Compensation of spatial dispersion caused by the acousto-optic deflector (AOD) when using a femtosecond laser is difficult across whole scanning range system, and this significant impediment to its use. In conventional methods, AOD was compensated only it at particular position, while other positions, quality light beam reduced. We developed novel method for compensating within entire special Keplerian telescope. Our experimental results show that residual sufficiently, focal spots reach...

The performance of CCRT induces severe toxicities in HNSCC patients decreases the quality life (QOL). Maitake D-Fraction proteoglycan which has anti-tumor function associated with its immunomodulatory capacity. polysaccharides also have anti-radiation effect radiation therapy during cancer treatment. This research aimed to illustrate effects on CCRT-associated...
We propose a method to achieve high-resolution femtosecond laser beam shaping (HR-FLBS) via digital holography based on mirror device (DMD) and optimized optical design. By programming the hologram DMD, we captured several patterns such as light spots, decorated letters of "HUST" (Huazhong University Science Technology), series concentric annuli whose fine structure approaches diffraction limit. The experimental results confirm that proposed can shape amplitude phase arbitrarily with high resolution.
The acousto-optic lens (AOL) is becoming a popular tool in the neuroscience field. Here we analyzed deformation of diffraction beam after passage through an AOL consisting pair deflectors using both theoretical and experimental data. results showed that, because high sensitivity optical spatial frequencies deflectors, boundary strength decreases significantly. When focal length diminishes, becomes more serious with smaller size. This finally leads to decreased illuminative numerical...
Abstract Nucleic acids of intact biological tissues are rich in information. Whole‐mount situ hybridization is a powerful technique to mine the wealth data contained DNAs or RNAs, especially mRNAs. However, there no simple, rapid approaches precisely locate mRNAs whole‐mount such as brains. By combining penetration procedures iDISCO with signal amplification approach termed chain reaction, we herein developed method for whole‐brain at cellular resolution. Based on fluorescence tomography...

The two-photon microscope is a powerful tool in life science. Conventional microscopy can image only plane of particular axial position at time. Axial scanning get the volumetric information, but it gets signals from different positions serially, which means that exposure time every limited. Here we demonstrate novel method, to best our knowledge, simultaneously record images two planes xyz positions. demultiplexing signal realized using confocal strategy. experimental results show be used...
Large aberrations are induced by non-collimated light when the convergence or divergence of incident beam on back-pupil plane objective lens is adjusted for 3D non-inertial scanning. These significantly degrade focus quality and decrease peak intensity femtosecond laser focal spot. Here, we describe an aberration-corrected scanning method lasers based a digital micromirror device (DMD) that used both aberration correction. An imaging setup to detect spot in space, iterative optimization...
Multi-focus parallel scanning can effectively increase laser fabrication throughput. However, the conventional approach of using a spatial light modulator (SLM) to generate multi-foci and scan this fixed number foci with galvanometer scanners only achieve periodic trajectory due low switching speed SLM. Here we demonstrate multi-focus non-periodic method for femtosecond lasers by using, instead, fast-switching digital micromirror device (DMD) dynamic foci. The effective is quickly switched...
