摘要
A laser thermal printing system and method utilizes a blur filter (3) made of one or more pieces of double refractive crystal material to smooth printing or laser spots or fill up gaps in an array of laser spots. Blur filter (3) is disposed between a light source (1) and a media or image plane (100). Light source (1) provides for an original array of laser spots (30) at media plane (100) and blur filter (3) splits an image of each of the original array of laser spots (30) to create a displaced duplicate array of laser spots (31) with improved spot uniformity.
