Abstract:
An optical system may include an objective having at least four mirrors including an outermost mirror with aspect ratio 0.7, central obscuration 0.7 and field of view > 0.8 mm. An optical imaging system may comprise an objective and two or more imaging paths. The imaging paths may provide two or more simultaneous broadband images of a sample in two or more modes. The modes may have different illumination and/or collection pupil apertures or different pixel sizes at the sample.
Abstract:
The present invention provides an imaging module and an imaging device capable of achieving improvement of the image quality and the resolution of a plurality of simultaneously captured images having different characteristics. The present invention relates to an imaging device including a multi-lens including a central optical system (wide-angle lens) and an annular optical system (telescopic lens) which have a common optical axis, an image sensor (18), and an array lens provided on the incidence surface side of the image sensor (18) and including microlenses (pupil imaging lens). In a preferred aspect of the present invention, two images having different characteristics are generated based on a pupil image of each unit block (B) including 3×3 light reception cells assigned to each of the microlenses of the array lens. The unit block (B) has eight surrounding light reception cells that correspond to one of the two images, and the eight surrounding light reception cells in the unit block are configured to output RGB pixel signals in all wavelength regions necessary for generating this one image.
Abstract:
The present invention relates to a mobile terminal, which includes a terminal body, an optical system located in the terminal body and being configured to receive light; a rod located at a side of the optical system; and a curved mirror located at an end portion of the rod, wherein the rod and the curved mirror are positionable between a first state and a second state, wherein in the first state the rod and the curved mirror are relatively closer to the optical system, and in the second state the rod and the curved mirror have been extended outward from the optical system, and wherein the curved mirror reflects omnidirectional light incident on the curved mirror toward the optical system when in the second state.
Abstract:
The present invention provides an imaging device capable of greatly reducing the assignment number of light reception cells assigned to each microlens of an array lens and increasing the number of pixels of images having different characteristics that are captured simultaneously. One aspect of the present invention is an imaging device that includes an imaging optical system including a center optical system (wide-angle lens) and an annular optical system (telescopic lens) that share an optical axis, an image sensor (18), and an array lens (16) arranged on the incidence side of the image sensor (18) and including microlenses (pupil imaging lenses) (16a). The array lens (16) causes annular pupil images (17b) corresponding to the annular optical system adjacent to each other among a center pupil image (17a) and annular pupil images (17b) formed on the image sensor (18) by the respective microlenses (16a) to partially overlap each other on the image sensor (17).
Abstract:
Die Erfindung betrifft eine optische Aufnahmeeinrichtung (1) zur Erfassung und Verarbeitung von optischer Strahlung mit einem monolithisch ausgebildeten und mit einer homozentrischen Linsengruppe (5) ausgestatteten Objektiv (3), einer Sensoreinheit (4) mit einer planen Sensorfläche (16) und einem zwischen einer nicht planen Brennfläche (14) einer Endlinse des Objektivs (3) und der Sensorfläche (16) spaltfrei angeordneten Faserplatte (15). Um eine derartige Aufnahmeeinrichtung (1) mit geringeren Fertigungstoleranzen versehen zu können und insbesondere durch die Aufnahmeeinrichtung (1) selbst bedingtes Streulicht vermindern zu können, ist in dem Strahlengang (17) des Objektivs (3) zwischen zwei Linsen (8, 9) der homozentrischen Linsengruppe (5) ein Korrekturglied (18) eingebracht.
Abstract:
Described are new magnifying apparatus based on two dimensional arrays of micro magnifying modules (MMMs) positioned along a plane perpendicular to the center axis of the magnifying apparatus. In addition, the structure may include a two dimensional array of micro beam multipliers (MBMs) to improve the quality of the magnified image. The micro beam multipliers are positioned along a plane parallel to the array of micro magnifying modules. The structure also may include a two dimensional array of ray angle adjusters (RAAs) to extend the view angle. The ray angle adjusters are positioned along a plane parallel to the array of micro magnifying modules. The array of micro magnifying modules, with or without the micro beam multipliers and/or ray angle adjusters, may be constructed as a thin plate with a thickness of a few millimeters, through which the object is viewed. An object at a distance appears in the magnifying apparatus as a magnified image and the magnifying apparatus can be used for viewing an object at a distance in a way similar to the use of a conventional magnifier for viewing an object in a short distance.
