摘要
A method and apparatus for detecting and recording an event is disclosed which includes a scintillator located to receive energy from the event. The energy may be x-ray energy from a radiographic source. A mirror is optionally angularly located adjacent the scintillator to redirect or reflect the light into two or more lenses. The two or more lenses have zoom capability to adjust the size of the image and the two or more lenses are arranged as telecentric lenses. A camera receives the light presented from the two or more lenses on an image plane to establish a recorded image while a shutter is presented to selectively control presentation of the light to the camera. The zoom lens allows use of different size scintillators and various CCD cameras to benefit from multiple zoom positions to best capture the image generated by the scintillator.
