Measuring moisture in cotton with Specim FX17 hyperspectral camera

The quantification of moisture is critical for many industrial and research applications. Quantitative models based on spectroscopy are efficient, non-destructive, and accurate for monitoring the moisture content. Hyperspectral cameras also reveal the spatial distribution of moisture, whereas point spectrometers provide only general distribution. In this study, Specim monitored the moisture content of a cotton patch along with its drying.

Detection of adhesives with Specim hyperspectral cameras

Glues and adhesives are widely used in many industrial applications, from packaging and construction to electronics and aerospace, to mention a few.

Glue is expensive, and using just the right amount is crucial as it can save on costs, increase production, and reduce waste.Using the right amount of glue in the right place should be monitored carefully. However, detecting glue can be challenging since most glues are transparent, and standard vision systems based on RGB cameras cannot see them. Hyperspectral cameras offer a more appropriate solution.

The role of white reference in obtaining reflectance data

When converting hyperspectral data into reflectance, a white reference is needed. It measures the incoming light seen by the hyperspectral camera, taking into account the optics’ transmission and the detector’s Quantum Efficiency. The role of white reference is crucial in obtaining good reflectance data with a hyperspectral instrument. This article highlights the importance of adjusting the height of the white reference tile when making measurements.
