1. An assembly for an aircraft propulsion system, the assembly comprising:
a propulsor including a propulsor disk, a plurality of propulsor blades, and a nose cone, the propulsor disk extending circumferentially about a rotational axis, the plurality of propulsor blades circumferentially distributed about the propulsor disk, each propulsor blade of the plurality of propulsor blades extending radially between and to a root end and a tip end, the root end disposed at the propulsor disk, the propulsor disk and the plurality of propulsor blades configured to rotate about the rotational axis, the nose cone disposed axially adjacent the propulsor disk; and
an imaging assembly including an imaging device disposed on the nose cone, wherein the nose cone is rotationally fixed relative to the rotational axis, the imaging device including a camera, the camera configured to capture image data of each propulsor blade of the plurality of propulsor blades as the plurality of propulsor blades rotate about the rotational axis.
