A Portable Reflectance Spectrometer for Surface Inspection.

Portable Raman spectrometer – design rules and applications

Raman spectroscopy has become more popular due to its new prospective field applications in forensic sciences, war against terrorism, environment protection and other field chemical analysis. Raman spectrometers can be miniaturised to portable devices and their price is decreasing due to development of optoelectronics components. Unfortunately, this technology has still numerous limitations tha...

The design, characteristics, and first test flight results are described of the Portable Remote Imaging Spectrometer, an airborne sensor specifically designed to address the challenges of coastal ocean remote sensing. The sensor incorporates several technologies that are demonstrated for the first time in a working system in order to achieve a high performance level in terms of uniformity, sign...

Free-Form Surface Matching for Surface Inspection

Used-oil Analysis Using a Portable FTIR Spectrometer

In modern high-tech machinery, lubrication has nearly the same signifi cance as the machine itself. Its main function is to minimize wear on moving parts even in the harshest environments. Due to its essential role in modern engines lube oil degradation can lead to costly failure of the equipment if not detected at an early stage. A continuous oil condition monitoring program helps to avoid unn...

A Fast Smoothing Algorithm for Post-Processing of Surface Reflectance Spectra Retrieved from Airborne Imaging Spectrometer Data

Surface reflectance spectra retrieved from remotely sensed hyperspectral imaging data using radiative transfer models often contain residual atmospheric absorption and scattering effects. The reflectance spectra may also contain minor artifacts due to errors in radiometric and spectral calibrations. We have developed a fast smoothing technique for post-processing of retrieved surface reflectanc...
