to thermal offsets. Hot and cold temperatures of the equipment can be used to calculate thermal growth of various portions of the equipment, which can be used to determine an amount a misalignment due to thermal offsets. Additionally or alternatively, image data representing the equipment can be used to observe changes in alignment between states.

Abstract: Systems and methods directed toward acoustic analysis can include a plurality of acoustic sensor arrays, each including a plurality of acoustic sensor elements, and a processor in communication with the plurality of acoustic sensor arrays. The processor can be configured to select one or more of the plurality of acoustic sensor arrays based on one or more input parameters, and generate acoustic image data representative of an acoustic scene based on received acoustic data from the selected one or more acoustic sensor arrays. Such input parameters can include distance information and/or frequency information. Different acoustic sensor arrays can share acoustic sensor elements in common or can be entirely separate from one another. Acoustic image data can be combined with electromagnetic image data from an electromagnetic imaging tool to generate a display image.

Abstract: Systems and methods can be used for analyzing image data to determine an amount of vibration and/or misalignment in an object under analysis. Image distortion present in the image data due to vibration and/or misalignment of the object during operation can be detected automatically or manually, and can be used to determine an amount of vibration and/or misalignment present. The determined amount of vibration and/or misalignment can be used to determine alignment calibration parameters for inputting into an alignment tool to facilitate alignment of the object. Various steps in determining the image distortion and/or the alignment calibration parameters can be performed using single components or can be spread across multiple components in a system.
