The model of device with a diagonal of 42” was developed and made with 4K TV image technology and simultaneous detection in near infrared. The control of individual system modules was carried out on RaspberryPi microcomputers without typical operating system. The functionality of a conventional large-format display with unlimited multi-touch, QR code scanner, and a document scanner has been achieved in one housing. Luminance distribution tests were carried out in accordance with ANSI requirements and infrared radiation for detection work.}, type={Article}, title={Analysis of irradiation in OptiTouch system with optical detection}, URL={http://www.journals.pan.pl/Content/132834/PDF-MASTER/OPELRE_2024_32_4_M_Zajkowski.pdf}, doi={10.24425/opelre.2024.151990}, keywords={optical detection, irradiation, optical guide, display}, }
