Abstract:
A spectroscopic rotating compensator material system investigation system including a photo array (DE's) for simultaneously detecting a multiplicity of wavelengths is disclosed. The spectroscopic rotating compensator material system investigation system is calibrated by a mathematical regression based technique involving, where desirable, parameterization of calibration parameters. Calibration is possible of calibration parameters. Calibration is possible utilizing a single two-dimensional data set obtained with the spectroscopic rotating compensator material system investigation system in a "material system present" or in a "straight-through" configuration.
Abstract:
A distributed sensor (10) includes a plurality of stages (24, 28, 32, 36, 40) connected in series, each stage incorporating a length of polarization maintaining fiber (12) exposed to a phenomena such as mechanical deformation or temperature to be sensed. Inter-mode couplers are provided between the sensing fibers (26, 30, 34, 38) of the various stages. The overall transfer function of the device at a plurality of wavelengths is deconvoluted to determine the birefringence of each sensing region and does monitor plural phenomena independently of one another.
Abstract:
Methods and apparatus for screening diverse arrays of materials using infrared imaging techniques are provided. Typically, each of the individual materials on the array will be screened or interrogated for the same material characteristic. Once screened, the individual materials may be ranked or otherwise compared relative to each other with respect to the material characteristic under investigation. According to one aspect, infrared imaging techniques are used to identify the active sites within an array of compounds by monitoring the temperature change resulting from a reaction. This same technique can also be used to quantify the stability of each new material within an array of compounds. According to another aspect, identification and characterization of condensed phase products is achieved, wherein library elements are activated by a heat source serially, or in parallel. According to another aspect, a Fourier transform infrared spectrometer is used to rapidly characterize a large number of chemical reactions contained within a combinatorial library.
Abstract:
A 6-axis laser measurement system (300) includes a novel 5-D measurement apparatus and precision laser roll detector system (100). The 5-D system (105) measures pitch, yaw, X, Y, Z displacements with a single setup of a laser head (102) and detection housing (302). The laser roll detector (100) uses a polarizing prism (104) such as a Glan-Thompson prism, and at least two photodetectors (D1, D2, D3, D4). A linearly polarized laser beam enters the prism (104), and the beam is split into two polarized components, the intensities of which vary with roll orientation of the detector (105) relative to the polarized laser beam. The outputs of the two detectors (D1, D2) are connected to the positive and negative inputs, respectively, of a high gain differential amplifier (108) which provides roll output.
Abstract:
An apparatus for urinalysis which requires easy maintenance without using articles of consumption by measuring the optical rotation of urine to determine the concentration of optically active substances in the urine. Polarized light is transmitted through a sample placed in a magnetic field, and a polarimeter detects the change in the direction of polarization of light caused by the effect of the magnetic field. Thus, there are provided a small-sized low-cost reliable apparatus for urinalysis.
