Abstract:
A system detects an analyte suspected of being present in a sample. The reader reads an optical tag on a substrate, which is configured to immobilize the tag on a substrate surface. The optical tag is bound to a probe and includes a plurality of pores that create an effective index of refraction. The plurality of pores and a thickness of the tag are selected for a reflectance property. The substrate is configured to contact a sample suspected of comprising an analyte. The probe is capable of binding specifically to the analyte. The reader is configured to expose the tag to light to generate a sample spectral signature that is a function of the effective index of refraction, the thickness of the optical tag, and whether the analyte is coupled to the probe. The sample spectral signature is compared to a reference to detect the analyte in the sample.
Abstract:
We describe a system for determining the condition of a tuber. The system comprises a light source to stimulate the tuber to promote chlorophyll production and/or sprouting. The light source may be configured to provide substantially continuous optical stimulation to the tuber. The system may further comprise an optical instrument to measure an optical response of the tuber, and a controller. The controller may control the optical instrument to make a time series of optical measurements on the tuber at intervals during the substantially continuous optical stimulation to determine a time evolution of an optical response of the tuber. Preferably the time series evolution is determined over a period of less than eight hours. The system may also include a data processor to analyse the time evolution of the optical response to determine a condition of the tuber.
Abstract:
An example embodiment may include a hyperspectral analyzation subassembly configured to obtain information for a sample. The hyperspectral analyzation subassembly may include one or more transmitters configured to generate electromagnetic radiation electromagnetically coupled to the sample, one or more sensors configured to detect electromagnetic radiation electromagnetically coupled to the sample, and an electromagnetically transmissive window. At least one of the sensors may be configured to detect electromagnetic radiation from the sample via the window. The hyperspectral analyzation subassembly may include an analyzation actuation subassembly configured to actuate at least a portion of the hyperspectral analyzation subassembly in one or more directions of movement with respect to the sample.
