Thermal IR Multispectral Imaging of Minerals

Using the MS-IR Infrared Camera

For year scientists have used thermal broadband cameras to perform target characterization in the longwave (LWIR, 8-12 micron) and midwave (3-5 micron) infrared.  The analysis of broadband imaging sequences typically provides energy, morphological and/or spatiotemporal information. However, there is very little information about the chemical nature of the investigated targets when using such systems due to the lack of spectral content in the images.

Telops has developed dynamic multispectral imaging systems which enable:

  • Synchronized acquisition on 8 channels
  • At a high frame rate
  • Using a motorized filter wheel

An overview of the technology is presented in this work as well as results from measurements carried out on minerals. Comparison of the results obtained using the information from the different acquisition channels with the corresponding broadband infrared images illustrates the selectivity provided by multispectral imaging for characterization of minerals.
