Embodiments of the present invention include a camera having two modes: a visible light imaging mode (day-mode) and an IR imaging mode (night-mode). In the visible light imaging mode, an IR filter is in line with the lens assembly. In the IR imaging mode, the IR filter is mechanically removed, and IR light is allowed to pass to the sensor. In one embodiment, in the IR imaging mode, IR lighting is provided by an IR LEDs on the camera to illuminate the scene. In one embodiment, the various components are chosen, balanced and optimized so that images captured using visible light and images captured using non-visible light are both in focus. In one embodiment, an algorithm determines when there sufficient visible light is present and when it is not, and thus determines when to switch the camera from one mode to another.

Solar rejection system with movable sunshade

Номер: US20160016678A1
Автор: Andrew L. BULLARD
Принадлежит: Raytheon Co

A solar rejection system includes an enclosure for housing a sensor, and a movable sunshade. The housing has an opening or aperture for admitting light to the sensor, and the sunshade is moved as needed to prevent harmful solar illumination of the sensor. The sunshade may be a flat panel. The sunshade panel is mounted to a hinge that is located on one side of a large diameter bearing that allows the shade to be rotated around the aperture of the sensor to always prevent the sun from illuminating the aperture. The hinge allows the shade to be tilted to either allow the sensor to see further off axis without obscuration or to block the sun when it moves in front of the sensor. Full closure of the sunshade on its hinge allows it to also function as an aperture door, blocking the opening or aperture.

Provided are a lens and a lens assembly including a lens barrel defining a receiving space and provided with a light-through hole and the lens received in the receiving space. The lens includes an optical portion for imaging and a peripheral portion provided with through holes penetrating through the peripheral portion along an optical axis of the lens. The through holes are distributed on circumferences of different diameters, centers which are located on the optical axis. The farther the circumference is from the optical axis, the more through holes are arranged on the circumference. When light enters regions of the lens where the through holes are arranged, stray light is absorbed, effectively reducing the reflection of the stray light at the peripheral portion and improving imaging quality. The through holes do not affect assembly accuracy of the lens and reduce appearance yield of the lens or increase cost.

A case for a mobile electronic device with a screen on one face and at least one camera on an opposite face. The case comprises a main body having a back wall () and upstanding sidewalls to define a cavity for the device. The back wall () has an aperture () which is aligned with the camera in the device. A recess () is formed in the side of the back wall opposite to the side forming the cavity. The recess extending laterally to the aperture and extending only partially through the depth of the back wall. A shutter () is snap fitted into the recess () and is slidably mounted with respect to the aperture. The shutter is slidable between an open position in which the aperture is uncovered and a closed position in which the aperture is covered. The surface of the shutter () facing the cavity is configured to wipe the or each camera as the shutter moves between the open and closed positions. 1. A case for a mobile electronic device with a screen on one face and at least one camera on an opposite face;the case comprising a main body having a back wall and upstanding sidewalls to define a cavity for the device;the back wall having an aperture which, in use, is aligned with the camera in the device;a recess in the side of the back wall opposite to the side forming the cavity, the recess extending laterally to the aperture and extending only partially through the depth of the back wall;a shutter snap fit into the recess and slidably mounted with respect to the aperture, the shutter being slidable between an open position in which the aperture is uncovered and a closed position in which the aperture is covered;wherein the surface of the shutter facing the cavity is configured to wipe the or each camera as the shutter moves between the open and closed positions.2. A case according to claim 1 , wherein the shutter does not project out of the recess.3. A case according to claim 1 , wherein the recess is at least partially defined by an upstanding rim extending around the ...

The invention relates to an iris device () for optical imaging systems (), comprising an aperture arrangement () and to a medical imaging system () comprising a sensor (), in particular a camera (). Conventional iris devices () known from the art unavoidably suffer a necessary trade-off between the depth of field and the amount of light transmitted through the optical system (), i.e. in particular the amount of light incident on the sensor (). This disadvantage results from the fact that iris devices (Wo one) of the art transmit or reject light in the same way for all wavelengths (), i.e. show a spectrally flat transmission property. The disadvantages of prior art iris devices () are overcome by the present invention by providing an aperture arrangement () which comprises simultaneously at least two apertures () coaxially arranged with respect to a light-transmission direction (), each of the at least two apertures () limiting light in a different spectral band () of the at least two discrete non-overlapping spectral bands (). The inventive medical imaging system () solves the above disadvantages by further comprising at least one inventive iris device (). 11711552643. An iris device () for optical imaging systems () , the iris device () comprising an aperture arrangement () , the aperture arrangement () comprising an integrated filter system () limiting light at different degrees of limitation in at least two different wavelengths ().21264754. The iris device () according to claim 1 , wherein the filter system () comprises at least one filter () having at least one light transmitting spectral band ().31264756. The iris device () according to claim 1 , wherein the filter system () comprises at least one filter () having at least one light blocking spectral band ().41268139395a. The iris device () according to claim 3 , wherein the filter system () comprises at least one ring-shaped edge filter () which surrounds a central aperture region () and in that the central ...

Although a conventional method can eliminate a mounting position deviation when left and right camera units only are taken into consideration, a problem is posed that deviation again occurs due to poor machining precision and assembly precision at the mounting surface between a camera unit and a member when a camera unit is mounted to a stay. According to this invention, mounting surfaces for mounting left and right imaging elements to a stay are provided to directly position left and right imaging elements to the stay, whereby built-up tolerance between components is reduced and the positional mounting precision between imaging elements is improved.
