An image scanning device comprising of energy ray sensitive elements (101), lenses (103), a slit collimator (104) and a controller (105) is disclosed. Energy ray sensitive elements (101) refer to photo sensitive materials to capture visible light or thermal sensitive materials to capture infrared, which gives electrical signal corresponding to incident energy ray. The energy ray sensitive elements (101) are arranged in an array and the lenses (103) are arranged in an array and placed in front of the sensitive elements (101). The slit collimator (104) is used to select energy ray column to be acquired at a time. The controller (105) is used to control the motion of the slit collimator (104) from a start position to an end position, to stop at every column and acquire image data of an exposed energy ray sensitive column at a time, whereby the sequence of acquiring columns of images forms a two dimensional image.
