摘要： A postacquired spectrophotometer, for use with a sample and reference. The spectrophotometer has a filter unit, defining an axis of movement, and pluralities of designated sites and dark sites disposed in uniform relation to the axis. The designated and dark sites are disposed in alternation. Alternating designated sites have apertures and filters covering the apertures. Further, a main member, coaxial with the filter unit, has sample and reference beam paths, which are intersected by the sites. The main member has disposed, in operative relation to the actuators, an actuator sensor, which generates an integration actuator signal upon alignment with each integration actuator and a clamping actuator signal upon alignment with each clamping actuator. Moreover, a drive continuously moves the filter unit relative to the axis and beam paths. Further, a light distribution system directs light separately from the sample and reference to respective beam paths, and then to a detector, which produces a detector signal responsive to light received. Finally, means for processing the signals is provided, including a clamping circuit, integrators, and a demultiplexer.

摘要： A spectrophotometer is described, comprising a single light source, a single detector, optics for dually and alternatively reading a sample and a reference, and only one moving part. That moving part is a chopper containing multiple pass-through apertures, each filled with a unique bandpass filter to select wavelengths to specifically illuminate the sample or reference. To inform the spectrophotometer whether and when it is reading the sample or the reference, trigger means are provided in at least twice the number of the pass-through apertures.

摘要： A waveguide optical device having a guide member for propagation of light in a longitudinal direction. The guide member has upper and lower boundaries. A mass of birefringent material is disposed proximal to the guide member. The birefringent material has molecular dipoles subject to alignment by an imposed electrical field. The birefringent mass is overlapped by the optical field of the propagated light. An upper electrode is disposed in spaced relation to the birefringent mass. A lower electrode is disposed in spaced relation to the guide member. The electrodes have the capability of imposing an alternating current voltage across the birefringent mass to rotate the molecular dipoles of the birefringent mass in a plane defined by the normal to the guide member and the propagation vector of the light. The boundaries and the electrodes define an upper isolation zone between the upper electrode and the upper boundary, a guide path between the boundaries, and a lower isolation zone between the lower boundary and the lower electrode. The guide path has an effective index of refraction greater than the effective indexes of refraction of the isolation zones.

摘要： There are disclosed an instrument and method for using near IR to discriminate between healthy and diseased tissue, using, e.g., a catheter and a spectrophotometer. Near IR is passed at certain wavelengths to suspected tissue, and reflected light is analyzed to determine the absorbance, and preferably the second derivative thereof. From identification of the absorption spectra of known diseased and known healthy tissue, a relation has been established to determine the following correlation equation for determining the predictive value of y:y=Co+C.sub.1 A(.lambda..sub.1)+C.sub.2 A(.lambda..sub.2)wherein A(.lambda..sub.1)+A(.lambda..sub.2) are the second derivatives for the absorbance at the two selected wavelengths. For blood cholesterol esters and plaque, .lambda..sub.1 is preferably 1714.5 and .lambda..sub.2 is preferably 1678.5 nm. Solving for the coefficients Co, C.sub.1 and C.sub.2, it has been shown that values of y less than -8.0 represent diseased tissue, which should be treated. Ablation laser treatment is described as one mode of treatment.
