LINE OPTICAL SOURCE MODULE FOR MAINTAINING FOCAL LENGTH INCLUDED X-RAY IMAGE DETECTOR USING OPTICAL SWITCHING READOUT

摘要

The present invention relates to a line light source module for an X-ray image detector using an optical switching manner, comprising a light emitting diode (LED) array having a plurality of LEDs arranged therein; an optical film for diffusing and directing light outputted from the LED array; a glass substrate for converting the light directed by the optical film to generate a line beam of a pixel size using a slit formed in one surface; and a lens array for transferring the line beam outputted from the glass substrate to an X-ray sensor included in the X-ray image detector, wherein the glass substrate is laminated between the optical film and the lens array, and the thickness of the laminated glass substrate is based on the focal distance of the lens array.
