DOI: 10.1007/s10957-018-1215-7
Abstract: In this paper, we introduce a new type of vector topical function. It contains some other categories of topical functions as special cases and can be interpreted as weak separation functions in image space analysis.… read more here.

DOI: 10.1007/s10957-019-01609-5
Abstract: In this paper, by virtue of the image space analysis, we investigate general scalar robust optimization problems with uncertainties both in the objective and constraints. Under mild assumptions, we characterize various robust solutions for different… read more here.

DOI: 10.1364/ao.516890
Abstract: Hybrid lenses are created by combining metasurface optics with refractive optics, where refractive elements contribute optical power, while metasurfaces correct optical aberrations. We present an algorithm for optimizing metasurface nanostructures within a hybrid lens, allowing… read more here.

DOI: 10.1364/ao.58.002394
Abstract: Due to the high reflectivity of the resistor array in the target scene generator (TSG), the narcissus effect caused by the resistor array is notorious. Based on the paraxial analysis of the resistor array, the… read more here.
