Researchers have developed a new imaging spectrometer that is much lighter and smaller than state-of-the-art instruments while maintaining the same high level of performance. Because of its small size and modular design, the new instrument is poised to bring this advanced analytical technique to airborne vehicles and even planetary exploration missions. https://phys.org/news/2020-11-imaging-spectrometer-compromising.html Optics & Photonics Thu, 05 Nov 2020 13:26:09 EST news523805157 Laser-scanning microscopes can be miniaturized to image microenvironments in vivo via inclusion inside optical micromechanical system (MEMS) devices to replace the existing larger components. Multifunctional active optical devices are emerging components that support miniaturization for diffraction-limited performance with simpler optical system designs in optical devices. In a recent study, Tianbo Liu and a team of researchers in the departments of Electrical and Computer Engineering and Dermatology in the U.S. proposed a catadioptric (allowing both light reflection and refraction) microscope objective lens, featuring an integrated MEMS device to perform biaxial scanning, axial focus adjustment and control spherical aberration. https://phys.org/news/2019-07-mems-in-the-lens-architecture-laser-scanning-microscopy.html General Physics Tue, 09 Jul 2019 09:30:01 EDT news481793708 Despite their tiny brains, bees have remarkable navigation capabilities based on their vision. Now scientists have recreated a light-weight imaging system mimicking a honeybee's field of view, which could change the way we build mobile robots and small flying vehicles. https://phys.org/news/2010-08-artificial-bee-eye-insight-insects.html Engineering Fri, 06 Aug 2010 00:20:01 EDT news200226410 South Korean researchers have designed and built an inexpensive optical lens that collects light from a large area and produces a virtually distortion-free wide-angle image. Standing in contrast to commonly known "fisheye" lenses, which produce significant amounts of visual distortion, low-distortion wide-angle lenses can potentially improve image-based applications such as security-camera systems and robot navigation. The new wide-angle lens is lighter, smaller and more affordable than commercially available "rectilinear" lenses, which also produce low-distortion views. https://phys.org/news/2006-11-wide-angle-lens-pictures-distortion.html General Physics Thu, 30 Nov 2006 11:56:07 EST news84110167
