SAN JOSE, Calif., Jan. 21, 2008 -- Biomedical optics took center stage at Photonics West this weekend as the BiOS 2008 conference began. Researchers from around the globe gathered in San Jose to attend a program this week that includes the presentation of 1300 papers documenting the latest clinical and technical advances in the fast-growing field. Saturday, Jan. 19, included a presentation on a technique by Giuliano Scarcelli and Seok-Hyun Yun of Harvard Medical School that uses a Brillouin confocal microscope as a noninvasive way to monitor the density of a material as its properties change. Brillouin scattering is a...Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
    eye
    The organ of vision or light sensitivity.
    fluorescence
    Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at one wavelength and the subsequent re-emission of light at a longer wavelength. The emitted light occurs almost instantaneously and ceases when the excitation light source is removed. Key characteristics of fluorescence include: Excitation and emission wavelengths: Fluorescent materials...
    image
    In optics, an image is the reconstruction of light rays from a source or object when light from that source or object is passed through a system of optics and onto an image forming plane. Light rays passing through an optical system tend to either converge (real image) or diverge (virtual image) to a plane (also called the image plane) in which a visual reproduction of the object is formed. This reconstructed pictorial representation of the object is called an image.
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    microscope
    An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
    ophthalmology
    Ophthalmology is a branch of medicine that focuses on the anatomy, physiology, and diseases of the eyes and visual system. Ophthalmologists are medical doctors who specialize in the diagnosis, treatment, and prevention of eye disorders and diseases. They are trained to provide comprehensive eye care, including medical, surgical, and optical interventions. Key areas within ophthalmology include: General eye care: Ophthalmologists perform routine eye examinations to assess visual acuity,...
    phonon
    A phonon is a quantum of vibrational energy associated with the periodic motion of atoms or molecules in a crystalline lattice. In simpler terms, phonons are quanta of lattice vibrations in a solid material. They represent the collective vibrational modes of atoms or groups of atoms in a crystal lattice and play a crucial role in understanding the thermal and mechanical properties of materials. Key points about phonons include: Quantization of vibrational energy: Similar to photons for...
    photon
    A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
    retina
    1. The photosensitive membrane on the inside of the human eye. 2. A scanning mechanism in optical character generation.
    superresolution
    Superresolution refers to the enhancement or improvement of the spatial resolution beyond the conventional limits imposed by the diffraction of light. In the context of imaging, it is a set of techniques and algorithms that aim to achieve higher resolution images than what is traditionally possible using standard imaging systems. In conventional optical microscopy, the resolution is limited by the diffraction of light, a phenomenon described by Ernst Abbe's diffraction limit. This limit sets a...
