1. A system for inspecting a jet blade, the system comprising:
a jet blade support assembly comprising:
a sub-frame,
a gripper support rotatably coupled to the sub-frame, the gripper support being tiltable about a tilting axis, and
a jet blade gripper to hold a root of the jet blade, the jet blade gripper being formed from a material that is at least partially transmissive to light, the jet blade gripper being removably couplable to the gripper support and rotatable with respect to the gripper support about a gripper rotation axis that is perpendicular to the tilting axis;
a first illumination device to illuminate at least the root of the jet blade at least partially through the jet blade gripper;
a second illumination device to illuminate at least a portion of the jet blade, the first illumination device and the second illumination device to illuminate respective portions of the jet blade from different directions; and
an optical acquisition sub-system comprising an imaging sensor to capture images.
