Alok Dhawan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Determining at least one of alignment and bond line thickness between an optical component and a mounting surface
    Patent number: 9190100
    Abstract: A bottom surface of an optical component is bonded to a mounting surface. The bottom surface includes a first opaque feature and the mounting surface includes a second opaque feature. The first and second opaque features are hidden between the bottom surface and the mounting surface after the bonding. An infrared image is obtained through a top surface of the optical component that is opposed to the bottom surface. The infrared image includes a view of a region proximate first and second opaque features. One or more of an optical alignment and a bond line thickness between the optical component and the mounting surface is determined via the infrared image.
    Type: Grant
