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:
