The Fiber Optic (UV/Visible) Hyperspectral Imager (FOHSI) is an innovative application of our patented HyperPixel Array imaging spectrometer, designed to capture high resolution spectral data of fast, dynamic processes such as combustion. The Fiber Optic cable allows insertion of the sensor input directly into a machine or combustion chamber.
The design provides 3-dimensional hyperspectral datacubes (2 spatial, 1 spectral) without scanning, allowing high temporal and spectral resolution analysis of transient events.
Fiber optic reformatter captures images and reformats them into 6 slits. Slits are passed through a multislit spectrometer. Data is collected with an image intensified high speed camera at 2,000 fps.
This FOHSI is a custom imaging system designed to monitor short-lived radical species in combustion zones. It incorporates a high-speed image-intensified camera capable of capturing temporal changes as fast as 500 µs.
Key capabilities include 25×36 spatial resolution with spectral data acquisition covering 300-540nm. This enables monitoring of chemiluminescence from short-lived radicals such as OH + , CH + and C 2 +.
