Abstract: A method for correcting frequency offset in a dual comb spectroscopy system is provided. The method includes causing a first laser (L1) generator to transmit L1 pulses at a repetition rate of a first frequency and causing a second laser (L2) generator to transmit L2 pulses at a repetition rate of a second frequency. The method also includes interrogating a reference material using a combination of the L1 pulses and the L2 pulses and capturing reference cell pulses. The method further includes interrogating a material of interest using the L1 pulses and capturing material of interest pulses. The method includes determining a frequency jitter based on the captured reference cell pulses and the combination of the captured material of interest pulses and the L2 pulses.

Abstract: Optical imaging or spectroscopy described can use laminar optical tomography (LOT), diffuse correlation spectroscopy (DCS), or the like. An incident beam is scanned across a target. An orthogonal or oblique optical response can be obtained, such as concurrently at different distances from the incident beam. The optical response from multiple incident wavelengths can be concurrently obtained by dispersing the response wavelengths in a direction orthogonal to the response distances from the incident beam. Temporal correlation can be measured, from which flow and other parameters can be computed. An optical conduit can enable endoscopic or laparoscopic imaging or spectroscopy of internal target locations. An articulating arm can communicate the light for performing the LOT, DCS, or the like. The imaging can find use for skin cancer diagnosis, such as distinguishing lentigo maligna (LM) from lentigo maligna melanoma (LMM).

Abstract: The present disclosure relates to agriculture. The teachings thereof may be embodied in methods to determine a percentage of weeds and/or control device. For example, a method for determining a weed percentage in an observation section of a field may include: acquiring actual spectral information using an optical observation section sensor aimed at the observation section; acquiring reference spectral information using an optical reference sensor aimed at a reference section of the same ground area; determining a difference between the actual spectral information and the reference spectral information; and mapping the difference to the weed percentage using predefined mapping.

Abstract: According to one embodiment, a value of a film thickness of a processing object disposed above a substrate is obtained. Then, a wavelength that provides a highest degree of intensity of signal light reflected when the signal light is incident onto the processing object having the value of the film thickness, based on wavelength selection reference information is selected. Then, a first instruction performing an alignment process to the substrate by use of signal light having a wavelength thus selected is generated. The wavelength selection reference information is information that includes a correlation between values of the film thickness of the processing object and degrees of intensity of the signal light, with respect to a plurality of wavelengths.

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.

Abstract: An optical analysis system and process are disclosed. The optical analysis system includes one or more optical filter mechanisms disposed to receive light from a light source and a detector mechanism configured for operative communication with the one or more optical filter mechanisms, the operative communication permitting measurement of properties of filtered light, filtered by the one or more optical filter mechanisms followed by optical filtering by the mosaic optical filter mechanism from the light received. The one or more optical filter mechanisms are configured so that the magnitude of the properties measured by the detector mechanism is proportional to information carried by the filtered light. The process uses the optical analysis system.
