Abstract: A wearable device for use with a smart phone or tablet includes LEDs for measuring physiological parameters by modulating the LEDs and generating a near-infrared multi-wavelength optical beam. At least one LED emits at a first wavelength having a first penetration depth and at least another LED emits at a second wavelength having a second penetration depth into tissue. The device includes lenses that deliver the optical beam to the tissue, which reflects the first and second wavelengths. A receiver is configured to capture light while the LEDs are off and while at least one of the LEDs is on and to difference corresponding signals to improve a signal-to-noise ratio of the optical beam reflected from the tissue. The signal-to-noise ratio is further increased by increasing light intensity of at least one of the LEDs. The device generates an output signal representing a non-invasive measurement on blood within the tissue.

Abstract: Non-invasive monitoring of blood constituents such as glucose, ketones, or hemoglobin A1c may be accomplished using near-infrared or short-wave infrared (SWIR) light sources through absorbance, diffuse reflection, or transmission spectroscopy. As an example, hydro-carbon related substances such as glucose or ketones have distinct spectral features in the SWIR between approximately 1500 and 2500 nm. An SWIR super-continuum laser based on laser diodes and fiber optics may be used as the light source for the non-invasive monitoring. Light may be transmitted or reflected through a tooth, since an intact tooth and its enamel and dentine may be nearly transparent in the SWIR. Blood constituents or analytes within the capillaries in the dental pulp may be detected. The non-invasive monitoring device may communicate with a device such as a smart phone or tablet, which may transmit a signal related to the measurement to the cloud with cloud-based value-added services.

Abstract translation: 通过吸收，漫反射或透射光谱可以使用近红外或短波红外（SWIR）光源实现对血液成分如葡萄糖，酮或血红蛋白A1c的非侵入性监测。 作为示例，水 - 碳相关物质如葡萄糖或酮在SWIR中在约1500和2500nm之间具有不同的光谱特征。 可以使用基于激光二极管和光纤的SWIR超连续激光器作为非侵入性监测的光源。 光可以通过牙齿传播或反射，因为完整的牙齿及其牙釉质和牙质在SWIR中可能几乎是透明的。 可以检测牙髓中毛细血管内的血液成分或分析物。 非侵入式监测设备可以与诸如智能电话或平板电脑的设备进行通信，智能电话或平板电脑可以使用基于云的增值业务将与测量相关的信号传输到云。

Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) sources such as lamps, thermal sources, LED's, laser diodes, super-luminescent laser diodes, and super-continuum light sources for early detection of dental caries measure transmission and/or reflectance. In the SWIR wavelength range, solid, intact teeth may have a low reflectance or high transmission with very few spectral features while a carious region exhibits more scattering, so the reflectance increases in amplitude. The spectral dependence of the transmitted or reflected light from the tooth may be used to detect and quantify the degree of caries. Instruments for applying SWIR light to one or more teeth may include a C-clamp design, a mouth guard design, or hand-held devices that may augment other dental tools. The measurement device may communicate with a smart phone or tablet, which may transmit a related signal to the cloud, where additional value-added services are performed.
