Optical design mode based on fast automatic design process for freeform reflective imaging systems with modest FOV

Area of Science:

• Optical Engineering
• Computational Optics
• Freeform Optics Design

Background:

• Traditional optical design relies on iterative, time-consuming manual adjustments.
• Freeform optics offer advanced performance but pose significant design challenges.
• Current methods often require extensive designer expertise and trial-and-error.

Purpose of the Study:

• To introduce a new end-to-end fast automatic design framework for freeform reflective optics.
• To demonstrate a method that bypasses traditional iterative design processes.
• To achieve high-quality optical systems with minimal human intervention and in reduced time.

Main Methods:

• Development of an end-to-end automatic design route for freeform imaging systems.
• Utilizing a simple plane system as initial input for the design process.
• Implementing high-speed trials within the automatic design framework.

Main Results:

• Successful automatic design of freeform systems with excellent image quality in 1-2 minutes.
• Generation of multiple high-performance freeform systems through repeated trials.
• Designed systems successfully addressed constraints such as volume, beam obscuration, and mirror interference.

Conclusions:
