  • Patent number: 9332901
    Abstract: The ophthalmic apparatus is aligned to an eye to be examined. The apparatus is used to examine the eye. It has two or more infrared or near infrared light sources for emitting light beams and a detector sensitive to infrared or near-infrared light with the capability of detecting the light reflected from the examinee's face. It registers the examination result of the eye examined. The ophthalmic apparatus is aligned to an eye to be examined. The light beam of one infrared or near infrared light source is directed to the face. The light beam of another infrared or near infrared light source is directed to pass the examinee. The direction of the light reflected from the examinee's face is detected and the examination result and the examined eye are registered to know whether the examined eye was the right eye or the left eye.

  • Patent number: 7136452
    Abstract: An imaging system for high energy radiation direct conversion scan imaging includes a high energy radiation source and a semiconductor high energy radiation direct conversion imaging device arranged around an object position. The imaging device includes a plurality of imaging cells, each imaging cell comprising a detector cell and a readout cell for producing imaging cell output values representative of high energy radiation incident on the detector cell. The source member and/or the imaging device were arranged to move substantially continuously relative to each other for scanning an object at the object position. The readout cells are operated to read out the imaging cell output values at time intervals which substantially correspond to an object image point traversing half the distance of a detector region or cell in the scanning direction. Such a configuration provides for pixel level resolution during the scanning operation.
