Abstract
A laser ablation tomography system includes a specimen stage for supporting a specimen. A specimen axis is defined such that a specimen disposed generally on the axis may be imaged. A laser system is operable to produce a laser sheet in a plane intersecting the specimen axis and generally perpendicular thereto. An imaging system is operable to image the area where the laser sheet intersects the specimen axis.
Claims17
A laser ablation tomography system, comprising:
- a specimen stage for supporting a specimen having a specimen axis defined from a fore end of the specimen to an aft end of the specimen;
- a laser system operable to produce a laser sheet in an imaging plane, wherein the imaging plane intersects the specimen axis and is generally perpendicular thereto, the laser sheet operable to ablate a cross-sectional slice of the specimen at the imaging plane, thereby exposing a cross-sectional surface of the specimen at the imaging plane;
- and
- an imaging system having a viewing path, the viewing path defined from the imaging plane to the imaging system, the imaging system operable to image the cross-sectional surface of the specimen being ablated during, before and/or after the laser sheet ablates a cross-sectional slice of the specimen.

A laser ablation tomography system, comprising:
- a specimen support for supporting a specimen in a specimen area, the specimen area having a specimen axis defined therethrough, the specimen axis extending from a front to a rear of the specimen area, the specimen having a fore end and an opposing aft end, wherein the fore end of the specimen is disposed toward the front of the specimen area and the aft end of the specimen is disposed toward the rear of the specimen area along the specimen axis;
- a laser system operable to produce a laser sheet in an ablation plane, wherein the ablation plane intersects the specimen axis and is generally perpendicular thereto, the laser sheet operable to ablate a cross-sectional slice of the specimen at the ablation plane, thereby exposing a cross-sectional surface of the specimen at the ablation plane;
- and
- an imaging system facing the front of the specimen area, the imaging system having a viewing path, the viewing path defined from the imaging system towards the fore end of the specimen along the specimen axis, the viewing path being generally perpendicular to the ablation plane, the imaging system operable to image the cross-sectional surface of the specimen being sliced ablated from the fore end towards the aft end during, before and/or after the laser sheet ablates a cross-sectional slice of the specimen.
