With a decreasing zone width, diffraction effects become noticeable. The diffracted pattern is no longer an ideal FZA pattern. To observe the diffraction phenomena, a white collimating LED light is adopted to illuminate the FZA mask. The FZA pattern with r1 = 0.32 mm and the corresponding ...
The slit was cut long to let in much light and narrow to stop the bad weather. 口子开得长,为的是让多的阳光照进屋内;开得窄,使屋内不受不良天气影响。 10. 24kb There will therefore be very little diffraction parallel to the edges of the slit. 因此,在平行于狭缝两端边界的方向上,几乎没...
Each diffraction-limited emission location is subsequently examined by analyzing time-domain intensity fluctuations, to demonstrate that the emission originates from a single QD, rather than from QD aggregates. We demonstrate that the PC multi-enhancements are responsible for amplification of the QD emi...
to grow efficiently a titled single crystal by irradiating an X-ray to the revolving crystal under growth, and pattern-recognizing the diffraction of a white light and characteristic X-rays scattered by the surface of the crystal with a device capable of detecting two-dimensionally the diffraction...
Moreover, transmission electron microscopy (TEM) and selected-area electron diffraction (SAED) were performed on one nanowire (Figure 2G). The TEM image shows the straight boundary of the nanowire. As shown in the SAED pattern (Figure 2F inset), the circled SAED spot with the d-spacing of ...
," and that the droplet's normally straight trajectory deviated when passing through the slit. The remarkable feature was that even with identical initial conditions, the deviation of a given individual walker appeared random, while the deviation of many walkers revealed an interference pattern....

interference intensity in the form of a petal pattern with the number of petals being 2\(\left| l \right|\) = 8. SLM: spatial light modulator; SF: spatial filter; DM: dichroic mirror; BBO: type-I beta barium borate crystal; T: translation stage...
(see supplementary methods)30. Here, we demonstrate ×2.3 resolution enhancement in Fig.4c, i.e., beyond the diffraction limit, with a 100-nm nanoblock. The nanostructure exhibits a strong nonlinear response (saturation of scattering in Fig.2a). With a Gaussian focus, the nonlinear response ...
