Abstract: An apparatus for emulating various known night sky illumination conditions. The apparatus comprises a plurality of electrically-powerable LEDs which are disposed in an array and have respective spectral curves centered at different wavelengths in the visible to the short wave infrared wavebands, and means for fixing the temperatures of the LEDs to avoid temperature-induced changes in their spectral curves. Additionally, the apparatus includes means for varying the light intensities of the individual LEDs so that the combination of their spectral curves matches the spectrum of the known night sky illumination condition to be emulated, and means for regulating the total amount of light collected from the array so that the cumulative spectrum has the same intensity as the known night sky illumination condition to be emulated.

Abstract: A divided pulse nonlinear optical source may be generated by combining nonlinear wave generation techniques with pulse division that can divide a parent pulse into N divided pulses, each divided pulse separate temporally. The N divided pulses can be passed into a nonlinear optical medium to generate an output. The output can include at least one output pulse for each divided pulse. The center wavelengths of each output pulse can be tuned so that each may have a center wavelength that is the same as, or differs from, each other output pulse. In some embodiments, the output pulses may be combined to generate the output. The output can be power scalable and wavelength tunable.

Abstract: Optical analysis systems and methods may be used for analyzing the characteristics, including compositions, of cement additives, which may be used in formulating a cement slurry. For example, a cement additive may be optically interacting with an integrated computational element (“ICE”) configured to detect a characteristic of the cement additive. An output signal may then be generated corresponding to the characteristic of the cement additive detected by the ICE, which may be received and processed with a signal processor to yield a value for the characteristic of the cement additive. The value of the characteristic of the cement additive may then be used to determine an amount of the cement additive for use in producing a cement slurry.
