Abstract: A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).

Abstract: A spectrometer system may be used to determine one or more spectra of an object, and the one or more spectra may be associated with one or more attributes of the object that are relevant to the user. While the spectrometer system can take many forms, in many instances the system comprises a spectrometer and a processing device in communication with the spectrometer and with a remote server, wherein the spectrometer is physically integrated with an apparatus. The apparatus may have a function different than that of the spectrometer, such as a consumer appliance or device.

Abstract: Imaging spectrometers can be used to generate hyperspectral images for medical diagnoses, contaminant detection, and food safety inspections, among other applications. An exemplary imaging spectrometer includes an integrated position sensing array that measures the relative positions of the interferometer components based on an interference pattern generated by illuminating the interferometer with a reference beam. Such an imaging spectrometer includes a processor that controls the interferometer component position by actuating a voice coil and several piezo-electric elements to align the components with respect to each other and to provide a desired optical path length mismatch between the interferometer arms. In some cases, the processor may use feedback and feed forward control, possibly based on the actuators' transfer functions, for more precise positioning. The processor may also implement adaptive and recursive spectral sampling to reduce the image acquisition period.
