To address the problem of large errors in 3D maps caused by mismatching due to white flares formed through specular reflections on smooth object surfaces during digital image acquisition, we propose applying the polarization principle to filter out the orthogonally polarized component of linearly polarized light in the reflected light, thereby reducing or eliminating the white flare area. The experimental results demonstrate that the system can effectively suppress the flare intensity on nonmetallic surfaces, which mitigates artifacts in 3D reconstruction.

Current spectral adaptation of vision systems is volatile operation that relies on cascading optical filters and electronic components, resulting in bulky architectures and high energy consumption. Inspired by the spectrally tunable vision of a migratory fish, we propose a spectral-adaptive nonvolatile-operating device based on a two-dimensional MoS channel with CuInPS (CIPS) gate, in which the ferroelectric-photosensitive synergy of CIPS routes the carriers, emulating retina's adaptive feedback. The ferroelectric polarization dynamically tunes spectral synaptic plasticity and keeps the high spectral suppression ratio up to 10 without constant gate voltage or optical filters, which enhances target spectral feature extraction and elevates image recognition accuracy in cluttered scenes from 71.

This depolarization effect imposes significant limitations on the applications of vector light fields in scattering environments. In this Letter, we propose a glare suppression-based method for achieving highly polarization-pure scattering light focusing.

Purpose: Examination of the anterior segment using retro-illumination is part of the routine clinical examination, but capturing images that can be used by the clinician remains a challenge because reflections are always present, resolution is insufficient, and the patient's glare often causes motion blur. Our aim was therefore to overcome these limitations.
Methods: We modified a slit lamp by using a far-red LED, a high-resolution camera, and by modifying the light path using polarizers and an obturator to suppress reflections while optimizing the light flux.

A star-filled sky has long been a source of awe and inspiration, and its loss adversely affects human, nonhuman, and environmental health. In one generation, this majestic nighttime overstory has been lost due to national and international overuse of light-emitting diodes lighting. This article canvasses ill health effects of excessive light at night.
