Abstract: Technologies for a high resolution and wide swath spectrometer are disclosed. In the illustrative embodiment, an inverted image slicer converts a linear field of view into a grid shape, allowing for an interferometer of a Fourier transform spectrometer to operate on a narrow range of field of views, improving the average spectral resolution of the spectrometer.

Abstract: A calibration device for a turbidimeter is disclosed. The calibration device includes a body made from a light-permeable material having a first end and a second end defining a length. The calibration device further includes at least one calibration portion defined by a first aperture having a light scattering pattern. The first aperture is oriented perpendicular to the first end, and the first aperture extends into the body a first distance that is less than the length of the body. The turbidimeter is calibrated by inserting one of the at least one calibration portion of the calibration device into the sensing region.
