Aim at non-uniformity problem of multi-TDICCD mosaic camera
the synthetically correction algorithms about single TDICCD and multi TDICCDs are studied. First
based on CCD camera characteristic
the principles of TDICCD and non-uniformity are introduced. Then the principle of single and multi TDICCD is analyzed respective
two point correction methods is applied in single TDICCD and ratio average correction method is applied in multi TDICCD .At last
the integrative correction method is discussed. Experimental results indicate that multi-TDICCD mosaic camera is in a condition of 8.4% non-uniformity and it can reach to 2.7% non-uniformity after the correction. This correction method is satisfied the desire of the target of multi-TDICCD camera
and the algorithms has good practicality and efficiency.
