摘要： Technologies are generally described for spectroscopic determination of one or more optical properties of a gemstone. An imaging device may include one or more light sources configured to illuminate one or more portions of the gemstone, and one or more photo detectors configured to detect reflected light from the portions of the gemstone in response to the illumination. An analysis module may be communicatively coupled to the imaging device, and configured to analyze the reflected light to determine the optical properties of the portions of the gemstone. The optical properties may include at least one of a clarity, color, fluorescence, birefringence, dichroism, and brilliance of the portions of the gemstone. In some examples, an optical fingerprint of the gemstone may be created based on one or more determined optical characteristics of the portions of the gemstone, where the optical fingerprint may uniquely identify the gemstone.

摘要： Cell culturing and tracking systems using an array of organic light emitting diodes (OLEDs) to illuminate cells and/or other particles in a cell chamber are described. Compared to conventional light sources, the OLED array consumes very little energy and emits a small amount of waste heat, so it may be disposed near or on the cell chamber. For instance, it can be printed on one side of the cell chamber itself. In addition, the OLED array may be patterned into pixels or sub-pixels (individual OLEDs), each of which is as small as or smaller than an individual cell or particle. Because the pixels are so small, OLED illumination can be used to acquire images with a spatial resolution equal to or better than the cell or particle cell. As a result, the OLED array can be used to track, monitor, identify, and manipulate individual cells within the cell culture.
