Time-Resolved Image

A time-resolved (or framing camera) image can be viewed by selecting one simulation time and clicking on the Time-Resolved Images button in the Visualizer main window. Initially, the unfiltered image is shown.

Other images types may be selected from the Image Type combo box. The list of available images will depend on what was specified in the workspace for the simulation. If more than one image is available for a particular image type, they will be listed in the combo box beneath the image type combo box; e.g. for the Additional photon energy images, the photon energies used will be listed. When an image type has been selected, clicking on the Update Plot button will show the image.

The quantity displayed in the image depends on the Image Type selected:

• Unfiltered image: frequency-integrated specific intensity (erg/cm²/ster/s)
• Fast Framing Camera image (FFC): frequency-integrated specific intensity convolved with framing camera filter response function (units depend on response function units).
• X-ray diode image (XRD): frequency-integrated specific intensity convolved with the XRD filter response function (units depend on response function units).
• Monochromatic image: specific intensity at specified Additional photon energy (erg/cm²/ster/s/eV).

For an overview of how the flux at the detector is computed, see Appendix on SPECT3D Detector Fluxes.

Images at other simulation times are displayed by:

• Selecting a time from the Simulation Time box.
• Selecting a time on the main window and clicking on the Time Resolved Images button.
• Using the Cycle Sim. Time controls to step through the available simulation times.

  

  Functionality from left to right:

  • Go to the first time step.
  • Go to the previous time step.
  • Step backwards through the time steps.
  • Stop stepping through the time steps.
  • Step forwards through the time steps.
  • Go to the next time step
  • Go to the last time step.

For a circularly symmetric detector, a linear plot of the intensity vs. radius can be shown by selecting the Radial line plot button in the Image options panel.

The current spatial resolution is shown in the Resolution parameters panel. The value can be changed by clicking on the Edit... button. See Spectral and Image Resolution.

For information on how to modify the plot parameters or save images from the graph, see the PrismPLOT Users Guide.
