摘要： Single or multi-cell reservoir sensors with single illumination sources and one or more detectors per cell unit have an arrangement whereby a gaseous, vapor or liquid sample enters the cell body and interacts with a sensing solution to detect and quantify a given species. Entrance of the sample into the sensor is through an opening in the cell body which may be covered with a membrane to contain the sensing reagent and to presort the species entering the cell. Reservoir cells can be used with organic, inorganic or biochemical sensing materials. A variety of sensors as alcohol, drugs of abuse, organic halides, cyanide and inorganic ions are provided.

摘要： A species-specific metal clad segment on a waveguide, including a planar waveguide, allows controlled light leakage of light propagating through the waveguide by total internal reflection, to measure refractive index and identify chemical species. A waveguide sensor is designed for a particular chemical species by selecting a metal clad with an affinity for the species and by matching the refractive indices of the waveguide body, clad, metal clad segment and chemical species. Dual or multiple measurement methods use a pair or multiple metal clad segments of different specificity. The metal clad segment may include another material to provide a suitable refractive index while having the desired affinity for the chemical species or to provide a catalyst to react the species to form a reaction product which is more readily detected.

摘要： A fiber optic sensing device for measuring a chemical or physiological parameter of a body fluid or tissue is provided. To one end of the fiber is attached a polymer including a plurality of photoactive moieties selected from the group consisting of chromophores and lumophores, the photoactive moieties spaced apart so as to minimize chemical or physical interaction therebetween while optimizing the density of photoactive moieties. In one embodiment, a polymer chain is covalently bound to photoactive moieties through functional groups such as esters, amides, or the like. In a second embodiment, a polymer chain is inherently fluorescent and is formed from at least one monomeric unit. These devices are particularly useful as pH and oxygen sensors.

摘要： Simplicity, sensitivity and versatility of optical sensors based on competitive immunoassays using antibody-antigen reactions are achieved by solid-state, single-step reactions which permit accurate sensitive qualitative and quantitative information to be obtained without human participation. All of the chemistry-biochemistry is an inherent part of the sensor. A direct reaction occurs when the sample (antigen) is brought in contact with the sensor. The sensitivity of the competitive immunoassay optical sensor is controlled and increased by selecting a tag for the antigen or altering the attachment of a tag to an antigen so that the binding of tagged antigen to an antibody is decreased relative to the binding of untagged antigen to the antibody. The user can vary size, molecular weight and geometric configuration of the tagged antigen. This can be accomplished by selecting the proper tag or by attaching the indicator material to the antigen through a spacer or by attaching the tag directly to the antigen and attaching a compound of proper molecular weight and size elsewhere. Pretreatment of the substrate to which the antibody-bound tagged antigen is immobilized to block the surface from unwanted interferences and the use of optical isolation increases sensitivity. If the tag cannot be attached to the antigen, it is attached to the antibody. Attaching the controlled size, molecular weight tag to either the antigen or antibody permits the analysis of species not normally measureable by competitive immunoassay, thus increasing the versatility of the method.

摘要： An ice sensor for the remote rapid indication of ice formation or the presence of ice is a fiber optic "switch", activated by ice but not by water, and based on the difference in optical properties between water and ice. The approach is to construct a "fiber optic" which itself is the ice sensor. The fiber optic sensor (FOS) is designed so that no light is transmitted when water is present but as soon as ice begins to form, light is relayed. Thus ice switches on the light- In addition, limited quantitative information can be made available on the rate of ice formation. Alternatively the sensor can be formed of another type optical waveguide instead of an optical fiber. The ice sensor is formed by placing spaced stripes of a clad material on a fiber optic core, or other waveguide structure, where the clad has a refractive index close to ice and the core has an index greater than the clad but less than water. It is best to index match the core to the clad for optimal transmission when ice forms in the gaps between the clad stripes. The advantages of the ice sensor include: specific, sensitive, real-time response, small, light weight, inexpensive, requires no line-of-sight, EMI immune, rugged and flexible. The instrumentation needed to operate the ice FOS is simple, small, light weight, inexpensive, easy to operate, battery powered - optional, rugged, reliable and amenable to telemetry of information.
