Paper Abstract

A document scanner using polymer waveguides with a microlens array was developed. The waveguide grooves and the microlenses were fabricated simultaneously by injection molding. The cores of the waveguides were formed by squeegeeing. The waveguides have multiple sharp bends to minify the image and also to reduce the size of the scanner. The microlens had a root-mean-square wavefront aberration of 0.06 λ(λ = 633 nm), and the waveguide had a transmission loss of less than 0.1 dB/cm at 633 nm. The optical system was designed to be telecentric so that the scanner had a depth of field greater than 6.0 mm (at 4 lp/mm).
