摘要： An optical analysis of saliva or a fluid-saliva mixture is performed in order to check whether the saliva or fluid-saliva mixture contains blood, which allows for determining whether or not a person may suffer from gingivitis or another condition affecting gum health. Light received from a representative volume of fluid (23) containing saliva is detected and analyzed. The analysis involves determination of at least one measurement value of light received by a light-receiving unit (25) for only a single wavelength of the light, particularly a wavelength that is associated with high absorption by a constituent of blood. It this respect, it is practical if the light-receiving unit (25) is configured to receive reflected light back from the volume of fluid (23). The optical analysis may be performed real-time during an action in a person's mouth involving a gum agitation effect, or after such action has taken place, for example.

摘要： A method for monitoring the production of a material (18,20) such as graphene in a liquid dispersion (14) in real time, comprises supplying the liquid dispersion to a fluid gap (106) defined between a first layer (101) and an opposed second layer (102), wherein the first layer (101) is light-transmissive and wherein the second layer (102) has a diffusely reflective surface (102a) facing the first layer. The diffusely reflective surface (102a) is illuminated with light from a light source (210) and light reflected from the diffusely reflective surface is detected at an associated photodetector (220). A light path from the light source to the photodetector comprises the light passing through the transmissive layer (101) towards the diffusely reflective surface (102a) through the fluid gap (106), reflecting off the diffusely reflective surface and passing back through the fluid gap towards and onwards through the transmissive layer. The concentration of the material (18,20) in the liquid dispersion (14) can be determined from the detected reflected light (234). The fluid gap (106) is typically an integral part of apparatus for producing the material, such as being formed between an inner rotor (102) and an outer casing wall (101) of a liquid exfoliation apparatus (100).

摘要： A material testing system can be used for measuring material properties. The system can include an inner cell and an outer cell that cooperate to at least partially define a first internal volume. The inner cell can at least partially define a second volume therein and is configured to receive a material sample. A first plurality of cameras that are configured to detect visible light surround the circumference of the inner cell. A second plurality of cameras that are configured to detect infrared light surround the circumference of the inner cell. A thermocouple can provide a reference temperature to calibrate thermal data from the second plurality of cameras. The first plurality of cameras, the second plurality of cameras, and the thermocouple can provide data to a computing device. A pattern on the material sample can enable the computing device to track movement of discrete points on the material.
