Iterative freeform lens design for prescribed irradiance on curved target

Opto-Electronic Advances, 2020
Current freeform illumination optical designs are mostly focused on producing prescribed irradiance distributions on planar targets. Here, we aim to design freeform optics that could generate a desired illumination on a curved target from a point source,

Deep Belief Network Modeling for Automatic Liver Segmentation

IEEE Access, 2019
The liver segmentation in CT scan images is a significant step toward the development of a quantitative biomarker for computer-aided diagnosis. In this paper, we propose an automatic feature learning algorithm based on the deep belief network (DBN) for ...

Designing for the dichotomy of immersion in location based games [PDF]

, 2015
The interaction design of mixed reality location based games typically focuses upon the digital content of the mobile screen, as this is characteristically the primary navigational tool players use to traverse the game space. This emphasis on the digital

Radiationless optical modes in metasurfaces: recent progress and applications

Light: Science & Applications
Non-radiative optical modes attracted enormous attention in optics due to strong light confinement and giant Q-factor at its spectral position. The destructive interference of multipoles leads to zero net-radiation and strong field trapping.
