Abstract: The invention comprises a method and apparatus for selecting optical pathways sampling a common tissue position, such as a lateral mean range in the dermis, of a person for analysis in a noninvasive analyte property determination system, comprising the steps of: probing skin with a range of illumination zone-to-detection zone distances with at least two wavelength ranges, which optionally overlap, and selecting, using a metric, illumination zone-to-detection zone distances having mean optical pathways probing the common tissue layer, such as without the mean optical pathways entering the subcutaneous fat layer of the person. Optionally, the skin tissue layers are modulated and/or treated via tissue displacement before and/or during data collection.

Abstract: An approach for controlling light exposure of a light sensitive object is described. Aspects of this approach involve using a first set of radiation sources to irradiate the object with visible radiation and infrared radiation. A second set of radiation sources spot irradiate the object in a set of locations with a target ultraviolet radiation having a range of wavelengths. Radiation sensors detect radiation reflected from the object and environment condition sensors detect conditions of the environment in which the object is located during irradiation. A controller controls irradiation of the light sensitive object by the first and second set of radiation sources according to predetermined optimal irradiation settings specified for various environmental conditions. In addition, the controller adjusts irradiation settings of the first and second set of radiation sources as a function of measurements obtained by the various sensors.

Abstract: Surface sensing methods for imaging a scanned surface of a sample via sum-frequency vibrational spectroscopy are disclosed herein. The methods include exposing a sampled location of the scanned surface to a visible light beam and exposing the sampled location to a tunable infrared beam such that the tunable infrared beam is at least partially coincident with the visible light beam. The methods also include varying a frequency of the tunable infrared beam an inducing optical resonance within an imaged structure that extends at least partially within the sampled location. The methods further include receiving at least a portion of an emitted light beam from the sampled location and scanning the visible light beam and the runnable infrared beam across the scanned portion of the scanned surface. The methods also include generating an image of the scanned portion of the scanned surface based upon the receiving and the scanning.

Abstract: A dual-comb spectrometer comprising two lasers outputting respective frequency combs having a frequency offset between their intermode beat frequencies. One laser acts as a master and the other as a follower. Although the master laser is driven nominally with a DC drive signal, the current on its drive input line nevertheless oscillates with an AC component that follows the beating of the intermode comb lines lasing in the driven master laser. This effect is exploited by tapping off this AC component and mixing it with a reference frequency to provide the required frequency offset, the mixed signal then being supplied to the follower laser as the AC component of its drive signal. The respective frequency combs in the optical domain are thus phase-locked relative to each other in one degree of freedom, so that the electrical signals obtained by multi-heterodyning the two optical signals are frequency stabilized.

Abstract: A system and method for analyzing a sample using Raman spectral light includes a light source, a light detector, a narrow band pass filter and an analyzer. Within the system, excitation light is directed to interrogate the sample. The narrow band pass filter is positioned to receive Raman scattered light produced as a result of the interrogation. The light detector is positioned to receive the Raman scattered light that has passed through the at least one narrow band pass filter. The analyzer contains stored instructions that when executed cause the processor to a) control the light source; and b) process signals produced by the light detector to analyze the sample material, the signals representative of the intensity of the Raman scattered light received by the at least one light detector corresponding to one or more wavenumbers in a high wavenumber region of a Raman signal.
