SYSTEMS AND METHODS FOR RANDOMIZING SENSOR POSITIONS IN SENSOR ARRAYS

摘要

The present disclosure generally pertains to systems and methods for randomizing sensor positions in sensor arrays in order to reduce artifacts, such as ghost artifacts, in the data sampled by the arrays In one exemplary embodiment of the present disclosure, a sensor array is used to sense a parameter, such as light or acoustic energy Each sensor of the array is movable under the control of a controller, which tracks the position of the sensors as they are moved At least one sample is taken while the sensors are in a first randomized pattern The sensors are then randomly moved to new positions In order to form a new randomized pattern At least one additional sample is taken after the sensors have been moved to the new randomized pattern The data defining the multiple samples can be combined (e g, averaged) to define a composite sample.
