Abstract

An example apparatus includes a well plate having an array of wells, a light encoding layer positioned under the well plate, an imaging layer to capture an image of the well plate encoded by the light encoding layer, an array of electrodes positioned on a surface of a bottom floor of the at least one well, and a controller. The light encoding layer is to encode light passing through a microscopic object in at least one well of the array of wells. The light encoding layer has a substantially flat form. The controller is to direct electrical voltage to the electrodes to generate a non-rotating, non-uniform electrical field, the electrical field being to rotate an object in the electrical field.
