Abstract: An optical environment oscillation detection system and an optical measurement method using the same are provided. This system includes a laser light source, a polarizer, a liquid crystal (LC) element, an analyzer, and an optical sensor arranged in sequence. A polarization axis of the polarizer and that of the analyzer are respectively parallel to a first and a second axis direction being perpendicular to each other. When there is no environmental disturbance, the alignment of LC cells in the LC element has an original pretilt angle, and the optical sensor senses a first scattered light intensity of the laser beam outputted from the analyzer. When there is environmental disturbance, the alignment of the LC cells has a changed pretilt angle in relative to the original pretilt angle, and the optical sensor senses a second scattered light intensity of the laser beam outputted from the analyzer.

Abstract: An optical measurement instrument is an integrated instrument that includes an optical cavity with a light source, a sample cuvette, and an optical sensor. The light source and sensor are on a bench that is on a translational or rotational mechanical platform such that optical beam can be moved to multiple sample containers. Each sample containers holds a distinct microorganism-attracting substance and a portion of a fluid sample containing an unknown microorganism. Each distinct microorganism-attracting substance is configured to bind with a single type of microorganism. The unknown microorganism in the fluid sample binds with the distinct microorganism-attracting substance in a single sample container. The instrument incubates the microorganism in the single sample container and detects the presence of the microorganism in the single sample container to thereby simultaneously identify the unknown microorganism.

Abstract: A method and an apparatus are presented for monitoring a concentration of a specific halogen in a body of water such as a spa or bathing unit for example. The apparatus comprises a housing in which is positioned an optical absorption analyzer for making first and second measurement of transmission of ultraviolet light from a light source emitting light at a specific wavelength. The second and first measurements are taken respectively before and after the ultraviolet light has travelled through a sample of water and are used to derive a concentration of the specific halogen. The derived concentration may then be communicated to a user using a display device and/or may be used to control operational components of a bathing unit for adjusting the concentration of halogen in the water. In some practical implementations, the apparatus may be embodied as a standalone device, which may be configured to float on the water of the bathing unit or, alternatively, may be configured for being installed in-line in a water circulation path of the bathing input by connecting the housing to circulation piping.

Abstract: An instrument determines a concentration of bacteria in a plurality of fluid samples, and comprises a housing, a rotatable platform, a plurality of fluid containers, a light source, a sensor, and a motor. The rotatable platform is within the housing. The fluid containers are located on the rotatable platform. Each fluid container holds a corresponding one of the plurality of fluid samples, and has an input window and an output window. The light source provides an input beam for transmission into the input windows of the fluid containers and through the corresponding fluid samples. The input beam creates a forward-scatter signal associated with the concentration of bacteria. The motor rotates the rotatable platform so that the input beam sequentially passes through each fluid sample. A sensor within the housing detects the forward-scatter signal exiting from the output window associated with the fluid sample receiving the input beam.
