Abstract:
1. An optical imaging device having a housing, wherein the housing has a bottom portion, and an opposite, top portion, comprising: a. an at least partially transparent platform having a first surface, an opposite, second surface, and a thickness, h, defined therebetween by the first surface and the second surface, and positioned over the top portion of the housing for supporting a stationary image placed on the first surface; b. a reference pattern formed at a plane substantially parallel to and at a distance, d, from the first surface of the at least partially transparent platform, wherein d is greater than zero but not greater than the thickness h of the at least partially transparent platform; c. a plate placed inside the housing, wherein the plate has a first surface that is substantially reflective and an opposite, second surface, and the plate is positioned above the bottom portion such that the first surface is facing the second surface of the at least partially transparent platform; d. a number, N, of image heads, each image head having a head portion with a dimension and positioned on the plate in relation to its neighboring image heads to satisfy the relation of: with l being a characteristic dimension of the number N of image heads, and L being a characteristic distance between two neighboring image heads; and e. a light source positioned inside the housing and adapted to direct a light beam at the first surface of the plate so that the light beam is reflected to the at least partially transparent platform, reflected off the stationary image placed on the first surface of the at least partially transparent platform and received by the number N of image heads to obtain an image of the stationary image placed on the first surface of the at least partially transparent platform.
