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.
Claims4
A reference imaging system, comprising:
- a reference piece;
- a two-axis gantry for positioning the reference piece at a plurality of points in a 3D coordinate system;
- 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;
- wherein the computer processing unit records the reflectance data of the object at the plurality of points;
- 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.
