An analysis tool that use ultraviolet wavelengths of oil fluorescence to analyze drill cuttings. An oil fluorescence tool includes an ultraviolet light source which directs ultraviolet light toward drilled cuttings. The interaction of the light and cuttings results in fluorescence emanating from the oil. These wavelengths are recognized by a camera which generates an image showing the intensity of the fluorescence. A computer having image recognition software is coupled to the camera in order to interpret and display the intensity and range of the fluorescence in the image.

Provided is a terahertz wave spectrometry system that is capable of easily identifying and quantitating an analyzing target molecule in an analyte, even if the analyte contains water, by calculating a baseline function expressing the absorption characteristic of water peculiar to the terahertz wave.

In some instances, an apparatus can include a light sensitive imaging sensor having a surface to receive a fluid sample, a body to be moved relative to the light sensitive imaging sensor and having a surface to touch a portion of the fluid sample, and a carrier to move the body toward the surface of the light sensitive imaging sensor to cause the surface of the body to touch the portion of the fluid sample, so that as the surface of the body touches the portion of the fluid, the surface of the body (i) is parallel to the surface of the light sensitive imaging sensor, and (ii) settles on top of the fluid sample independently of motion of the carrier.

Provided is a foodstuff analysis device capable of readily calculating calories or component weights. The foodstuff analysis device has a light-emitting unit, a light-receiving section, and a control unit. The light-emitting unit irradiates light including at least some wavelengths among wavelengths in the range 700-1,100 nm, on to an analysis target. The light-receiving section receives light reflected from the analysis target. The control unit calculates the absorbance of light received by the light-receiving section, and calculates the calories of the analysis target on the basis of the calculated absorbance and on the basis of the correlation between absorbance and calories.

In some embodiments, a system for detecting the presence of a contaminant on a surface includes an infrared light source configured to shine infrared light on the surface, an infrared light detector configured to detect infrared light reflected from the surface, and a computing device configured to receive an infrared reflectance signal from the infrared light detector and detect the presence of the contaminant from a feature in the reflectance signal.

Methods and systems for measuring process induced errors in a multiple patterning semiconductor fabrication process based on measurements of a specimen and process information from one or more previous process steps employed to fabricate the specimen are presented herein. A metrology tool is employed after a number of process steps have been executed. The metrology tool measures structural parameters of interest of metrology targets on the wafer based on measured signals and process information, and communicates correctable process parameter values to one or more process tools involved in the previous process steps. When executed by the appropriate process tool, the correctable process parameter values reduce process induced errors in the geometry of the structures fabricated by the process flow. In another aspect, multiple metrology tools are used to control a fabrication process in combination with process information from one or more process steps in the process flow.
