    Abstract: An imaging system and method are provided that use imaging information relating to positions of one or more retroreflectors attached to one or more surfaces of an object of interest to determine the shape and/or displacement of the surface or surfaces on which the retroreflector or retroreflectors are located. A variety of types of information may then be ascertained based on the determination as to the shape and/or displacement of the surface of the object, such as the value of some physiological parameter of a patient, internal and external pressure of an object, acoustical vibrations sensed by a microphone, positions of fingertips on a keyboard, etc.

    Abstract: A water detecting apparatus includes a source of infra-red radiation which is reflected off an inner surface of a pipe wall onto a mirror directing the infra-red signal along a path to an infra-red detector connected by an electrical signal path to an electronic control. The path is interrupted by a rotating chopper having windows occupied by two optical filters. The first optical filter only passes an infra-red signal of wavelength 1900 nm which is absorbed by water, while the second optical filter only passes an infra-red signal of wavelength 2200 nm, another wavelength absorbed by water, but not to the same extent as the 1900 nm wavelength. The 2200 nm wavelength serves as a reference signal. When the strength of the infra-red signal path by the first optical filter decreases in relation to the strength of the infra-red reference signal path by the second optical filter, this is due to water on the surface absorbing the 1900 nm wavelength more than the 2200 nm wavelength, and the electronic control causes an indicator to indicate the presence of the water.

    Abstract: A conversion and kit for a dual beam spectrophotometer permitting it to operate in dual wavelength mode and thereby obtaining resolution heretofore unavailable from similar machines. The present invention provides for a second light source and directs it through the sample. By eliminating the reference path of the dual beam machine, the second light source permits the converted dual beam spectrophotometer to work in dual wavelength mode and thereby generate higher resolution while using the same instrument. The conversion allows the spectrophotometer to be operated in dual beam mode and for the easy/rapid changing between dual beam and dual wavelength modes.

    Abstract: An absorption photometer for measuring the absorption by conducting the light to a thin flow cell in which a liquid sample flows, wherein the sample light for measuring the absorption peak is superimposed on the reference light selected from the transparent (window) range of the liquid and the absorbance is detected by separating the sample light and reference light after transmission of the flow cell. Changes in the light path conditions can be monitored accurately, and therefore high-accuracy measurement immune to noises is made possible even using an elongated flow cell.

    Abstract: The two-beam photometer is suitable for extinction measurement on weakly-absorbent samples. The principle of measurement is based on a wavelength selection in either the comparison beam and the measuring beam. In the beam configuration measuring and comparison beam are coincident in space and follow each other periodically. The wavelength ranges in measuring beam and comparison beam is selected by a graded interference filter which is arranged perpendicular to the optical axis and rotatable about this axis. In the zone of the graded interference filter the path of the beam is formed by two narrowly limited beams symmetrically to the optical axis. Both beams are produced preferably by two light sources whose distance may be varied in a direction perpendicular to the optical axis while the symmetry with respect to the optical axis is maintained.
