Abstract:
The invention relates to an optical arrangement, particularly for the use as a main beam splitter and/or beam combiner in a microscope, wherein one or several light rays (11, 12, 15, L1, L2, L3) can be coupled into and one of the coupled light rays (11, 12, 15, L1, L2, L3) can be uncoupled again after passage of the optical arrangement (1, 11). The optical arrangement is characterized in regard to as much a free influenceability as possible of the uncoupled light ray, by having a controllable microstructured element (5), for example a digital micro mirror device (DMD), arranged in the coupled light rays (11, 12, 15, L1, L2, L3), making it possible for beam paths within the optical arrangement (1, 1') to be controllable. Thus the uncoupled light ray/s is/are controllable and/or can be influenced.
Abstract:
A smartphone endoscope system includes a smartphone with first and second imaging sensors, and an imaging optics attachment. The imaging optics attachment includes a first and second imaging apparatus, the first imaging apparatus including a first light source, a beam splitter, an objective lens, and a fiber optic imaging bundle, wherein the fiber optic imaging bundle delivers excitation light to a target which emits a fluorescence emission and a reflectance emission both collected by the fiber optic imaging bundle and transmitted to the first imaging sensor. The second imaging apparatus includes a second light source, a DRS source fiber delivering broadband light to the target which produces a diffuse reflectance emission, a DRS detection fiber, a collimator, a slit, and a transmission grating wherein the transmission grating diffracts diffuse reflectance emission and creates diffracted light which is transmitted to a second imaging sensor.
Abstract:
Eine optische Anordnung, insbesondere zum Einsatz als Hauptstrahlteiler und/oder Strahlvereiniger in einem Mikroskop, in die ein oder mehrere Lichtstrahlen (11, 12, 15, L 1 , L 2 , L 3 ) einkoppelbar sind und aus der mindesten einer der eingekoppelten Lichtstrahlen (11, 12, 15, L 1 , L 2 , L 3 ) nach Durchlaufen der optischen Anordnung (1, 11) wieder auskoppelbar ist, ist im Hinblick auf eine möglichst freie Beeinflussbarkeit des ausgekoppelten Lichtstrahls dadurch gekennzeichnet, dass in den eingekoppelten Lichtstrahlen (11, 12, 15, L 1 , L 2 , L 3 ) ein steuerbares mikrostrukturiertes Element (5), beispielsweise ein Digital Micromirror Device (DMD), angeordne ist, mit dem Strahlengänge innerhalb der optischen Anordnung (1, 1') schaltbar sind, wodurch der/die ausgekoppelte/n Lichtstrahl/en steuerbar und/oder beeinflussbar ist/sind.
Abstract:
An optical filtering device incorporates first and second prisms, the latter prism counteracting the angular dispersion of the former prism. A spatial light modulator provides a positionally variable optical stop located to block radiation within a wavelength interval and received from a location within a scene. Unobscured radiation from that and other scene locations passes to a camera, which produces an image on a display. Opaque pixels in the stop are positioned to block unwanted light sources. The invention attenuates potentially dazzling monochromatic radiation while retaining radiation at other wavelengths for imaging purposes.
