摘要： The invention relates to a method of imaging an interior of a turbid medium (45) comprising the following steps: accommodation of the turbid medium (45) inside a receiving volume (20); coupling transmission input light (65) from a transmission light source into the receiving volume (12), with said transmission input light (65) being chosen such that it is capable of propagating through the turbid medium (45) and with at least a part of said transmission input light (65) passing through a matching medium (50) in the receiving volume (12), said matching medium (50) being chosen to reduce optical boundary effects at an interface between the turbid medium (45) and its surroundings; detection of transmission output light emanating from the receiving volume as a result of coupling transmission input light (65) from the transmission light source into the receiving volume (12) through use of a transmission photodetector unit. The invention also relates to a system for imaging an interior of a turbid medium (45) and a medical image acquisition system both using the method. According to the invention, the method, system for imaging an interior of a turbid medium (45), and medical image acquisition system are adapted such that data relating to the exterior of the turbid medium (45) can be obtained. This object is realized in that the method further comprises the following additional steps: coupling geometry input light (70, 75, 80) from a geometry light source into the receiving volume (12), with the receiving volume comprising the turbid medium (45), with the receiving volume (12) further comprising a geometry medium (60) for surrounding the turbid medium (45) during coupling of geometry input light (70, 75, 80) into the receiving volume (12), and with the combination of the geometry input light (70, 75, 80), the geometry medium (60), and the interface being chosen for creating a contrast between the turbid medium and its surroundings; —detection of the contrast between the turbid medium (45) and its surroundings; reconstructing an image of an interior of the turbid medium (45) using the detected contrast.

摘要： A beam splitter array includes first and second beam splitters and a reflector to reflect part of a beam from the second splitter. The first splitter outputs a first beam having a power spectral density comprising a substantial portion of a white light spectrum from a first output port, and a second beam of optical radiation having a power spectral density comprising a substantial portion of a first non-white spectrum and a substantial portion of a second non-white spectrum from a second output port, from an input beam received at a first angle of incidence. The second splitter receives the second beam at a second incidence angle, and reflects a substantial portion of the second beam having a power spectral density comprising the first non-white light spectrum, and transmits a substantial portion of the second beam having a power spectral density comprising the second non-white light spectrum.

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.

摘要： A method for determining the degree of sensitivity of a strain of fungus to an antifungal agent by using the possible change in a chitin level in a population of cells of a strain of fungus to an antifungal agent. The change is determined compared to the chitin level of a population of cells of said strain of fungus in the absence of antifungal agent.
