Single-shot methods are applicable to dynamic objects but can only estimate sparse reconstructions and are sensitive to surface texture. This richly textured light comes with deeply embedded complexity, making the design, analysis, and recognition of such complex light patterns highly non-trivial. However, artifact-free super-resolution image reconstruction requires precise knowledge about the illumination parameters. Specifically, we sequentially obtain uniformly illuminated and structured light field images We call direct illumination the light which hits the scene coming directly from the projector, and global illumination any other light contributions including the ambient light. Object surfaces are illuminated with a known pattern of light. This method consists of modifying the illumination by superposing a well-defined pattern on either the sample itself or its image. A structured-light 3D scanner is a 3D scanning device for measuring the three-dimensional shape of an object using projected light patterns and a camera system. Mar 14, 2025 · Reconstruction algorithms are essential for structured illumination microscopy (SIM) chen2023superresolution as they extract high-frequency details from raw images captured under structured light illumination. Specifically, we sequentially obtain uniformly illuminated and structured light field images With our structured illumination microscopy platform, Creative Biostructure can provide sample preparation, data collection, and image analysis services to meet our customer’s requirements. In addition, the structured light sensor uses infrared light projection to obtain depth data, so it can also obtain the corresponding information for objects with less prominent texture features (Kuan et al. Implementing the robust classification is optional but we have found that the result improves without adding much decoding overhead. However, the imaging acquisition and reconstruction speeds limit its further applications. However, mobile SLI systems for 360 $^{\circ }$ 3D reconstruction demand 3D point cloud registration, involving high computational complexity. ( a , b ) While wide-field microscopy (a) results in the illumination of the whole field of view ( blue disk ) preventing Jan 29, 2021 · Till yet, QPM with structured illumination has been implemented using gratings or spatial light modulator (SLM), and the phase imaging modality is often isolated from other imaging modalities such as fluorescence imaging. Among super-resolution microscopy techniques, structured illumination microscopy (SIM) shows great advances in low phototoxicity, high speed, and excellent performance in long-term dynamic observation, making it especially suitable for live-cell imaging. It then uses the information about how the patterns appear after being distorted by the scene to eventually recover the 3D geometry. By introducing the constraint of epipolar geometry, we previously proposed real-time 3D reconstruction using lookup tables; however, we only knew these offline derived tables were the combinations of the elements in calibration matrices of a camera and a projector, and suffered A custom structured light pattern can be designed to fit the inspection needs, varying in illumination pattern features and divergence angle to modify the inspected surface area. However, conventional implementations often rely on mechanically or optoelectronically driven complex systems, limiting the compactness, stability, and integration. The structured light is generated with a digital micro-mirror Jul 7, 2024 · Structured illumination microscopy (SIM) is a type of fluorescence microscope that incorporates a structured light generation device, such as a grating, spatial light modulator, or digital micromirror device (DMD), into the illumination path. May 28, 2021 · Structured illumination microscopy (SIM) uses a relatively low illumination light power compared with other super-resolution microscopies and has great potential to meet the demands of live-cell imaging. SIM enhances image resolution beyond the diffraction limit of light, allowing scientists to explore biological structures and processes with remarkable clarity. Structured light illumination, scanning along both horizontal and vertical directions, achieves more robust accuracy. Structured light illumination is a process of 3D scanning using a digital projector to project a series of striped pat- terns that sweep a target surface, and based on the warping of the stripes Optical triangulation Project a single stripe of laser light Scan it across the surface of the object This is a very precise version of structured light scanning Good for high resolution 3D, but needs many images and takes time Feb 15, 2016 · A structured light scanning system projects different light patterns, or structures, and captures the light as it falls onto the scene. Aug 26, 2024 · The phase-shifting structured light illumination technique is widely used in imaging but often relies on mechanical translation stages or spatial light modulators, leading to system instability, low displacement accuracy, and limited integration feasibility.
