Abstract: An optical subassembly 40 and method of manufacturing an optical subassembly are provided. One subassembly 40 includes a base 42, an optical emitter 44 attached to the base 42 and one or more spacers 54 attached to the base 42 surrounding at least a portion of the optical emitter 44. The optical subassembly 40 further includes a ferrule sleeve 56 attached to the base 42 with the optical emitter 44 and one or more spacers 54 within the ferrule sleeve 56, wherein the ferrule sleeve 56 is configured to receive an optical fiber therein. The optical subassembly 40 also includes one or more reinforcement members 60 attached to the base 42 adjacent the ferrule sleeve 56 and configured to provide support to the ferrule sleeve 56.

Abstract: An apparatus for inspecting integrity of a multi-barrier wellbore is described. The apparatus includes at least one source to generate radiation to impinge a target volume of the wellbore. The apparatus includes a source collimator having a plurality of alternating blocking channels and passing channels to direct radiation to impinge the target volume, such that the radiation directed from each passing channel forms a plurality of field of views extending radially into the target volume. The apparatus further includes at least one detector to receive backscatter rays arising from each respective field of view from the plurality of field of views and to generate an image representative of an inspected portion of the wellbore. The apparatus is useful for inspecting very small volumes in the multiple barriers of the wellbore and determine the integrity of the wellbore based on the different densities in the image of the inspected portion.
