Abstract: The invention relates to a method and apparatus for conducting light onto cuvettes in a photometer. Onto each cuvette in a row, there is successively conducted light through a moving light-cutting disc (8), which is provided with a slot (10) at each light path. Thus the light passing through the adjacent cuvette does not disturb the measurement.

Abstract: A method for separating diamonds from associated gangue in a diamondiferous material. The method comprises the steps of mixing the diamondiferous material with water to form a slurry and passing the slurry through laser radiation of known wavelength in the infra red part of the electromagnetic spectrum to cause Raman spectral scattering of the radiation from the slurry. The scattered radiation is collected and filtered to isolate diamond-relevant radiation and the filtered radiation is analyzed to determine whether it is indicative of the presence of diamond. Finally, on the basis of such analysis, high diamond content slurry is separated from low diamond content slurry.

Abstract: In each configuration, at least one TDI sensor is used to image the portions of interest of the substrate that are substantially uniformly or critically illuminated. In one configuration, the substrate is compared to the expected characteristic features prestored in memory. In a second configuration, a first and second pattern in a region of at least one substrate are inspected by comparing one pattern against the other and noting whether they agree with each other. This is accomplished by illuminating the two patterns, imaging the first pattern and storing its characteristics in a temporary memory, then imaging the second pattern and comparing it to the stored characteristics from the temporary memory. Then the comparisons continue sequentially with the second pattern becoming the first pattern in the next imaging/comparison sequence against a new second pattern. With each comparison whether there has been agreement between the two patterns is noted. After all of the patterns are sequentially compared, the bad ones are identified by identifying those that did not compare with other patterns in the test process. This inspection technique is useful for doing die-to-die inspections, as well as repeating patern inspections within the same die. A variation of the second configuration uses two TDI sensors to simultaneously image the first and second patterns eliminating the need for the temporary memory.

Abstract: A system for detecting optically-sensitive properties of sheet materials during manufacture includes a first group of bundles of optical fibers that convey light to selected transmitting locations adjacent one face of the sheet material. The system further includes a second group of bundles of optical fibers that collect and convey light transmitted through the sheet material to a light detector. The light detector measures the intensity of light received from each of the bundles of the second group to provide measurements of optically-sensitive properties of the sheet material at selected cross-directional locations.

Abstract: A method may include determining a thermal signal for a thermal analysis of a rock sample. The method may further include transmitting various commands to various thermal sources to produce various heat emissions. A respective command among the commands may cause a respective thermal source among the thermal sources to produce a respective heat emission based on the thermal signal. The method further includes determining distributed temperature data of the rock sample using various distributed temperature sensors in response to producing the heat emissions. The distributed temperature sensors may be coupled to the rock sample on a first rock surface and a second rock surface. The first rock surface may be on an opposite side of the rock sample from the second rock surface. The method may further include determining predicted thermal property data of the rock sample using the distributed temperature data and a machine-learning model.

Abstract: One pixel unit including at least one light receiving element of a light receiving element array (photodiode array) and a light source have a one-to-one correspondence, and only when the light source emits light, the light beam is detected by at least one light receiving element (one pixel unit) corresponding to the light source. An illumination optical system includes a light guiding means for guiding to an inspection object by reducing an interval between optical axes of light beams emitted from a plurality of light sources in an arrangement direction of a plurality of the light sources.

Abstract: Systems and methods for imaging cells. Quantitative phase imaging uses variations in the index of refraction of a sample as a source of endogenous contrast, providing label-free information of sub-cellular structures and allowing for the reconstruction of valuable biophysical parameters, such as cell dry-mass at femtogram scales, mass transport, and sample thickness and fluctuations at nanometer scales. As a result, QPI has become a valuable tool in biology and medicine. However, QPI has suffered from the need for trans-illumination through relatively thin objects in order to gain access to the forward-scattered field, which carries crucial low spatial frequency information of a sample and avoid contributions from multiple scattered light or out-of-focus planes. The disclosed methods and systems can provide for reconstruction of QPI and corresponding analysis for imaging samples of cells in thick samples using an epi-illumination configuration.
