One moving article of System and method for for chromoscan

摘要

One surface of the Optical devices and a kind of one article of method for chromoscan that move along a travel path axis utilizes the image sensing cell including a digital color camera that can highly generate focus color image, even if when distance from a surface to video camera change when, by a tar-get be arranged in Scheimpflug configuration in optical plane in the case where video camera is provided. A branch of parallel polychromatic light of one elongate cross-section is guided in a Scheimpflug planes of scanning motion of focus and is formed towards a scanning area on the substantially homogeneous article surface of an intensity within the linear band to the depth in sensing field of a reflection of light. The linear band capture digital camera of the reflection of light is extracted with generating its two-dimentional multi-primary color image from which single line color image data. Line data is repeated when article is moved to and extracts generation successive line color image data, is built from a two-dimensional color image of which article.
