摘要： An optical measurement device includes a light source, a first detector, and a second detector. The light source emits light to a measurement site of a patient and one or more detectors detect the light from the light source. At least a portion of a detector is translucent and the light passes through the translucent portion prior to reaching the measurement site. A detector receives the light after attenuation and/or reflection or refraction by the measurement site. A processor determines a light intensity of the light source, a light intensity through a tissue site, or a light intensity of reflected or refracted light based on light detected by the one or more detectors. The processor can estimate a concentration of an analyte at the measurement site or an absorption or reflection at the measurement site.

摘要： According to the present disclosure, there is provided a technique capable of suppressing an erroneous detection of a presence or absence of a substrate caused by a light receiver receiving a specularly reflected light. There is provided a technique that includes: a holding structure provided with a placing surface capable of accommodating a substrate thereon; a light detector including: a light emitter arranged to irradiate an irradiation light toward a back surface of the substrate placed on the placing surface; and a light receiver arranged to be capable of receiving a diffusely reflected light of the irradiation light irradiated from the light emitter without receiving a specularly reflected light of the irradiation light; and a controller configured to be capable of determining a presence or absence of the substrate based on a light receiving state of the light receiver.

摘要： Disclosed is a method for performing a measurement of an exposed pattern in photoresist on a substrate and an associated metrology device. The method comprises imparting a beam of measurement radiation on said exposed pattern over a measurement area of a size which prevents or mitigates photoresist damage from the measurement radiation; capturing scattered radiation comprising said measurement radiation subsequent to it having been scattered from said exposed pattern and detecting the scattered radiation on at least one detector. A value for a parameter of interest is determined from the scattered radiation.

摘要： A waveguide sensor system is provided. The system includes a light source and a waveguide formed from a light transmitting material. Light from the light source enters the waveguide at an input area and travels within the waveguide by total internal reflection to an analyte area and light to be analyzed travels within the waveguide from the analyte area by total internal reflection to an output area. An optical sensor is coupled to the output area and is configured to interact with the light to be analyzed. The system includes a plurality of pores located along the outer surface within the analyte area and formed in the light transmitting material of the waveguide, and the pores are configured to enhance light interaction with the analyte within the analyte area. The pores and analyte area may be protected and/or enhanced with a hydrophobic layer overlaying the pores.
