Optical tomography with structured illumination.
We consider the image reconstruction problem for optical tomography with structured illumination. A fast image reconstruction algorithm is proposed that reduces the required number of measurements of the optical field compared to methods that utilize point-source illumination. The results are illustrated with numerical simulations.
متن کاملExact Wavefront Correction in Adaptive Optics
In this work we consider an adaptive optical system in which a deformable mirror is controlled to compensate for random wavefront disturbances. For most systems of this type, the shape of the mirror is taken as a linear function of the wavefront error, leading to satisfactory results in linear regimes. Here, the geometric shape of the mirror leading to a perfect correction of the wavefront is d...
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 کاملHolographic Wavefront Sensor
There are several different types of wavefront sensors that can be used to measure the phase of an input beam. While they have widely varying modes of operation, they all require some computational overhead in order to deconstruct the phase from an optical measurement which reduces the sensing speed. Furthermore, zonal detection methods, such as the Shack-Hartmann wavefront sensor (SHWFS) are n...
متن کاملAdaptive illumination reduces photobleaching in structured illumination microscopy.
Photobleaching is a major factor limiting the observation time in fluorescence microscopy. We achieve photobleaching reduction in structured illumination microscopy (SIM) by locally adjusting the illumination intensities according to the sample. Adaptive SIM is enabled by a digital micro-mirror device (DMD), which provides a projection of the grayscale illumination patterns. We demonstrate a re...
