NIR Spectroscopy and Aquaphotomics Approach to Identify Soil Characteristics as a Function of the Sampling Depth

“…The separation of the samples using NIR based on the sampling area confirmed the preliminary results of another study [22]. The authors found that NIR could effectively determine the differences among three different soil samples collected at the same depth (total explained variance was over 85%) using the whole spectral range between 908 and 1,676 nm.…”

“…The soil samples were dried and sieved, following which the carbon and nitrogen content of the samples was determined using an elemental analyzer (LECO CHN 628), according to the method described by Mura et al [22].…”

Review of portable near infrared spectrometers: Current status and new techniques

“…It weighs 58 g and uses a linear array detector; each pixel element of the detector senses the spectral signal at a specific wavelength. 26 By contrast, NIRONE Sensor S does not use a slit but employs a fully programmable filter. It only operates using selected wavelengths and chooses a single-element InGaAs detector instead of a linear array.…”

Efficient and stable near-infrared Y2Mg2Al2Si2O12:Cr3+ phosphor: analysis of the luminescence source by a site elimination strategy

“…As an integral part of the electromagnetic spectrum, broadband NIR light plays an unprecedentedly important role in biological detection, laboratory instrumentation, chemical industry, optoelectronic devices, and medical diagnostics. [1][2][3][4][5][6] In particular, NIR light in the 700-1100 nm region is known as the first biological window, which can be used in bio-imaging and non-destructive testing due to its considerable penetration depth in biological tissues besides plant growth and night vision application. [7][8][9] Traditional NIR light sources such as incandescent lamps and halogen lamps have a series of problems like large size, low output, and high energy consumption, which hinder the further development of portable and integrated NIR technology.…”
