Abstract: Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.

Abstract: A method of making a colorimeter colour standard, including determining print parameters required to achieve a desired colour for the colour standard, printing the desired colour on a colour-receiving face of a first transparent piece using the determined print parameters and permanently affixing the printed first piece to a second transparent piece such that the colour-receiving face of the first transparent piece and a joining face of the second transparent piece are positioned at the interface between the first transparent piece and the second transparent piece.

Abstract: An illumination device for a spectral optical measurement device includes arranged with respect to an optical axis of the illumination device which, during a measurement operation, extends along a normal to a center point of an area of a sample to be illuminated. One or more segments of a mirror in a shape of a ring are centered on the optical axis. The mirror has an internal reflective surface arranged such that, during the measurement operation, the internal reflective surface receives light emitted from the light source and reflects the light over the area of the sample to be illuminated. The internal reflective surface has a freeform shape in a cross-section through the internal reflective surface in a plane parallel to the optical axis (for example in which the optical axis lies), and, in a cross-section of the mirror in a plane perpendicular to the optical axis, the internal reflective surface is represented by a straight line.

Abstract: Aspects relate to mechanisms for increasing the field of view of a spectrometer. An optical device may be configured to simultaneously couple light from different locations (spots) on a sample to the spectrometer to effectively increase the spectrometer field of view. The optical device can include a beam combiner and at least one reflector to reflect light beams from respective spots on the sample towards the beam combiner. The beam combiner can combine the received light beams from the different spots to produce a combined light beam that may be input to the spectrometer.

Abstract: A CubeSat compatible spectrometer including a slit having a first length and first width; a diffraction grating; and a two dimensional focal plane array electromagnetically coupled to the diffraction grating. The 2D focal plane array includes an array of pixels including a plurality of sets of pixels. Diffraction of electromagnetic radiation transmitted through the slit by the diffraction grating forms a plurality of beams, each of the beams comprising a different one of the bands of the wavelengths in the electromagnetic radiation, and each of the beams transmitted onto a different one of the sets of the pixels.

Abstract: A divided-aperture infrared spectral imaging (DAISI) system that is structured to provide identification of target chemical content in a single imaging shot based on spectrally-multiplexed operation. The system is devoid of spectral scanning acquisition of infrared (IR) spectral signatures of target content with an IR detector and does not require content.

Abstract: A measurement system for measuring blood characteristics includes a controller, an emitter, a sensor, and a reference sensor. The emitter emits light at a plurality of wavelengths from a first side of a blood flow channel to a second side of the blood flow channel. The sensor is provided on the second side of the blood flow channel. The reference sensor is provided on the first side of the blood flow channel. The controller compensates measurements from the sensor based upon measurements from the reference sensor. The reference sensor may be disposed in a position to increase noise immunity of the measurement system. The measurement system may be connected to or part of a dialysis system.
