As a result of further experiments we have found that the explanation of the effect given requires some modification. One of the images is due to reflection from the surface of the sphere instead of to internal reflection. As was suggested to us by Prof. Tyndall, this can be seen by ...

When the red laser illuminates the lyosol, the Tyndall effect will form a light path with a certain distance, and the optical properties of the lyosol will have a certain influence on the Tyndall light intensity. This paper mainly aims at the theoretical and experimental studies on the change...
In order to verify the analytical solutions introduced in Section 2, we conducted a number of experiments to measure the shielding effect of stainless steel rods. The details of each rod can be seen in Table 1. In contrast to the magnetic field used for magnetic tracking, the magnetic field...
(SPC) and time-gated imaging have been dominated by photo-cathode based intensifier techniques achieving high signal amplification through the "photo-intensification" of the generated electron cascade through the photo-electric effect using existing charge-coupled device (CCD) and CMOS image sensors (...
early attempts to put the photophone into practical use, mainly for military communications [6], it was not until 1938 that Veingerov developed the first widely accepted implementation of the phenomenon, which he called method for gas analysis based on Tyndall-Röntgen optic-acoustic effect [7,...
During the period close to the excitation, it is more probable for the pixel array to detect photons, so the pile-up effect is more apparent and the counts error increases. After a while, the probability of photon detection falls, so the distribution gradually approaches to single-exponential ...
