Lightform, Inc: Hyperspectral Imaging
LightForm, Inc. http://www.lightforminc.com/ markets a spectral imaging system (under the trade name of PARISS) for use in image segmentation, differentiation, identification and quantification. A sample is typically imaged through a microscope or other optical instrument. It contains two CCD cameras which are coupled to a Windows machine through a IEEE-1394 interface. One camera displays an image that the user would normally observe through the instrument eyepiece (Observed Image) while the other displays a spectrally derived image (Hyperspectral Image), derived from a segment of the Observed Image.
The following features are provided by the PAC developed software:
- Control of camera functions (e.g. gain, contrast, exposure time and picture acquisition).
- Spectral classification based on cross correlation to aid in identifying sample content.
- Reduction of the spectral image to a series of intensity plots versus wavelength for use in evaluating sample content.
- Low pass filtering of spectral intensity plots to improve the signal-to-noise ratio.
- Image display using false color image enhancement. • Basic image arithmetic functions such as addition, subtraction, division and multiplication.
- Save raw and mathematically manipulated images to files.
- Automatic scanning of the microscope slide holder (stage) to automate image data collection.
