1. A duplex imaging apparatus for imaging at least one side of a document, having a first side and a second side, the apparatus comprising: (a) a processor; (b) memory coupled to operate with said processor; (c) a lower imaging device having a lower optical-chamber that comprises: i. at least one lower-camera mounted inside said lower optical-chamber; ii. a lower light-source-configuration, disposed inside said enclosed lower optical-chamber, facilitated to directly illuminate said first side of the document from at least two illuminating angles; and iii. a glass-window, wherein the document is operatively disposed on the external surface of said glass-window, wherein said first side of the document is disposed adjacently to said external surface of said glass-window; and (d) an upper imaging device having an upper optical-chamber that comprises: i. at least one upper-camera mounted inside said upper optical-chamber; and ii. an upper light-source-configuration, disposed inside said enclosed upper optical-chamber, facilitated to directly illuminate said second side of the document from at least two illuminating angles, wherein each of said light source configurations includes at least one cluster of light sources, and wherein said clusters of light sources are operated in a preconfigured sequence; wherein said lower-camera is preconfigured to acquire an image frame of a portion of said first side of the document being imaged and store said acquired image frame in said memory, and wherein said image acquisition is operatively coupled with the activation of each of said light sources of said lower light-source-configuration at each of said at least two illuminating angles; wherein said upper-camera is preconfigured to acquire an image frame of a portion of the second side of the document being imaged and store said acquired image frame in said memory, and wherein said image acquisition is operatively coupled with the activation of each of said light sources of said upper light-source-configuration at each of said at least two illuminating angles; wherein a space is formed between said glass-window and said upper-camera, facilitating the insertion of at least a portion of a user's hand, for insertion and removal of the document; wherein hotspots are formed in said acquire an image frames at preconfigured locations; wherein said processor is facilitated to cutout said preconfigured image frame portions containing said hotspots, forming clean portions of said acquired image frame portions; wherein said processor is facilitated to combine said clean portions of acquired image frames of said first side of the document, to form a first output image frame of said portion of said first side of the document; and wherein said processor is facilitated to combine said clean portions of acquired image frames of said second side of the document, to form a second output image frame of said portion of said second side of the document.
