Depth perception on fundus images using a single-channel stereomicroscopy
Journal of Innovative Optical Health Sciences, 2021 Typical fundus photography produces a two-dimensional image. This makes it difficult to observe the microvascular and neural abnormalities, because the depth of the image is missing. To provide depth appreciation, we develop a single-channel stereoscopic

Developing Flipped Classroom-based Mobile Learning Media to Teach Optical Physics
Scientiae Educatia: Jurnal Pendidikan Sains, 2020 The application of flipped classrooms-based M-learning media will make learning more planned and systematic. Therefore, students will be more enthusiastic and independent in the learning process. The study aims to design a flipped classrooms-based mobile

Terahertz Metamaterials for Linear Polarization Conversion and Anomalous Refraction [PDF]
Science, 2013 Converting Polarization The conversion of a light signal from one polarization direction to another plays an important role in communication and metrology. The components that are presently used for polarization conversion, however, tend to be relatively

Superboost transitions, refraction memory and super-Lorentz charge algebra [PDF]
Journal of High Energy Physics, 2018 We derive a closed-form expression of the orbit of Minkowski spacetime under arbitrary Diff(S2) super-Lorentz transformations and supertranslations. Such vacua are labelled by the superboost, superrotation and supertranslation fields.

Broadband frequency translation through time refraction in an epsilon-near-zero material
Nature Communications, 2020 Space-time duality in paraxial optical wave propagation implies the existence of intriguing effects when light interacts with a material exhibiting two refractive indexes separated by a boundary in time.

Anomalous refraction of optical spacetime wave packets [PDF]
Nature Photonics, 2019 Refraction at the interface between two materials is fundamental to the interaction of light with photonic devices and to the propagation of light through the atmosphere at large1. Underpinning the traditional rules for the refraction of an optical field

Study on the Polarization Pattern Induced by Wavy Water Surfaces
Remote Sensing, 2023 In nature, the wavy ocean surface is a common polarizer, which can change the polarization state of incident light by refraction and reflection and form a new polarization pattern different from the atmosphere.
