The kSA 400 analytical RHEED system performs both static and time-resolved data acquisition and analysis. Because the kSA 400 software has so many features and capabilities we have listed only a summary of the most prominent features and capabilities below.
 Line profile fitting: accurately determines streak spacing/in-plane lattice spacing.
  FWHM / in-plane coherence length determination.
Time-resolved acquisition: line scan and column scan modes, in-plane lattice spacing, and coherence length is monitored during growth, annealing, etc., yielding what we term "strain profiles" and "domain profiles".
Multiple RHEED oscillation monitoring: The user may monitor up to 8 different diffraction orders, thereby determining the phase difference between oscillations of different diffraction order. Rate/thickness determination is easily determined since the elapsed time during growth is accurately monitored (to within 0.01 sec accuracy.)
In-plane spacing, coherence length, and intensity oscillations: all monitored simultaneously during growth, so that all three properties are determined.
Growth rate determination: three different techniques may be used to analyze the RHEED intensity oscillations. Specifically, Fast-Fourier Transform (FFT) analysis, extrema counter analysis, and damped sine wave fitting analysis can all be used and compared for accurate growth rate and thickness analysis. These techniques can be used post acquisition or in real-time. Growth rates can be sent as an output for use in process control.
Manual Tracking: In some situations such as during phase transitions, spots may move out of range for automated tracking. Manual tracking allows the user to reposition tracking boxes over the desired spot.
 3D image plotting: shows evolution of growth in 3D for static diffraction images, evolving line scan, column scan, or dual scan images which shows evolution of growth in 3D.
Image Processing Library: A plethora of image processing routines can filter live video, single images, Scan Mode images, or movies. Filters include 2D FFT, 2-image manipulation (subtraction, addition, etc.), edge detection, median filtering, band pass filtering, contrast maximization, rotation, gamma correction, logarithmic scaling, cropping, and many more.
Data analysis library: a multitude of data processing routines are availalbe, including band pass filters, Gaussian, Lorenztian, polynomial, and cubic spline fitting, multiple derivative, cropping, and many more.
