The ultrafast time-stretch microscopy based on a single-pixel detector has become a hotspot of the research, owing to its high sensitivity compared to those pixel sensors. However, gigahertz or tens of gigahertz acquisition bandwidth is required for this scheme, resulting in great expense for the whole imaging system and hindering its wide applications. In this Letter, a dual-comb asynchronous optical sampling is applied for the conventional time-stretch microscopy, whose ultrafast temporal axis is magnified by 9200 times. The acquisition bandwidth requirement is thus greatly relaxed, and 320 kHz bandwidth successfully resolves 2.3 μm spatial resolution with tens of kilohertz frame rate.

We experimentally demonstrate a dual frequency comb based transient absorption (DFC-TA) technique, which has a 12 fs time resolution and an ultrafast scan rate. Here, the fast scan rate is achieved by...
The performance of ultrafast time-stretch imaging at long wavelengths (beyond 1.5 μm) has suffered from low detection sensitivity due to the increasing loss of optical dispersive fibers. Here, we re...
The mechanism of Cooper pair formation and its underlying physics has long occupied the investigation into high temperature (high-T ) cuprate superconductors. One of the ways to unravel this is to obs...
Studies of the ultrafast carrier dynamics of transition metal dichalcogenides have employed spatially-averaged measurements, which obfuscate the rich variety of dynamics that originate from the struct...
Breaking the resolution limit of conventional microscopy by super-resolution microscopy (SRM) led to many new biological insights into protein assemblies at the nanoscale. Here we provide detailed pro...

This study will be the first randomized controlled trial of Comprehensive Behavior Modification (ComB) as a treatment of trichotillomania (TTM). ComB treatment (12 weekly sessions, followi...
Stretch marks (striae distensae) are a form of scarring that is a natural result of pregnancy, obesity and in some instances occur due to puberty or steroid use. For some people, the stret...

This study intends to carry out a prospective, randomized controlled trial to research and development a new invivo microscopy based on the technology which is combined with high-definitio...
Stretch receptors found in the bronchi and bronchioles. Pulmonary stretch receptors are sensors for a reflex which stops inspiration. In humans, the reflex is protective and is probably not activated during normal respiration.
Microscopy in which the samples are first stained immunocytochemically and then examined using an electron microscope. Immunoelectron microscopy is used extensively in diagnostic virology as part of very sensitive immunoassays.
Scanning microscopy in which a very sharp probe is employed in close proximity to a surface, exploiting a particular surface-related property. When this property is local topography, the method is atomic force microscopy (MICROSCOPY, ATOMIC FORCE), and when it is local conductivity, the method is scanning tunneling microscopy (MICROSCOPY, SCANNING TUNNELING).
Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.
Exercises in which muscles are repeatedly and rapidly stretched, followed by shortening, concentric MUSCLE CONTRACTION (e.g. jumping and rebounding). They are designed to exert maximal force in minimal time by increasing STRETCH REFLEX.
