Different view on diffraction-limited imaging optics design

Abstract

The task of imaging optics design starts with choosing a subset of imaging parameters such as the object distance, the image magnification, the image resolution, and the depth of field. It is clear that the imaging parameters are inter-related and their appropriate trade-off is the key problem of final optical design. We provide a novel analysis of the optical design considering diffractive imaging phenomena and thin lens approximation, and we derive formulas for the solution of individual parameters. We show that combinations of three independent optical design input variables determine all other optical and geometrical parameters under diffraction-limited optical imaging. We also formulate an invariant relation in the object space if the depth of field is one of the design’s target parameters.

Optical and Electromechanical Design and Implementation of an Advanced Multispectral Device to Capture Material Appearance

“…Various optical design approaches have been proposed in the literature, often involving simplifications to streamline the design process. Němcová et al introduced a novel optical design strategy that commences from the ground up [ 28 ]. This strategy aligns well with the specific requirements of BTF and SVBRDF design, making it a proper choice for lens selection and other predefined parameters within our application.…”

“…Given these clarifications, our application aligns well with the design strategy outlined in [ 28 ], which assumes that DoF, object distance, and lens focal length are provided as inputs, and the maximum attainable resolution w is determined by the following relationship: …”

Ultra-Narrowband High-Transmissivity Guided-Mode Resonance Filter Based on Dual Dielectric Film Structure and High Refractive Index Waveguide Layer

“…Based on the fundamental principle of GMR [23], [24], [54], [26], [27], the combination of subwavelength gratings and GMR effects utilizes a periodic grating structure to ensure precise phase matching between the incident light and the intrinsic mode of the waveguide. This coupling mechanism enables the incident light that satisfies the phase match to be effectively coupled into the waveguide layer, surpassing the diffraction limit through the phenomenon of anomalous resonance [28]. As a result, a highly focused narrow-band resonance peak with remarkable transmission properties is generated.…”
