Abstract
A trajectory detection device includes a lens configured to receive an image of a field of view. An array of microlenses is configured to create an array of light field images based on the image. A detector array includes a plurality of photon sensitive photodetectors. The detector array is configured to generate output signals from each photodetector based on the array of light field images. A controller is configured to integrate the output signals over an integration period. At least a portion of the output signals are modulated at a modulating frequency having a modulating frequency cycle time that is smaller than the integration period. A three-dimensional image of motion in the field of view is generated based on the integration of the modulated output signals.
