Referencing system

Abstract

A reference imaging system including a planar reference piece. The reference imaging system further includes a three-axis gantry for positioning the planar reference piece at a plurality of points in a 3D coordinate system. Additionally, the reference imaging system includes a yaw actuator for adjusting the yaw angle of the object. Furthermore, the reference imaging system includes a pitch actuator for adjusting the pitch of the object. Moreover, the reference imaging system includes a computer processing unit for controlling the 3D position, pitch and yaw of the planar reference piece.

1 . A reference imaging system, comprising:
 a reference piece;   a two-axis gantry for positioning the reference piece;   a yaw actuator for adjusting the yaw angle of an object;   a pitch actuator for adjusting the pitch of the object; and   a computer processing unit for controlling the 3D position, pitch and yaw of the reference piece.   
     
     
         2 . The system of  claim 1 , further comprising an imager for recording images and reflectance data of the object. 
     
     
         3 . The system of  claim 1 , wherein the computer processing unit records the reflectance data of the object at the plurality of points. 
     
     
         4 . The system of  claim 3 , wherein the computer processing unit compares the reflectance data of the reference piece with reflectance data of a sample to determine a corrected image of the sample. 
     
     
         5 . The system of  claim 1 , wherein the reference piece comprises any color except for black. 
     
     
         6 . The system of  claim 1 , wherein the reference piece has a dimension such that an entirety of the object is contained within the length of the reference piece.
