APPARATUS AND METHOD FOR CHARACTERIZING A REPLICA TAPE

摘要

An apparatus and method are provided for characterizing a replica tape which has been embossed, compressed or cast on a surface of a material to be measured to replicate that surface. The replica tape is secured between first and second holding components such that a compressible surface of the replica tape is secured against the first holding component. A light source transmits light through the second holding component, the replica tape and the first holding component. An image sensor measures intensity of the light respectively transmitted through at least two measurement points of the compressible surface of the replica tape. A processing unit converts the measured light intensity transmitted through the at least two measurement points into at least two data values each respectively relating to a measurement statistic of the replica tape at a corresponding one of the at least two measurement points, respectively.

1. An apparatus for characterizing a replica tape which has been embossed, compressed or cast on a surface of a material, the replica tape including a first surface and an opposing second surface replicating the surface of the material on which the replica tape was embossed, compressed or cast, the second surface of the replica tape having a plurality of measurement points extending along a first direction substantially perpendicular to a thickness of the replica tape extending in a second direction between the first and second surfaces of the replica tape, wherein the apparatus comprises:
a mobile processing device including a camera and a processing unit; and a holding component having opposing first and second surfaces in the second direction, the first surface of the holding component being configured to be arranged proximate to the camera of the mobile processing device, and the second surface of the holding component being configured to secure the first surface of the replica tape to the holding component, wherein the camera of the mobile processing device is configured to measure an intensity of light transmitted in the second direction through at least two of the plurality of measurement points of the second surface of the replica tape, respectively, and wherein the processing unit of the mobile processing device is configured to receive the measured intensity of the light transmitted through the at least two of the plurality measurement points and convert the measured light intensity at the at least two measurement points into at least two data values each respectively relating to a measurement statistic of the replica tape at a corresponding one of the at least two measurement points, respectively.
