“…An alternate strategy can be deployed for mimicking coherent scatting and holographic imaging with incoherent emitters based on the interference of spatially coherent illumination light, either between a plane wave and a point focus [54,55] or with a pair of plane waves [56][57][58][59][60][61]. By using the interference between two spatially coherent illuminating plane waves, one may perform tomographic imaging with fluorescent emitters that exactly mimics ODT [62][63][64][65].…”

A full derivation of the recently introduced technique of Harmonic Optical Tomography (HOT), which is based on a sequence of nonlinear harmonic holographic field measurements, is presented. The rigorous theory of harmonic holography is developed and the image transfer theory used for HOT is demonstrated. A novel treatment of phase matching of homogeneous and in-homogeneous samples is presented. This approach provides a simple and intuitive interpretation of coherent nonlinear scattering. This detailed derivation is aimed at an introductory level to allow anyone with an optics background to be able to understand the details of coherent imaging of linear and nonlinear scattered fields, holographic image transfer models, and harmonic optical tomography.

“…Here we summarize the analysis of the SPIFI signals presented in Refs. 26 and 38 and account for second order multiphoton imaging as in two-photon excitation fluorescence (2PEF) or second harmonic generation (SHG). For simplicity, the mask equation is written with a time dependent spatial frequency fr(t) as M(r,t)=12{1+cos[2πfr(t)r]}.…”

“…Since SPIFI was first introduced as an imaging technique, 22 it has been demonstrated and extended to multiple imaging modalities including fluorescent imaging, 22,23 multiphoton excitation fluorescence imaging, [24][25][26] second harmonic generation imaging, 26,27 phase imaging, 28,29 and localization microscopy. 30 Extending SPIFI to provide simultaneous SIM benefits in two dimensions has also been explored using 2D modulation schemes, 31,32 random-access imaging, 33 parallel line image acquisition, 34 single pixel tomographic imaging, [35][36][37][38] multi-cursor 2D imaging, 32 random access multiphoton imaging, 33 and coherent anti-Stokes Raman spectroscopy. 27 Here we introduce a system that employs SPIFI in two domains to (1) achieve enhanced resolution multiphoton microscopy and (2) compensate for second order dispersion with a rapid, facile, and easily repeatable method.…”

.SignificanceMultiphoton microscopy is a powerful imaging tool for biomedical applications. A variety of techniques and respective benefits exist for multiphoton microscopy, but an enhanced resolution is especially desired. Additionally multiphoton microscopy requires ultrafast pulses for excitation, so optimization of the pulse duration at the sample is critical for strong signals.AimWe aim to perform enhanced resolution imaging that is robust to scattering using a structured illumination technique while also providing a rapid and easily repeatable means to optimize group delay dispersion (GDD) compensation through to the sample.ApproachSpatial frequency modulation imaging (SPIFI) is used in two domains: the spatial domain (SD) and the wavelength domain (WD). The WD-SPIFI system is an in-line tool enabling GDD optimization that considers all material through to the sample. The SD-SPIFI system follows and enables enhanced resolution imaging.ResultsThe WD-SPIFI dispersion optimization performance is confirmed with independent pulse characterization, enabling rapid optimization of pulses for imaging with the SD-SPIFI system. The SD-SPIFI system demonstrates enhanced resolution imaging without the use of photon counting enabled by signal to noise improvements due to the WD-SPIFI system.ConclusionsImplementing SPIFI in-line in two domains enables full-path dispersion compensation optimization through to the sample for enhanced resolution multiphoton microscopy.

“…By exploiting the TOF of photoacoustic wave, the depth resolution of 3D SPI can be improved for microscopic imaging but restricted to acoustic diffraction limit ( 18 ). Alternatively, by single-pixel diffraction tomography ( 38 , 39 ), holographic imaging together with a sample rotation enables volumetric reconstruction of a 3D object. However, the imaging operation relies on the stability of mechanical rotation as well as the ability to position the sample precisely at the microscope focus, which inevitably limits the applicability in microscopic imaging.…”

Three-dimensional single-pixel imaging (3D SPI) has become an attractive imaging modality for both biomedical research and optical sensing. 3D-SPI techniques generally depend on time-of-flight or stereovision principle to extract depth information from backscattered light. However, existing implementations for these two optical schemes are limited to surface mapping of 3D objects at depth resolutions, at best, at the millimeter level. Here, we report 3D light-field illumination single-pixel microscopy (3D-LFI-SPM) that enables volumetric imaging of microscopic objects with a near-diffraction-limit 3D optical resolution. Aimed at 3D space reconstruction, 3D-LFI-SPM optically samples the 3D Fourier spectrum by combining 3D structured light-field illumination with single-element intensity detection. We build a 3D-LFI-SPM prototype that provides an imaging volume of ∼390 × 390 × 3,800 μm 3 and achieves 2.7-μm lateral resolution and better than 37-μm axial resolution. Its capability of 3D visualization of label-free optical absorption contrast is demonstrated by imaging single algal cells in vivo. Our approach opens broad perspectives for 3D SPI with potential applications in various fields, such as biomedical functional imaging.
