摘要:
An image display device including: a light-emitting unit that is capable of individually controlling emission amounts in each of a plurality of regions constituting a screen; a display unit that displays an image on the screen; and a control unit that sets a first region in which display is performed at a predetermined brightness and a second region in which an image is displayed at a lower brightness than the predetermined brightness in the screen, wherein the control unit sets the second region in a region excluding the first region in the screen on the basis of an influence of light leakage from the first region.
摘要:
A lens module and an assembling method thereof are provided. A lens set includes a barrel and at least one lens disposed inside the barrel. A first position-limiting member is connected to the barrel. A first hollow tube surrounds the barrel and has a first sliding path. The first position-limiting member is configured to slide along the first sliding path before the first hollow tube is fixed so that the barrel is capable of moving with respect to the first hollow tube before the first hollow tube is fixed. The first position-limiting member is limited by the first sliding path. A second hollow tube surrounds the first hollow tube and has a second sliding path. The first position-limiting member is configured to slide along the second sliding path before the first and second hollow tubes are fixed. The second sliding path is inclined to the first sliding path.
摘要:
A method and apparatus to permit digital capture of images from both transmissive and reflective media. A laser or other source of excitation radiation is coupled to a mounting surface to be in optical communication with a reading window when installed on a scanner. A rear casing is coupled to the monitoring surface to engage a housing of a scanner, the housing defining the reading window.
摘要:
A radiology device comprises an X-ray source (11) for exposing a subject (S) to the radiation of said source, means (12) for converting the X-rays into optical images so as to form primary optical images, means (20) for transforming the primary optical images into secondary optical images, and means (40) for displaying the secondary images to a user, characterized in that the means for forming the secondary optical images comprise an optical chain comprising in succession, from the output of the converter to the output of the device, an image enlargement assembly (22) exposed directly to the primary images from said conversion means (12), an assembly (23) for optical intensification of the enlarged images and a photosensitive matrix sensor (25) for making said secondary images, and in that the enlargement assembly (22) is made up solely of optical elements performing no discretization of the images.
摘要:
Methods and apparatus for directing radiation to and from a sample to be scanned. In one example, first radiation propagating along a first axis is reflected off of the first axis so as to impinge on the sample. In response to the first radiation, the sample emits second radiation, which is directed to a detector. In one aspect, the second radiation is received directly from the sample by a reflector, which reflects the second radiation such that it travels substantially through air to impinge on the detector. In another aspect, the second radiation is directed such that it travels toward the detector in a direction having a significant vector component parallel to the first axis. In yet another aspect, a detection surface of the detector is oriented essentially perpendicular to the first axis and adapted to detect at least some of the second radiation traveling in a direction non-parallel to the first axis.
摘要:
A device for reading x-rays including mechanism for transporting a plurality of x-rays to and from a x-ray reading station; the transporting mechanism including a web and mechanism for securing a plurality of x-ray films to the web; the plurality of x-ray films may be spaced one from another along the web; the device including mechanism for controlling the movement of the web to sequentially transport the x-ray films to the reading station; mechanism for sensing the web and overlying x-ray film to identify the location of each x-ray film; sensing mechanism being disposed upstream of the x-ray reading station; mechanism for activating light sources behind the x-ray film and avoiding activating light sources behind the web portions not having overlying x-ray film; light activating mechanism disposed at the x-ray reading station whereby light is passed through said x-ray film and light is not passed through the web not having overlying x-ray film.

摘要:
A video system is disclosed having a weapon-mounted video camera (12) transmitting video signals to a remotely located video display (14). The video display is mounted to the helmet (40) of a soldier (36), and includes a sight reticle (50) superimposed on the image of the target (46) so that the soldier (36) can aim the weapon (38) by moving it until the target object (46) as displayed by the video display (14) is aligned with the sight reticle (50). A low probability of transmission interception of the video signals is accomplished by using a nonvisible light carrier wavelength in free space, which wavelength is characterized by a high degree of absorption due to atmospheric water vapor.
