WebJun 7, 2024 · Point spread function (PSF) engineering is an important technique to encode the properties (e.g., 3D positions, color, and orientation) of a single molecule in the shape of the PSF, often with the help of a programmable phase modulator. WebSep 16, 2024 · For object points that are not on the optical axis, the PSF is translated such that it is centred on the ideal Gaussian image point. Usually we assume that we know the field transmitted or reflected by an object in the socalled object plane, which is the plane immediately behind the object (on the side of the lens).
