Abstract: The wide-angle emission filter includes a base matrix, a photoresist, and a colorant. The base matrix has a flat shape and including a transparent material. The base matrix does not generate fluorescent light or phosphorescent light by an excitation light. The photoresist is disposed in the base matrix. The photoresist is fixed in a solid state through at least one method selected from the group consisting of thermal hardening, photo hardening, and drying. The colorant is disposed in the base matrix and includes light having a predetermined wavelength range. The wide-angle emission filter filters the excitation light regardless of an incident angle of the excitation light.

Abstract: Mechanisms for identifying energy received from a scene are provided. A coded aperture in an optical system receives energy from a scene. The coded aperture comprises a plurality of wavelength filter sets arranged in a predetermined pattern. Each wavelength filter set is configured to transmit energy in a corresponding wavelength band of a plurality of different wavelength bands. The coded aperture transmits the energy toward a detector array comprising a plurality of detector elements. The detector array generates sensor data that quantifies energy received by each detector element. The sensor data is processed based on the predetermined pattern to identify spatial locations of energy in each corresponding wavelength band with respect to the scene.

Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract: A method for determining a chance to enable a zeroing of gas analysis is disclosed herein. The method includes emitting radiation, and receiving emitted radiation, the received radiation comprising a first wavelength range absorbed by the at least one desired gas component and one or more disturbing factor, and a second wavelength range absorbed by the disturbing factor, the first wavelength range differing from the second wavelength range. The method also includes providing to a processing unit a first signal data indicative of a concentration of the at least one desired gas component and absorption of the disturbing factor, and a second signal data indicative of absorption of the disturbing factor. The method also includes determining a stability of the first and second signal data as a function of time, and if they are substantially stable enabling the zeroing to improve a measurement accuracy.

Abstract: A method for measuring the concentration of a gas component in a measuring gas. An absorption line of the gas component is varied as a function of the wavelength of the light of a wavelength-tunable light source within a periodically sequential scanning interval. The absorption line of the gas component is modulated with a frequency (f0). Modulated light is guided through the measuring gas onto a detector. A measurement signal generated by the detector is demodulated upon determining a harmonic (nf0) of the frequency (f0). A measurement result is produced by fitting a setpoint curve to the profile of the demodulated measurement signal. Both demodulated measurement signal and setpoint cure are filtered with the aid of the same filter function. The filter function is operative to suppress noise signal components of the demodulated measurement signal that disturb both signal components of the demodulated measurement signal and the setpoint curve.
