DOI: 10.1016/j.optlaseng.2019.105845
Abstract: Abstract This paper describes a speckle suppression method using flexible diffractive optical elements (DOEs) based on binary random sequences with tracked motion. The DOE loops consist of 1D random-sequence diffractive structures with similar but different… read more here.

DOI: 10.1093/mnras/stw2544
Abstract: Residual speckles due to aberrations arising from optical errors after the split between the wavefront sensor and the science camera path are the most significant barriers to imaging extrasolar planets. While speckles can be suppressed… read more here.

DOI: 10.1364/ao.57.008851
Abstract: Using a laser light source in imaging devices provides a wide color gamut, high brightness, resolution, and efficiency. At the same time, it creates a speckle pattern that deteriorates the image quality. This paper is… read more here.

DOI: 10.1364/oe.401679
Abstract: The spherical computer-generated hologram is inevitably suffered from the speckle noise since it is necessary to add random phase to the object to ensure the scattering characteristic of reconstructed image. The speckle noise seriously degrades… read more here.

DOI: 10.1515/nanoph-2020-0390
Abstract: Abstract Fast speckle suppression is crucial for time-resolved full-field imaging with laser illumination. Here, we introduce a method to accelerate the spatial decoherence of laser emission, achieving speckle suppression in the nanosecond integration time scale.… read more here.
