Imaging cellular and extracellular structures and processes in situ and in vivo is highly
desired for the understanding and diagnosis of human diseases. High resolution optical …

Especially for displays, visible-wavelength lasers are in high demand for a wide range of
applications. Active research and development have been devoted to laser-based displays …

In this paper, we present a concept for speckle reduction using optical superposition instead
of temporal superposition. The proposed speckle reduction method does not contain any …

Optical coherence tomography (OCT) is a high-resolution and non-invasive optical imaging
technology, which is widely used in many fields. Nevertheless, OCT images are disturbed by …

An optical-fiber measurement system includes an optical system that generates light and a
spatial optical switch that is coupled to the optical system that processes the light generated …

A few-mode optical coherence tomography (FM-OCT) system was developed around a 2× 1
modally-specific photonic lantern (MSPL) centered at 1310 nm. The MSPL allowed FM-OCT …

摘要光学相干层析成像(OCT) 的图像质量会受到散斑噪声的影响, 限制了OCT
在临床诊断中的应用. 叠加取平均是一种降噪的常用方法, 作为相干噪声, 散斑降噪的关键在于 …

Speckle is an intrinsic noise of interferometric signals which reduces contrast and degrades
the quality of optical coherence tomography (OCT) images. Here, we present a frequency …

Optical coherence tomography (OCT) imaging is a technique that is frequently used to
diagnose medical conditions. However, coherent noise, sometimes referred to as speckle …

It is important to enhance the contrast and remove the speckle noise for optical coherence
tomography (OCT) images. In this paper, we propose a selective retinex enhancement …
