This disclosure provides for an impression scanner system having improved calibration having a housing and a calibration plate of known geometry. The calibration plate has a plurality of different shapes thereon. The system also has a radiation source for emitting radiation towards the shapes on the plate and a surface for reflecting images created by the radiation on the shapes. A sensor for receiving the images of the shapes as the plate moves relative to the housing is also provided. A processor compares known geometry of the plate to the images received by the sensor and calibrates the sensor based upon the known geometry and images to reduce system aberration and distortion.
