Abstract: An arrangement for building a compact Fourier transform interferometer for optical radiation according to the Michelson principle or a principle derived therefrom. According to the invention, this arrangement is characterized in that the optical modulation of the radiation in at least one of the interferometer arms is produced by the translational displacement of micromechanical translation mirrors that are optically accessible on one side or on both sides, with an effective oscillation amplitude of at least 50 μm and a usable mirror surface area of at least 1 mm2. In doing so, the micromechanical mirror components according to the invention assume the function of known movable mirrors so that by using an almost massless microcomponent in comparison to conventional systems, a much smaller size and a mirror modulation frequency that is several orders of magnitude higher can be achieved. The arrangement according to the invention is used especially for optical spectroscopy.

Abstract: An interferometer structure is disclosed which has an integrated central mirror unit, which constitutes an integrated alignment unit permitting complete prealignment before the unit is incorporated into the interferometer. The integrated unit carries the beamsplitter and two folding mirrors. Alignment is accomplished by adjusting the positions of the two folding mirrors around vertical and horizontal axes. Both the stationary mirror and the movable mirror, which control the radiation path lengths in the two interferometer arms, are retroreflectors. Because of the folding miirror effect, resolution of the interferometer spectrometer system is significantly enhanced.

Abstract: This document describes techniques and devices for blood-solute calculation with a mobile device using non-invasive spectroscopy. A mobile device (502) includes a light source (504) that emits light toward an interferometer (508) that uses mirrors to separate and recombine the light. The interferometer directs the recombined light toward a person. Light reflected from, or transmitted through, the person is received through a reception port (506) to a photodetector (510) that outputs photodetector data that corresponds to a measured light intensity of the reflected and transmitted light as a function of a path length of the light or a mirror position of the interferometer. Based on the photodetector data, an interferogram is generated. Applying a technique such as a Fourier transform to the interferogram, a spectrum data set of the reflected and transmitted light is generated. Based on the spectrum data set, a concentration of solutes in the person's blood is calculated.
