Abstract: A phase refractive index of a test object is measured with high accuracy. A phase difference between a reference light beam and a test light beam is measured by dividing light from a light source into the reference light beam and the test light beam, and causing interference between the test light beam transmitted through the test object and the reference light beam. A phase refractive index of the test object is calculated by calculating a value corresponding to an integral multiple of 2π included in the phase difference, based on a slope of a phase refractive index of a reference object with respect to wavelength.

Abstract: The present invention is thus directed to an automated system and method of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Such a methodology and system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

Abstract: The invention relates to systems and methods for improving optical detection and sensitivity in situations in which emission of luminescent light is monitored. It is provided a sample carrier which achieves increased sensitivity of luminescent light detection. The sample carrier comprises a sample carrying part and a light reflecting part; wherein the light reflecting part is positioned to allow an optical collection and detection system to collect not only luminescent light emitted from the sample positioned on the sample carrying part in a direction of the optical collection and detection system, but also luminescent light emitted from the sample in a direction away from the optical collection and detection system and reflected in the direction of the optical collection and detection system via the light reflecting part. When an excitation light source is needed, the light reflecting part also allows the excitation light rays passing through the sample to hit the light reflecting part, and reflect back in the opposite direction thus the reflected excitation light also passes through the sample. Also provided are methods of using such a sample carrier.

Abstract: Methods and apparatus for detecting biological activity within a sample are disclosed. The present invention provides a combination of a first and a second infrared light source arranged on the side of a sample vial, and a first and a second narrow-band infrared detector similarly arranged on the side of the vial approximately opposite the sources. The disclosed arrangement cancels the sources of error while measuring the carbon dioxide content of the headspace gas above the sample. In operation, the present invention sequentially measures the photocurrents generated at each detector with no source turned on, with the first source turned on, and with the second source turned on and the first source turned off. The CO.sub.2 absorption coefficient of the vial headspace gas is then calculated based on the photocurrents measured. This present invention allows compensation for source aging, detector aging, and vial wall thickness changes. Moreover, the present invention permits a determination of the absolute absorption coefficient at a selected wavelength, most preferably about 4.26 .mu.m, which is the CO.sub.2 absorption characteristic wavelength. The determination of the absolute CO.sub.2 concentration within the headspace permits the detection of bacterial growth processes. Additionally, the disclosed source/detector combination can be produced at low cost. Thus, in preferred embodiments, the apparatus of the present invention comprises a plurality of vials that are simultaneously monitored by providing each of the plurality of vials with its own source/detector combination and activating and deactivating the sources and detectors using a multiplexer/demultiplexer arrangement.
