While operating the LED, concurrent laser pumping of the phosphor layer increases the light emission of the phosphor, and provides high brightness emission, e.g. in green, yellow or amber spectral regions. Additional modules, which provide emission at other wavelengths, e.g. in the UV and near UV spectral bands, together with dichroic beam-splitters/combiners allow for an efficient, compact, high-brightness illumination system, suitable for fluorescence imaging and analysis.

    Abstract: A capsule for determining the blood content of living tissue in vivo in a patient to detect tumors. The capsule includes a light source and a light detector for directing light onto the tissue and for receiving interacted light therefrom. By analyzing the interacted light, a determination can be made of the blood content of that tissue. There are various ways of positioning the capsule so that it contacts the tissue in the desired orientation of the light source and light detector. There is also a system for determining the actual contact between the capsule and the tissue. A calibration system is also used that allows a self calibration that can be carried out easily and accurately just prior to the use of the capsule.

  • Publication number: 20150094530
    Abstract: A light source apparatus for endoscopic imaging includes a light source for emitting at least narrow band blue light and narrow band green light, to illuminate an object in a body cavity. The light source is changeable over between field sequential lighting and simultaneous lighting. The light source, upon setting of the field sequential lighting, emits the narrow band blue light and narrow band green light in a discrete manner, and upon setting of the simultaneous lighting, simultaneously emits the narrow band blue light and narrow band green light. A connector is connectable with an endoscope having a complementary color image sensor of yellow, magenta and cyan, for imaging the object. A controller sets the field sequential lighting assuming that the endoscope is connected to the light source and assuming that the light source is used for emitting the narrow band blue light and narrow band green light.

    Abstract: An exemplary apparatus for imaging at least one anatomical structure can be provided. For example, the apparatus can include an endoscopic first arrangement, a radiation source second arrangement which provides at least one electro-magnetic radiation, and a third arrangement attached to at least one portion of the endoscopic arrangement. The third arrangement can contain an optical arrangement which, upon impact by the at least one electro-magnetic radiation and based thereon, may transmit a first radiation and reflects a second radiation. The first radiation can impact at least one first portion of the anatomical structure(s), and the second radiation can impact at least one second portion of the anatomical structure(s). The first and second portions can be at least partially different from one another. Further, the first and second radiations can have characteristics which are different from one another.

    Abstract: A light source apparatus outputs light for an endoscope apparatus. A blue LED emits blue light with a peak wavelength equal to or longer than 450 nm. A wavelength cut-off filter is disposed downstream of the blue LED, for cutting off a component in the blue light having a wavelength equal to or longer than the peak wavelength. Preferably, the wavelength cut-off filter cuts off a component of a wavelength equal to or longer than a reference wavelength in a wavelength range equal to or longer than the peak wavelength. A mode changer changes over an enhancement mode and a normal mode, the enhancement mode is set for enhancing and imaging a surface blood vessel of the object by use of the wavelength cut-off filter, the normal mode is set for imaging the object by disabling a function of the wavelength cut-off filter.

  • Patent number: 8956281
    Abstract: An in vivo endoscope illuminates tissue using multiple sources. Light from a short-range source exits a tubular wall of the endoscope through a first illumination region that overlaps an imaging region, and the light returns through the imaging region after reflection by tissue, to form an image in a camera. Light from a long-range source exits the tubular wall through a second illumination region that does not overlap the imaging region. The endoscope of some embodiments includes a mirror, and light from an emitter for the short-range source is split and reaches the first illumination region from both sides of an optical axis of the camera. Illuminating the first illumination region with split fractions of light results in greater uniformity of illumination, than illuminating directly with an un-split beam. The energy generated by each source is changed depending on distance of the tissue to be imaged.
