In recent years, many new camera designs have been proposed which preserve image detail over a larger depth range than conventional cameras. These methods rely on either mechanical motion or a custom optical element placed in the pupil plane of a camera lens to create the desired point spread function (PSF). This work introduces a new Spectral Focal Sweep (SFS) camera which can be used to extend depth of field (DOF) when some information about the reflectance spectra of objects being imaged is… CONTINUE READING
