What Are the Key Techniques in Computational Imaging for Nanotechnology?
Several techniques are pivotal in computational imaging, particularly when applied to nanotechnology:
1. Super-Resolution Microscopy: This technique surpasses the diffraction limit of light to achieve nanometer-scale resolution. Methods like Structured Illumination Microscopy (SIM) and Stimulated Emission Depletion (STED) microscopy fall under this category.
2. Tomographic Reconstruction: Often used in electron microscopy, this technique reconstructs a 3D image from multiple 2D projections, allowing for detailed visualization of complex nanostructures.
3. Fourier Ptychography: This method enhances resolution by stitching together images taken from different angles and phases, using Fourier transformations to reconstruct a high-resolution image.
4. Machine Learning Algorithms: AI and machine learning are increasingly being used to enhance image reconstruction and analysis, making it possible to extract more information from noisy or incomplete data.
