In addition to information security and electronics system projects, the Scientific and Technological Research Council of Turkey (TÜBİTAK)Informatics and Information Security Research Center (Bilgem), National Research Institute of Electronics and Cryptology (UEKAE) has interest in the photo-detector sensors and systems. The quadrant photo-detector designed and fabricated entirely by UEKAE has several applications in both military and public services. 

PIN photo-detector (DDA-I) fabrication process was developed by Semiconductor Technologies Research Lab (YITAL) in accordance with the specifications provided by Roketsan These DDA-I sensors developed specifically for Roketsan’s laser-guided missile -CIRIT- have four parallel PIN-diodes on the same silicon substrate.
