Fast generation of arbitrary optical focus array

چکیده
We report a novel method to generate arbitrary optical focus arrays (OFAs). Our approach rapidly produces computer-generated holograms (CGHs) precisely control the positions and intensities of foci. This is achieved by replacing fast Fourier transform (FFT) operation in conventional iterative Fourier-transform algorithm (IFTA) with linear algebra one, identifying/removing zero elements from matrices, employing generalized weighting strategy. On premise accelerating calculation speed >70 times, we demonstrate OFA 99% intensity precision experiment. proves effective applicable systems which real-time generation essential.

Optical arbitrary waveform generation
nature photonics | VOL 4 | NOVEMBER 2010 | www.nature.com/naturephotonics Although the electromagnetic spectrum is a continuum, a strong distinction is typically drawn between electronics and optics. This distinction is due, in part, to the very different technologies used for electronics and optics. A further distinction is that electronic devices typically generate and measure electric field ...
متن کاملDynamic optical arbitrary waveform generation and measurement.
We introduce a dynamic optical arbitrary waveform generation (OAWG) technique that produces bandwidth scalable, continuous waveforms of near perfect fidelity. Additionally, OAWG's complement, real-time arbitrary optical waveform measurement (OAWM) is discussed. These approaches utilize gigahertz-bandwidth electronics to generate, or measure, truly arbitrary and dynamic optical waveforms scalabl...

We describe the precise shaping and mode-resolved amplitude and phase characterization of optical arbitrary waveforms by using a 20 GHz optical frequency comb and integrated 64 20 GHz channel arrayed waveguide grating pair. Complex waveforms with large variations in phase and amplitude between adjacent modes were generated and characterized. © 2007 Optical Society of America OCIS codes: 320.710...
متن کاملFast optical thresholding with an array of optical thyristor differential pairs
In this paper an optoelectronic system for fast grey-level image decomposition into binary slices is presented. To perform thresholding we take advantage of the differential nature of optical thyristors and compare the light level of the image pixels with that of a reference intensity. For the input a grey-level image was generated using a liquid crystal spatial light modulator (SLM) and, for t...
