LIU Jun, ZHONG Xian-xin, LI Zhi-min. Correction of high-speed tri-CCD color disorder[J]. Editorial Office of Optics and Precision Engineering, 2004,(1): 107-112DOI:
the causes of high-speed tri-CCD color disorder were analyzed
and several approaches including prismatic decomposition
exposure controlled by asynchronous trigger clock
and correction by software
are suggested for correction of high-speed tri-CCD color disorder. A prism splitter can be used to enable tri-CCD to receive red
green and blue beams separately so that color disorder can be avoided. An asynchronous clock can be used to control the exposures so that the sequence and delay of tri-CCD exposures can be adjusted to avoid color disorder. Real-time correction of color disorder can be achieved through software modification using data redundancy and data relocation technology. Substantiations made with a BASLER L301bc tri-CCD showed that the quality of images was significantly improved.
