Abstract:
The system and method of sensor imager and laser alignment. The system utilizes a DLP mirror array with a compact collimator to provide a real time, direct mapping of the laser energy from a LRF onto an imager (e.g., visible, SWIR, LWIR, or the like) by using a back scatter approach. This method eliminates the thermal and vibration/shock optical alignment issues by using a relative measurement approach significantly reducing the size, weight, and cost of the alignment system.

Abstract:
Die Erfindung betrifft ein Verfahren zum Fokussieren einer Filmkamera (1), bei dem mindestens eine Hilfskamera (6, 7) zur Herstellung einer Hilfsdarstellung eines aufzunehmenden Objekts vorgesehen ist, aus der die gewünschte Fokuseinstellung bestimmt wird und ein Fokussiersignal an die Filmkamera (1) abgegeben wird. Eine verbesserte Fokussierung kann dadurch erreicht werden, dass die Hilfskamera (6, 7) lösbar mit der Filmkamera (1) verbunden ist und das Fokussiersignal an einen an der Filmkamera (1) angebrachten Servomotor ausgibt.

Abstract:
The present disclosure describes imaging techniques and devices having improved autofocus capabilities. The imaging techniques can include actively illuminating a scene and determining distances over the entire scene and so that a respective distance to each object or point in the scene can be determined. Thus, distances to all objects in a scene (within a particular range) at any given instant can be stored. A preview of the image can be displayed so as to allow a user to select a region of the scene of interest. In response to the user's selection, the imager's optical assembly can be adjusted automatically, for example, to a position that corresponds to optimal image capture of objects at the particular distance of the selected region of the scene.
Abstract:
A portable hand-holdable digital camera (10) comprises a camera housing (12) having a display (24), a power button (14), a shoot button (28), a flash unit (20), and a battery compartment; capture means (34) for capturing an image of an object in two dimensional form and for outputting the captured two-dimensional image to the display (24); first range finder means (46) including a zoomable lens unit (16) supported by the housing (12) for focusing on an object and calculation means (50) for calculating a first distance of the object from the lens unit (16) and thus a distance between points on the captured two-dimensional image viewed and selected on the display (24); and second range finder means (48) including an emitted-beam range finder (54) on the housing (12) for separately calculating a second distance of the object from the emitted-beam range finder 54, and for outputting the second distance to the calculation means (50) of the first range finder means (46) for combination therewith to improve distance determination accuracy.
Abstract:
An electronic device (100) with an image capture device (160) includes an illumination mechanism (170). The illumination mechanism (170) includes a light source with a light shaping mechanism adapted and constructed to shape light emitted from the light source into a generally 'V' shaped illumination pattern (300).
