Patent ID: 11915405
Assignee: APPLIED OPTIMIZATION, INC.
Field: Optics (Instruments)
Classification: CPC G  B | IPC B  G

Claim 13:
14. A system, comprising:
an additive manufacturing machine configured to selectively scan a build beam across a region of interest to thereby add material to a workpiece at a moving build point located in the region of interest; and
a first optical sensor configured to generate information related to electromagnetic radiation within a first wavelength range;
a second optical sensor configured to generate information related to electromagnetic radiation within a second wavelength range;
an optics assembly comprising a beam splitter configured to split electromagnetic radiation entering the optics assembly into a first beam and a second beam, to direct the first beam to the first optical sensor, and to direct the second beam to the second optical sensor, wherein the first beam comprises electromagnetic radiation within the first wavelength range upon reaching the first optical sensor, and wherein the second beam comprises electromagnetic radiation within the second wavelength range upon reaching the second optical sensor;
a movable reflector configured to reflect electromagnetic radiation from the region of interest to the optics assembly such that each of the first optical sensor and the second optical sensor is provided with a field of view in the region of interest; and
a controller configured to move the movable reflector to maintain a predetermined relationship between the moving build point and the field of view;
wherein the build beam travels along a build beam path from a build beam source to the build point; and
wherein neither the movable reflector nor the beam splitter is positioned within the build beam path.
