IMAGE SCANNING APPARATUS AND METHOD

Image scanning apparatus comprises a plurality of imaging sensors for generating image data; a focusing system and a scanning system. The focusing system defines an optical axis and directs light received from a target on to the imaging sensors. Each imaging sensor is positioned with respect to the focusing system such that, the light directed to the imaging sensor has an optical focus level with respect to the target which is different from each other imaging sensor, and the light is received from a position on the target with respect to the optical axis which is different from the respective position for each other imaging sensor. The focusing system comprises a optical path modifier so as to generate a first light path between the optical path modifier and at least one of the plurality of imaging sensors, and a second light path between the optical path modifier and at least one of the imaging sensors, wherein the first light path is different from the second light path. The scanning system is arranged in use to cause the target to be moved relative to the optical axis such that an image of the target may be generated using the image data from the plurality of image sensors. A method of using the apparatus is also disclosed.
