Abstract
Systems and methods for imaging a target object are provided. In one example, an imaging device comprises an objective lens having symmetry around an optical axis. The objective lens is configured to disperse images of a target object in longitudinal chromatic aberrations along the optical axis. The imaging device further includes a sensor configured to obtain multiple images of the target object. Each image corresponds to a specific wavelength within a predetermined spectrum.
