Creation of a tight PSF array for scanning structured illumination via phase retrieval
نویسندگان
چکیده
In this work, we propose a structured illumination (SI) method based on a twophoton excitation (TPE) scanning laser beam. Advantages of TPE methods include optical sectioning, low photo-toxicity, and robustness in the face of sample induced scattering. We designed a novel multi-spot point spread function (PSF) for a fast, two-photon scanning SIM microscope. Our multi-spot PSF is generated with a phase retrieval algorithm. We show how to obtain the phase distribution and then simulate the effect of this distribution on a spatial light modulator (SLM), which produces the multi-spot PSF in the object plane of the microscope. We produce simulations that show the viability of this method. The results are simulated and a multi-spot PSF scanning SIM microscope is proposed.

متن کاملAmine Based CO2 Absorption in Membrane Contactor Using Polyvinyl Pyrrolidone-modified Polysulfone Flat Sheet Membrane: Experimental Study and Mass Transfer Resistance Analysis
Membrane contactor using amine based absorbents is an efficient technology for CO2 separation from gaseous mixtures. A novel porous polysulfone (PSF) flat membrane was prepared via non-solvent phase inversion method. The PSF membrane was modified by adding polyvinyl pyrrolidone (PVP) to the dope solution. The fabricated membrane was used in the serpentine flow field contactor module for CO2 abs...
متن کاملPreparation of blend hydrophilic PSF-SPEEK ultrafiltration membranes for oily wastewater treatment
Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...
متن کاملStructured Illumination by a Pinhole Array for Holographic Microscopy
The structured illumination of samples is known as one of the techniques for sub diffraction optical microscopy [1-3]. A spatial resolution beyond the optical diffraction limit is achievable by using nano light spots for scanning of the sample. We apply the structured illumination for digital inline holographic microscopy [4-6]. The structured illumination patterns are superposed by that of the...
متن کاملSpatial light modulators in fluorescence microscopy
Spatial light modulators (SLMs) are becoming increasingly important in optical microscopy. These reflective or transmissive devices, based on microdisplays using liquid crystal or micromirror array technology, are used to achieve a variety of useful effects and imaging modes. When placed in an image plane, SLMs can be used to create arbitrary, computer controlled masks. These masks can then be ...
