An optical imaging device such as a fingerprint imager or a CCD camera, has a reduced size due to the provision of multiple lenses which are associated with respective CCDs. The optical path between the lenses and the CCDs is shortened. In a fingerprint version of the device, a staircase-shaped prism is advantageously used in combination with the multiple lens and multiple CCD arrangement. An alignment means is provided to facilitate the reconstructing the image out of partial images created by separate CCDs.

[ What I claim is:] [1.] An optical imaging device comprising:a source of light for illuminating an object to be imaged so that a light beam derived from said object and carrying its image is formed,image focusing means for dividing said derived light beam into a plurality of focused sub-beams carrying subimages of said object, and for focusing each of said sub-beams on a focal plane, anda plurality of charge coupled device array image sensors corresponding to said plurality of sub-beams, each image sensor disposed in a focal plane corresponding to one of said sub-beams, for receiving and converting a corresponding subimage into an electric signal and each charge coupled device array comprising an array of m x n charge coupled devices where m and n are both greater than 1.
