Title: Innovations of Peng Xi in Super-Resolution Microscopy

Introduction

Peng Xi is a prominent inventor based in Beijing, China, known for his contributions to the field of super-resolution microscopy. With a total of 2 patents, he has developed innovative methods that enhance imaging techniques in scientific research.

Latest Patents

One of his latest patents is a direct structured illumination microscopy (dSIM) reconstruction method. This method involves extracting a time domain modulation signal through a wavelet, converting an incoherent signal into a coherent one, and calculating an accumulation amount at each pixel. The result is a super-resolution image generated by utilizing the correlation between signals at different spatial positions. The dSIM algorithm is particularly notable for its insensitivity to reconstruction parameter errors and its ability to bypass complex frequency domain operations, thus preventing artifacts caused by parameter errors.

Another significant patent is related to a stimulated-emission-depletion (STED) super-resolution microscope. This invention includes various components such as an excitation light source, a depletion light source, and a Bessel beam generating system. The depletion light, which can be a first-order Bessel beam, exhibits anti-scattering and self-healing characteristics, improving image resolution in deeper regions of samples. This invention simplifies experimental operations compared to conventional STED microscopes and is more cost-effective than adaptive optical systems.
