Special Issue Information

Dear colleagues,

With the development of computational and artificial intelligence technology in recent years, optical system design has changed significantly. The efficient and successful design of optical systems requires a multidisciplinary approach clearly. Advanced optical systems with high performance and compactness are extensively applied in different fields. Remarkably, freeform optics, metalens optics, and computational imaging have developed rapidly.

Therefore, in this Special Issue, “Recent Progress in Optical System Design”, we invite you to contribute your cutting-edge research in this field. Topics of interest include, but are not limited to, the following:

  1. Freeform optics design;
  2. Metalens design;
  3. Computational optical system design;
  4. Novel optical design methods;
  5. Diffractive optical system design;
  6. Novel application with optical systems.

We look forward to receiving your contributions.

Laser scanning systems are adopted for diverse applications in imaging, printing, and material processing, and there is a growing trend toward volume miniaturization without compromising optical performance. In this work, a highly compact optical configuration is proposed by combining catadioptric architecture with freeform optics. A multi-stage design method, from starting point acquisition to fine-tuning, is proposed, with particular attention to concurrently controlling physical layout and optical performance. Two systems were designed, demonstrating an average RMS wavefront error below 0.006λ and a linearity error under 0.3% over a 216 mm scanning width. The spot size deviation is below ±9%, and the position deviation is kept within half the diffraction-limited spot diameter over a ±2 mm depth of field. Compared to a conventional freeform lens design, the proposed systems reduce the total length by over 37.7%. The significant reduction in size achieved paves the way for next-generation portable and embedded laser scanning devices. Full article

As the prevalence of myopia among adolescents continues to increase, the design and fabrication of myopia control lenses have become an important research direction in modern optics. Existing myopia control lenses mostly adopt purely refractive structures, which suffer from limited design freedom, insufficient chromatic aberration suppression, and relatively large lens thickness, thereby restricting further improvement of optical performance. This paper proposes a refractive–diffractive hybrid design and fabrication method for myopia control lenses. Centered on a harmonic diffractive optical element (HDOE), an optimization model is established to balance achromatization performance and fabrication feasibility. To address the challenges of small period width, tool shadow effect, and sensitivity to machining tolerances in diffractive lenses with large-aperture and high-additional-power, harmonic design is employed to increase the period width, thereby reducing fabrication difficulty and mitigating the influence of shadowing errors on diffraction efficiency. On this basis, two lenses with different phase structures are designed: one adopts a conventional diffractive correction phase to verify the role of HDOE in achromatization and edge-thickness reduction, while the other adopts a high-degree-of-freedom smooth phase to achieve a continuous multifocal visual effect. Both lenses are fabricated by single-point diamond turning (SPDT), and the effects of surface profile and machining parameters on performance are analyzed. Simulations and measurements show that the proposed method provides stable diffraction efficiency and effective chromatic aberration correction across the design band, while reducing the edge thickness by approximately 37.85% without additional thinning of the aspheric substrate. The results indicate that the refractive–diffractive hybrid design provides a feasible design and fabrication approach for functionally more complex myopia control lenses. Full article
