Patents by Inventor Cesar A. Sciammarella

Cesar A. Sciammarella 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).

  • Patent number: 8054471
    Abstract: An optical system including a signal processing unit has been developed to study the contours of objects and/or their deformations. The optical system utilizes projectors comprising an illumination source including those outside the visible range and an observation source such as a digital camera. The optical system provides information regarding the object in such a way that renders a complete description of the surface geometry and/or its deformation. The optical system further facilitates a substantial simplification in obtaining the desired result in the form of eliminating the need for point-wise solution of simultaneous equations. The signal processing unit comprises software that, among others, provides a transformation that mimics projection and observation from infinity. The signal processing unit further reduces data processing by recognizing known geometric shapes, and automatically correcting for discontinuities of the object and/or optical system.

  • Patent number: 5671042
    Abstract: A system and process for the measurement of strains in objects using holographic interferometry comprising a continuous point light source for illuminating the object, a fringe stabilizer for compensating for the vibratory motion of the object, a detector for capturing a holographic image, a rigid body motion compensator for compensating for the rigid body motion of the object caused by displacement of the object upon application of a force, and an electronic system for reconstructing the holographic image to permit comparison of the object before and after application of a force.
