Among the constantly growing technologies are a range of applications utilizing miniaturized optical lenses. From smartphones and cameras in everyday life to augmented and virtual reality glasses for the latest trends of the intact era, optical lens miniaturization enables the development of a wide range of tiny products. They emphasize the significance of ultrasmall and ultrathin lens technologies based on metamaterials and meta surfaces in this paper. They cover the state-of-the-art of research trends and explore their limits, with a focus on hyper lenses and meta lenses that can replace or be integrated with current conventional lenses.
They also discuss applications that make advantage of miniature imaging equipment. The miniaturized imaging devices are likely to be critical building blocks for next-generation imaging approaches. The miniaturization of optical lenses is becoming popular. Miniaturization of optical lenses is becoming increasingly important as technology advances. Miniaturization of lenses to sub-micrometer sizes is required for the creation of tiny electronics such as mobile phones, cameras, and augmented/virtual reality devices.
A novel sort of lens, other than traditional convex or concave lenses, is necessary in this environment for two reasons. First, typical curved lens production utilizing the usual cutting or carving procedure is difficult. Second, because the wavelength of interest is not sufficiently larger than the lens dimension, the geometrical optics that underlies light focusing on those conventional lenses fails to function in this domain, and electromagnetic wave optics should be studied instead.
For these reasons, emphasis has been placed on the usage of metamaterials and meta surfaces capable of implementing. Metamaterials are optical materials that have been purposefully produced to have unusual characteristics. Meta surfaces, on the other hand, are the two-dimensional equivalents of metamaterials that may be utilized to avoid three-dimensional nanofabrication and reduce optical losses by decreasing the optical path length.
The geometrical structure, size, and arrangement of the metamaterials’ subwavelength-scale elements determine light propagation. Thus, suitably constructed metamaterials provide unparalleled control over light characteristics such as velocity, wavefront, polarization, and phase. Naturally, metamaterials and meta surfaces have been investigated as potential substitutes for traditional lenses for light focusing.
will concentrate on two types of metamaterials-based lenses in this section. First and foremost, a hyper lens is a metamaterial-based lens. It is made up of stacked metals and dielectrics in cylindrical or spherical shapes. A hyper lens has a dispersion form that is hyperbolic, allowing access to sub diffraction features with arbitrarily high spatial frequencies and the transmission of evanescent waves containing super-resolution characteristics of an object to a far-field.
Furthermore, utilizing the most recent nanofabrication processes, hyper lenses with resolutions below the diffraction limit may be fitted to a miniaturized imaging system. Hyper lenses generally have dimensions of a few micrometers, allowing them to be readily incorporated in conventional optics or employed as ultrasmall lensing devices.
The Global Next Imaging Technology Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
United Imaging, a global leader in advanced medical imaging and radiotherapy equipment manufacture and a Leadership Circle sponsor at this year’s SNMMI, is making headlines on numerous fronts this week during the SNMMI’s annual conference in Chicago.
For some time, the market has been debating the relative value of resolution, axial field of view (FOV), and time of flight (TOF).will gladly have a talk about any single specification or the cumulative benefit of all of them with the new wide-bore u MI Panorama and its 2.9 mm NEMA resolution, 35 cm axial FOV, and 194 ps timing resolution, since the need to compromise is gone with this particular device.
The u MI Panorama was recently hyped in the media as one of four new products introduced by United Imaging this year in four distinct imaging modalities. Along with the u MI Panorama, United Imaging is demonstrating u Excel, a cutting-edge Molecular Imaging technology platform. The platform combines hardware and software advancements to improve performance, imaging capabilities, and system functionality.
Its ultra-digital platform (UDP) detector has a high-performance ASIC processor, and its AI-powered workflow simplifies processes and improves examination efficiency. With a smaller dosage, exceptional image quality may be attained, and the quality assurance module ensures that the system operates at optimal performance.
The u MI Panorama is a product family that also includes the u MI Panorama GS, a 510 k-pending device with a 148 cm axial FOV. This ultra-long axial FOV system, built on the u Excel platform, enables quick and high-resolution whole-body PET/CT imaging in a single bed position. At SNMMI, the u MI Panorama GS will also be presented.
United Imaging’s popular digital PET/CT, the u MI 550, continues to witness consistent growth in demand in both mobile and stationary configurations. The whole u MI portfolio is also AI-powered from the start, rather than being retrofitted later. This enables the seamless integration of artificial intelligence (AI) across all products, optimizing everyday operations, improving patient experience, and producing outstanding diagnostic pictures.
By automatically iso-centering patients and determining the scan range, United Imaging’s artificial intelligence (uAI) accelerates typical clinical operations. Its technologies also enable for quicker scanning.
