Digital Holographic Microscopy (DHM) has become a powerful diagnostics tool for the sciences, especially biology. In addition, DHM has great potential for use in education because it is so flexible and affordable to schools and students. For many years, the cost and complexity of producing and using holograms limited their use to a narrow range of industry and science. Digital holography has removed these limitations making holography affordable and available to anyone who has a laptop computer. Affordable digital holocameras entering the market can enable teachers and students to produce and view their own holograms, reconstruct and view three dimensional images, and better understand and use holography in research. This paper describes such a system including exercises and experiments that explain how holograms are made and how they are used to record and analyze dynamic events that take place in three dimensions. MetroLaser’s “Holoscope”, is a lensless, DHM that produces holographic videos of microscopic objects distributed in a relatively large volume. Each frame in the video is a digital hologram that encodes 3D images that can be focused and viewed, plane by plane in detail. The three-dimensional images encoded in the holograms are electronically reconstructed, scanned, and viewed with sharp images coming in and out of focus on a computer monitor as we scan through the volume. By providing micrometer resolution throughout a cubic centimeter volume, the system effectively freezes time at the moment each frame was recorded and enables precisely tracking the 3D movement of microscopic objects in space and time. The ability to view each hologram in real-time, shows directly how interference between an object and reference wave produces interference fringes that become the hologram. Software provided with the system enables the viewer to automatically perform all of the necessary operations from hologram recording to 3D wavefront reconstruction and plane by plane imaging. We also describe more advanced and more expensive DHMs with even higher resolution that are now also available for scientific research.

Due to its ability to manufacture a single, complex part that either (1) could not have been built with traditional manufacturing or (2) would require the assembly of several sub-components, the use of Metal Additive Manufacturing (MAM) has increased over 300% in just the last 5 years1,2. Even with the advancements in the technology of Metal Additive Manufacturing, the final as-built mechanical properties continue to possess variability that make it difficult for designers and engineers to utilize them effectively, especially on mission critical parts. The final material properties of an MAM part are process and operator-dependent and the MAM process is more complex than traditional metal manufacturing techniques. The ability to non-destructively validate the quality of an MAM part is critical as the utilization of metal these parts increases. This paper describes ongoing research that focuses on techniques that can predict if a given part meets customer requirements and is free from hidden defects, flaws, non-visible geometric fluctuations, and variations in mechanical properties that are critical to the design/analysis process and mission certification. The techniques use Laser Doppler Vibrometry to detect the frequency response spectrum for a given part then process that data with non-p-value statistical techniques (Machine Learning) to develop models that can be “trained” to detect a variety of quality issues. Machine Learning models work best when data from many samples with different unacceptable end-states are available and used to train and develop the models. These end-states could be the result of a variety of unacceptable variations in the MAM process, quality of the precursor powdered metal, quality of the millions of micro-welds that make up the MAM build process, size and number of inclusions and micro flaws in the material as well as residual stresses in the part. In this study, our goals were to (1) use a large enough number of parts to ensure the validity of the machine learning model and (2) focus on geometric defects and the effects of residual stresses. For these initial investigations, we utilized Off-The-Shelf parts to increase statistical reliability, improve our ability to train our Machine Learning Model and refine our experimental protocol while keeping costs within the budget for the research. In the second phase of this research, we will use MAM parts.
