7.1.1 Control Panel Camera Tab

The Camera Tab on the Control Panel, shown in Figure 8, provides the ability to modify the Flat
Field mode, the Digital Output mode as well as select the Dynamic Range and External Sync
modes.
Flat-Field-Correction Mode: Photon includes internal mechanisms for periodically
improving image quality via a process called "flat-field correction" (FFC). During FFC, a
small calibration flag rotates in front of the detector array, presenting a uniform temperature
(i.e. a "flat field") to every detector element. While imaging the flat-field, the camera
updates correction coefficients, resulting in a more uniform array output. The video image is
frozen during the entire process, which takes approximately half a second, and it resumes
automatically thereafter. Repeating the FFC operation often prevents the imagery from
appearing "grainy". This is especially important when camera temperature is fluctuating,
such as immediately after turn-on and/or when ambient temperature is drifting. FFC can be
commanded manually at any time using the FFC command in the Control Panel menu bar.
Photon provides two FFC modes for configuring automatic FFC conditions:
