WebFeb 1, 2013 · During LSF, a laser beam generates a molten pool on the substrate and alloy powders were fed into the molten pool by a powder feeding system. The powders were melted rapidly under the irradiation of laser beam, and a cladding point was formed when the laser beam moved away. WebSep 9, 2013 · We have built a light-sheet microscope that uses remote focusing with an electrically tunable lens (ETL). Without moving specimen or objective we have thereby achieved flexible volume imaging at much higher speeds than previously reported. Our high-speed microscope delivers 3D snapshots of sensitive biological samples. how do you spell fathom https://boutiquepasapas.com

The optical transfer function is not only useful for the design of optical system, it is also valuable to characterize manufactured systems. The optical transfer function is defined as the Fourier transform of the impulse response of the optical system, also called the point spread function. The optical transfer function is thus readily obtained by first acquiring the image of a point source, and applying the two-dimensional discret… WebHere is my algorithm to get MTF. 1. get Image 2. select ROI (High contrast region) 3. extract a center line out of image array. 4. differentiate the pixel value 5. apply fast Fourier transform and...

WebMetalens Design. When designing a metalens it is necessary to choose a geometrical property of the unit cell that will be varied to achieve a certain target in the optical response.
