Abstract: The present invention relates to a device for the discrimination of biological tissues, such that it is capable of carrying out the discrimination of tissue under complicated operating conditions, for example due to the presence of contaminating elements given off by a cutting operation, due to the presence of moisture in the biological tissue, or due to the presence of a non-controlled atmosphere that interferes with the results of the readings. The invention allows building more complex devices, including cutting instruments, such that it is possible to carry out a surgical intervention in a safe manner by preventing cutting into tissues that are to be avoided during said cutting operation.

Abstract: A diagnostic testing method for a detector of a spectrometer. The spectrometer comprises a source of line spectra configured to emit at least one branched pair of spectral lines from an excited species. The method comprises performing a plurality of detector diagnostic measurements and diagnosing a detector operating condition. Each detector diagnostic measurement comprises measuring an intensity of a first spectral line emitted by an excited species of the source of line spectra using the detector, and measuring an intensity of a second spectral line emitted by the excited species of the source of line spectra using the detector. The first and second spectral lines emitted by the excited species of the source of line spectra form a branched pair of spectral lines, and the spectrometer is controlled to vary the intensity of the first and second spectral lines incident on the detector for the plurality of detector diagnostic measurements.

Abstract: A gas measurement system as disclosed can include a coherent light source, which emits a light beam; a detector; a beam path formed between the light source) and the detector; and a gas cell arranged in the beam path such that the detector receives light transmitted through the gas cell. The gas cell can include a porous ceramic and have an optical path length which is a multiple of the actual layer thickness of the gas cell. A optical element can be arranged in the beam path between the light source and the gas cell with the light beam emitted by the light being widened and unfocussed as the light beam enters the gas cell.

Abstract: Systems and methods for determining one or more properties of a sample are disclosed. The systems and methods disclosed can be capable of measuring along multiple locations and can reimage and resolve multiple optical paths within the sample. The system can be configured with one-layer or two-layers of optics suitable for a compact system. The optics can be simplified to reduce the number and complexity of the coated optical surfaces, et al. on effects, manufacturing tolerance stack-up problems, and interference-based spectroscopic errors. The size, number, and placement of the optics can enable multiple simultaneous or non-simultaneous measurements at various locations across and within the sample. Moreover, the systems can be configured with an optical spacer window located between the sample and the optics, and methods to account for changes in optical paths due to inclusion of the optical spacer window are disclosed.
