With the rapid development of high-speed communication and artificial intelligence
technologies, human perception of real-world scenes is no longer limited to the use of small …

In this work, a universal algorithm for designing a panoramic annular lens (PAL) system free
from stray light is proposed. The impact of a given stray light path to the optical system could …

In this work, a high-performance panoramic annular lens system designed with a point-by-
point method and variable parameter optimization strategies is proposed. Due to the …

As the visual perception window of the drone system, the lens provides great help for
obtaining visual information, detection, and recognition. However, traditional lenses carried …

Visual localization is an attractive problem that estimates the camera localization from
database images based on the query image. It is a crucial task for various applications, such …

We propose a compact form of the triple-channel panoramic annular lens (PAL) with a
stereo field and no central blind area based on polarization technology, which solves the …

We propose an ultra-wide angle panoramic imaging system based on a multiplexed
reflective surface, which consists of a panoramic head unit (PHU) and the relay lens group …

We propose a compact dual-channel panoramic annular lens (PAL) with a large aperture
and high resolution to solve three major shortcomings of conventional PAL systems …

We propose a compact catadioptric imaging system based on even aspheric elements to
solve some major limitations of conventional panoramic structure, such as field of view, blind …

We propose a new panossramic optical system that provides an additional field of view
(FOV) channel without expanding the physical size of a conventional panoramic annular …
