Equipment for quality research of imaging devices based on multirow matrix photodetectors with time delay and accumulation M. G. Mazin, P. S. Lazarev, G. G. Deeva, V. N. Solyakov, K. A. Khamidullin, A. D. Judovskaya Orion R&P Association, 46/2 Enthusiasts highway, Moscow, 111123, Russia E-mail: orion@orion-ir.ru The stand for study of imaging devices based on multirow matrix photodetectors with time delay and accumulation has been developed and fabricated. <...> It has been used the criterion for estimation of imaging devices quality: broadening a line spread function, which appears under different unmatched work errors of scanner and digital processing unit. <...> PACS: 42.79Sz, 8530.-Z Keywords: time delay and accumulation, FPA, line spread function, TDI. <...> Для оценки качества формирователей сигналов изображения использован критерий: уширение функции рассеяния линии, возникающее при различных ошибках несогласованной работы сканера и блока цифровой обработки сигналов.! <...>
