Simultaneous multiple surface design method for diffractive surfaces.

Area of Science:

• Optical Engineering
• Diffractive Optics
• Optical Design

Background:

• Traditional optical design methods often rely on iterative optimization.
• Designing systems with multiple optical surface types can be complex.
• The simultaneous multiple surface (SMS) method offers a direct design approach.

Purpose of the Study:

• To extend the simultaneous multiple surface (SMS) design method to incorporate diffractive optical surfaces.
• To enable the direct calculation of systems containing refractive, reflective, and diffractive elements.
• To demonstrate the application of the extended SMS method in designing diffractive optical systems.

Main Methods:

• The simultaneous multiple surface (SMS) design method was adapted for diffractive surfaces.
• The method performs simultaneous and direct calculation of refractive, reflective, and diffractive surfaces.
• Phase-shift properties of diffractive elements were utilized, controlling two rays per point on each diffractive surface.

Main Results:

• The SMS method was successfully extended to design diffractive optical surfaces.
• The direct calculation approach eliminates the need for iterative optimization for these surfaces.
• Representative diffractive optical systems designed using the extended SMS method were presented.

Conclusions:

• The extended SMS method provides a powerful tool for designing complex optical systems incorporating diffractive elements.
• This approach simplifies the design process by enabling direct calculation.
• The method offers enhanced design flexibility and control through the use of diffractive surface properties.
