    • 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. The composite sample can be based on any number of samples taken while the sensors are in any number of randomized positions.
    • 本公开通常涉及用于随机化传感器阵列中的传感器位置的系统和方法,以便减少由阵列采样的数据中的伪像,例如重影伪像。 在本公开的一个示例性实施例中,传感器阵列用于感测诸如光或声能的参数。 阵列的每个传感器在控制器的控制下是可移动的,该控制器跟踪传感器移动时的位置。 当传感器处于第一随机化模式时,至少采取一个样本。 然后将传感器随机移动到新位置,以形成新的随机化模式。 在传感器移动到新的随机模式之后,至少再抽取一个样本。 定义多个样本的数据可以组合(例如,平均)以定义复合样本。 复合样品可以基于在传感器处于任意数量的随机位置时所采集的任何数量的样品。
