Abstract

The application of an integrated phase plate can greatly simplify an optical system structure due to the defocus insensitivity and aberration inhibition of the wavefront coding imaging technology. In addition, the development of free-form surface technology promotes the application of integrated phase plates. In order to view the imaging characteristics of the integrated wavefront coding system, we built two kinds of wavefront coding systems with the phase plate integrated in different surfaces of the optical system. Simulation results show that phase plates with the same parameters but in different surfaces can realize consistent results. For further observation, two separated phase plates with the same parameters are processed, and, correspondingly, experiments of microscopic objective imaging are carried out. Experimental results confirm that the phase plate can be successfully applied to increase the design flexibility of wavefront coding, leading to a potential mass application solution.
