Abstract

Apparatus and associated methods relate to autonomous devices (20) configured to map surface topologies of airfoils (18) of gas turbine engines. The autonomous device (20) moves across the airfoil (18) while remaining coupled thereto while sensing the surface topology of the airfoil (18) using an optical gel sensor (32) via an array of airfoil contacting members (54. The optical gel sensor (32) includes an optical gel (52), having nominally planar opposite surfaces (62, 64) defining a nominal gel thickness extending over an image area. A lighting element (56) illuminates the optical gel from an end of the flexible optical gel (52). A plurality of airfoil contacting members (54) extend between the flexible optical gel (52) and the airfoil (18), thereby distorting the flexible optical gel (52) in response to changes in the surface topology of the airfoil (18). A two-dimensional imager (60) images the flexible optical gel (52) over the image area, thereby creating a two-dimensional image that is indicative of the surface topology.
