.A configuration for the measurement of thickness changes in materials through one-shot digital speckle pattern interferometry (DSPI) was developed. The phase maps calculation was made by adding carrier fringes by the multiple aperture principle and Fourier Transform Method (FTM). With this setup, interferometry configurations verified that the simultaneous and instantaneous visualization of two opposite faces of a surface is possible. In addition, the combination of the simultaneous results obtained from both sides of the material makes it possible to determine displacements with greater sensitivity or to identify changes in their thickness. The validation and demonstrative tests were carried out with a 1-mm-thick aluminum plate with a 5-mm diameter through hole coated. Thickness changes to 2 μm were measured.

“…For spatial methods of 3D deformation measurement, three different spatial carrier frequencies are introduced into the interference system, and Fourier transform (FT) method serves as a competing procedure for fringe pattern analysis 7 – 9 According to the Nyquist theorem, the spatial frequency must be at least twice that of the measured deformation, which limits the measuring range. Another disadvantage of FT for 3D deformation simultaneous measurement is the need for individually adapted filters in the spatial frequency domain.…”

A simple and effective phase-shift device is designed for the simultaneous and highaccuracy measurement of three-dimensional (3D) deformation using tri-wavelength electronic speckle pattern interferometry and a three-sensor charge-coupled device camera. The designed phase-shifter can provide tri-wavelength lasers quasi-π∕2 phase-step simultaneously. Multi-component phases related to 3D deformation information are extracted by a 90 deg step 4-frame technique from the separated red, green, and blue channels of color images. Six derivative components are further determined based on the retrieval phase maps. Experimental results demonstrate the validity and feasibility of the proposed method.

“…Holographic multiplexing permits recovering multiple complex wavefronts in a single camera acquisition by integrating several object waves into one single spatially multiplexed hologram. − The single-shot capability and the compatibilities with various holographic imaging devices of holographic multiplexing allow for high temporal-resolved optical imaging applications such as ultrafast pulse holography, , single-step synthetic-aperture holography, − high-speed holographic tomography, and snapshot multispectral imaging . Holographic multiplexing-based large-FOV quantitative phase imaging (QPI) methods increase the SBP without compromising other imaging parameters, such as temporal resolution. − Despite these advantages, these methods also present certain limitations.…”

High-throughput microscopic imaging is highly desirable in biomedical applications. Advances in computational microscopy have achieved high space-bandwidth products and even permitted gigapixel imaging in a stepwise fashion, yet temporal resolution remains challenging for investigating live-sample dynamics. Here, we report multibeam array interferometric microscopy (MAIM) for a single-shot high space-bandwidth product. The MAIM method overcomes the limitations of conventional digital holographic microscopy, providing complex field reconstruction with a maximum 5-fold field of view (FOV) increase in a single camera acquisition, while maintaining sub-nanometer optical path-length stability. This is achieved by integrating common-path holographic microscopy, multibeam interference technology, and holographic multiplexing technology. The temporal resolving power of MAIM is significantly higher than that of computational illumination microscopy. MAIM has major advantages over previous holographic multiplexing techniques in that it integrates more wavefronts and offers high temporal stability. The fundamentals of MAIM are analyzed theoretically. As a demonstration, we build MAIM prototypes to increase the FOV by factors of 5, 4, and 3, respectively. We present proof-of-concept MAIM imaging results of both natural and artificial samples and show biomedical applications such as monitoring sub-cellular dynamical phenomena in flowing live erythrocytes in vitro and label-free microrefractometry imaging of unstained cancer tissue slices. MAIM gives rise to (ultra)fast or long-term (time-lapse) imaging of nanoscale dynamics of unstained live samples in vitro with a high throughput.
