    Abstract: Self-cleaning sensor window devices for mine site equipment and associated systems and methods are disclosed herein. In some embodiments, a self-cleaning sensor system includes a sensor housing having an opening, a sensor carried by the sensor housing, a self-cleaning window device coupled to the sensor enclosure and positioned at least partially within the opening. The self-cleaning window device comprises a window positioned forward of the sensor to allow the sensor to transmit and/or receive signals through the window, a cleaning assembly directed toward the window and configured to clean debris from the front surface of the window, and a controller operably coupled to the cleaning assembly. The controller can transmit control signals to the cleaning assembly to initiate cleaning of the front surface of the window.

    Abstract: In one embodiment, a method of constructing a corrective phase mask for an optical element, includes propagating, for each of one or more wavelengths, a point source field from an object plane to a corrective mask plane to determine a source field and propagating, for each of the one or more wavelengths, the point source field from an image plane to the corrective mask plane to determine an image field. The method may further include determining, for each of the one or more wavelengths, a phase modulation field based on the source field and the image field; and determining a multi-wavelength phase modulation field based on combining the phase modulation field for each of the one or more wavelengths.

    Abstract: A spectrometer for detecting an electromagnetic (EM) wave spectrum having one or more wavelength components within a spectral band of interest, a method of detecting an electromagnetic (EM) wave spectrum having one or more wavelength components within a spectral band of interest, and a method of constructing the spectrometer. The method comprises the steps of creating dispersed images of an entrance aperture on a plane of an exit aperture, such that respective images at the different wavelength components are offset by different amounts of displacements along a direction of dispersion; gathering a first EM wave energy incident on the entrance aperture to an EM detector; gathering a second EM wave energy that exits the exit aperture to the at least one single-pixel detector; and measuring the output of the EM detector and the output of the at least one single pixel detector for reconstructing the EM wave spectrum taking into account an intensity distribution of an incident EM wave on the entrance aperture.

    Abstract: The invention relates to a spectral sensing device (110) and a method for measuring optical radiation (112). The optical radiation (112) provided by the at least one measurement object (114) comprises non-modulated optical radiation (116). The spectral sensing device (110) comprises at least one radiation emitting element (118), wherein the at least one radiation emitting element (118) is designated for emitting modulated optical radiation (120); at least one photosensitive detector (124), wherein the at least one photosensitive detector (124) has at least one photosensitive region (126) designated for receiving optical radiation (112), wherein at least one detector signal generated by the at least one photosensitive detector (124) is dependent on an illumination of the at least one photosensitive region (126); at least one evaluation unit (128), wherein the at least one evaluation unit (128) is configured for generating at least one piece of measurement information about the illumination of the at least one photosensitive region (126) by the optical radiation (112) provided by the at least one measurement object (114) by using at least one modulated detector signal as generated by the illumination of the at least one photosensitive region (126) by a superposition of the modulated optical radiation (120) and the optical radiation (112) provided by the at least one measurement object (114). The spectral sensing device (110) is arranged in a manner that the modulated optical radiation (120) is guided within the spectral sensing device (110) towards the at least one photosensitive detector (124). The spectral sensing device (110) and a method for measuring optical radiation (112) are configured to perform, preferably in a fully automatized fashion, a self-calibration of the spectral sensing device (110) without requiring any predefined reflection target.
