Sidelobe reduction of limited diffraction beams with Chebyshev aperture apodization
نویسندگان
چکیده
A limited diffraction beams ~LDB! imaging system with Chebyshev weighting is presented. The objective of the paper is to reduce the sidelobes of the LDB without impacting on main-lobe performance and increase the contrast-resolution of the imaging system. The Chebyshev weighting is applied to the LDB and an analytic description and the simulation results are obtained. Theoretical analysis and simulation results show that the LDB with Chebyshev weighting can reduce sidelobes, and improve imaging system performances. © 2000 Acoustical Society of America. @S0001-4966~00!04605-1#

Pupil phase apodization for imaging of faint companions in prescribed regions
We consider the ‘faint companion’ problem where substantial reduction of diffraction sidelobes is required in order to image a faint neighbour near a much brighter source. In addition to well-known pupil amplitude and shape apodization methods, we found that the required sidelobe reduction can be obtained by appropriate spatial phase modulations over an aperture. Here, our previous results on o...
متن کاملSidelobe Reduction of Images with Coded Limited Diffraction Beams
Limited diffractlon beams were first described by Stratton [l] and then produced experimentally by Dumin in optics [2]. Bessel beams [1,2], X waves [3,4], and bowtie beams [5] are just a few examples of the limited diffract~on beams. Theoretically, these beams have an infinite depth of field, i.e., they can propagate to Infinite dlstance without spreading. In practice, when produced with a fini...
متن کاملLow sidelobe limited diffraction beams in the nonlinear regime.
In linear propagation, sidelobe levels of Bessel limited diffraction beams are only about 8 dB down relative to the mainlobe. In the nonlinear regime, these beams will have a region near the source where the side-lobe level of the second harmonic is 16 dB down, but this region has usually been considered to be so small that it is of little practical interest. In this paper it is shown that when...
متن کاملPupil phase apodization for achromatic imaging of extra-solar planets
Direct imaging of extra-solar planets in the visible and infrared region has generated great interest among scientists and the general public as well. However, this is a challenging problem. Difficulties of detecting a planet (faint source) are caused, mostly, by two factors: sidelobes caused by starlight diffraction from the edge of the pupil and the randomly scattered starlight caused by the ...
متن کاملNon-linear propagation of limited diffraction beams
Recently, harmonic imaging has been shown to increase image quality in medical imaging. This is believed to be caused by decreased sidelobes. It is also due to a decreased sensitivity to near-field aberrations owing to the lower transmission frequency, and the lower relative amplitude of the second harmonic in the near-field. One of the problems of limited diffraction beams has been the sidelob...
