Flexible, and easy-to-use Python diffraction simulator that focuses on visualizing physical optics phenomena. The simulator uses mainly scalar diffraction techniques for light propagation, provides a ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...

IMPACT is a new framework for sound speed estimation and distributed aberration correction in medical ultrasound imaging. Our previous work (see https://github.com ...

Abstract: The intermediate angular-spectrum method is an efficient way to calculate computer-generated holograms without zero-padding and cropping operation. In this paper, we present an optimized ...

Elastic full waveform inversion (EFWI) is a powerful technique. However, its strong non-linearity makes it susceptible to converging towards local extremes during the iterative process due to various ...

In this letter, we address the problem of phase-only transmit beamforming to generate a wide beam with an almost flat mainlobe for phased arrays. Instead of resorting to time-demanding optimization ...

Abstract: Angular superresolution technique is of great significance in enhancing the azimuth resolution when the real aperture is constrained. Recently, based on weighted least squares (WLS), the ...

Holographic optical tweezers use focused light to manipulate multiple objects independently without contact. They are used in tasks such as measuring the spring constant of DNA, the pulling force of ...
