The flat field corrections FPN and PRN U assu m e a linear resp onse to the am ou nt of light by the sensor,
ou tp u t nod e, analog am p lifier, and analog to d igital converter. To correct any non -linearity in this system
of com p onents a Look-Up Table (LUT) has been im p lem ented in the FPGA for each tap im m ed iately after
the ADC. The LUT ad d s a signed valu e (-256 to +255) ind exed by the 10 MSB of the inp u t valu e.
Calibrate Input LUT
Calibrates the cu rrent inp u t look -u p table for correcting non -linearity in the analog chain (CCD sense
nod e and analog-to-d igital conversion).

This com m and calibrates all
tap s w ithin the ROI.
To calibrate:
Place a w hite reference in front of the cam era. This is sim ilar
to a PRN U calibration.
In ad d ition:
Use the

Use the

w hich p ixels are u sed for calibration. If a tap is not in the
region of interest, then it w ill not be calibrated and left at
cu rrent valu es.
