An Introduction to Coherence Scanning Interferometry
Abstract: The story of coherence scanning interferometry (CSI) is a journey through the history of optics, beginning with the discovery of interference fringes and leading up to present-day methods of surface structure analysis. For a time, after the invention of the laser, the principles of low-coherence interferometry were forgotten, as researchers raced to develop laser-based distance sensors. The rediscovery of white light methods thirty years ago dramatically advanced applications for high precision measurements using light waves, leading to modern CSI microscopy.
In this lecture, I trace the history of interferometry with incoherent light sources from Newton’s colored bands to the current state of the art in optical metrology. We will see how the fundamentals of coherence and fringe formation enable manufacturing metrology for everything from engine parts to virtual reality headsets. Current topics include both practical instrument design as well as scattering theory applied to the interaction of light with surfaces.

Portable Structured-light Metrology System for Form Measurement of Composite Structured Surfaces
Abstract: A portable hybrid structured-light based measurement system is presented for in-situ and embedded form metrology of structured composite surfaces. The proposed technique contains three subsystems: phase measuring deflectometry (PMD) subsystem, fringe projection profilometry (FPP) subsystem, and stereo vision subsystem. PMD subsystem accurately reconstructs the form data of specular surfaces based on the principle of structured-light reflection, while FPP subsystem measures rough surfaces by projecting structured light on the measured surfaces. Then the output data from the subsystems are stitched to reconstruct a complete form of the measured composite surfaces. An embedded measurement experiment in a diamond turning machine demonstrates that the proposed techniques can achieve 24.8 µm form accuracy in rough surface measurement and 400 nm form accuracy in specular surface measurement.

On-chip Computational Hyperspectral Imaging with High Spatial and Temporal Resolution
Abstract: Hyperspectral imaging provides high-dimensional spatial-temporal-spectral information revealing intrinsic matter characteristics. Here we report an on-chip computational hyperspectral imaging framework with high spatial and temporal resolution. By integrating different broadband modulation materials on the imaging sensor chip, the target spectral information is non-uniformly and intrinsically coupled on each pixel with high light throughput. Using intelligent reconstruction algorithms, multi-channel images can be recovered from each frame, realizing real-time hyperspectral imaging. Following such a framework, we for the first time fabricated a broadband (400-1700 nm) hyperspectral imaging sensor using photolithography, with an average light throughput of 74.8% and 96 wavelength channels. The demonstrated resolution is 1024×1024 pixels at 124 fps. We demonstrated its wide applications including chlorophyll and sugar quantification for intelligent agriculture, blood oxygen and water quality monitoring for human health, textile classification and apple bruise detection for industrial automation, and remote lunar detection for astronomy. The integrated hyperspectral imaging sensor weighs only tens of grams, and can be assembled on various resource-limited platforms or equipped with off-the-shelf optical systems. The technique transforms the challenge of high-dimensional imaging from a high-cost manufacturing and cumbersome system to one that is solvable through on-chip compression and agile computation.

Engineered Microsphere and Compound Lens for Optical Nano-Imaging
Abstract: Microsphere optical nanoscope, as a competitive nano-imaging technique, has extensive applications in the semiconductor industry and biology due to its real-time imaging ability, label-free characteristics, and good compatibility with conventional microscopes. After years of rapid development, the microsphere optical nanoscope still faces restrictions on imaging resolution, contrast, magnification, and field-of-view. To further promote the imaging performance of the microsphere optical nanoscope, two new technical modification routes are developed. At single component level, engineered microspheres with enhanced nano-imaging ability, such as hyper-hemi-microsphere and bilayer-film-decorated microsphere, are put forward and realized through diverse nanofabrication techniques. At device level, substituting single microsphere with microsphere compound lens can improve imaging performance in multiple aspects, such as customized magnification and large field-of-view. Effectiveness of these modifications has been proved in semiconductor chip inspection and microfluidic dynamic nano-imaging. Furthermore, these technical advances pave way for a miniaturized all-microspheres nanoscope with an ultra-compact system configuration, which makes low-cost and portable optical nanoscopes feasible.

Full-field Vibration Measurement by LDV-enhanced Imaging Technology
Abstract: Vibration measurement, particularly the measurement of mode shapes, is crucial for structural dynamic analysis and defect localization because it helps validate finite element or analytical vibration models. Laser Doppler Vibrometry (LDV) and high-speed Digital Image Correlation (DIC) are the leading methods for experimental mode shape measurement. Unfortunately, the resolution of DIC is insufficient for detecting vibrations in normal structures. Similarly, the spatial sampling provided by LDV is limited. We have proposed a new full-field vibration measurement method that utilizes LDV-enhanced imaging technology with standard-rate cameras. This imaging technique could involve DIC or fringe/speckle projection. Our experiments demonstrate that the LDV spectrum can guide the removal of camera noise and significantly enhance the resolution of vibration measurements using imaging technology. The results of data fusion indicate that this method can effectively localize defects in various structures through vibration measurement.

Exploiting Spatiotemporal Priors for Motion-resolved Holographic Imaging
Abstract: Reference-free holographic imaging techniques have been long pursued because they obviate the high experimental requirements of conventional interferometric methods, but they are faced with an inherent trade-off between phase imaging fidelity and temporal resolution. Here, we propose a general algorithmic framework, termed spatiotemporally regularized inversion (STRIVER), for motion-resolved holographic reconstruction by exploiting spatiotemporal priors. Specifically, total variation with respect to the complex spatio-temporal datacube is introduced as a sparsity-promoting regularizer.
We experimentally demonstrate the use of spatiotemporal sparsity and implicit priors to obtain time-resolved holographic video of living organisms at a framerate-limited speed of over 100 Hz. STRIVER can also be potentially extended to other measurement schemes, spectral regimes, and imaging modalities, pushing the temporal resolution of computational imaging toward higher limits.
