OJCS “CST” developed optoelectronics instruments and systems for implementation of nondestructive testing on the railroad transport objects. The most interesting became development of freight rail cars wheels pairs thermovision testing system “Teploscan” and speed data acquisition system “BLIK” for contact wire image recording. The systems were tested and utilized on the objects of Moscow Railroad.
TeploScan” is optoelectronics scanning system utilizing far infrared part of spectrum.
The «TeploScan» system is designed to detect micro-cracks in the wheels, trucks and rail cars frames and determines failures of brake system and axle units.

“BLIK” system – electro-optical scanning complex.
The “BLIK” system is designed for remote diagnostics of the contact wire in a railway power network from aboard moving railcar laboratory. The system is mounted on the railcar and allows to measure the average wear of contact wire and to identify places of local high wear at rates up to 110 km / h.
The system is in operation on Moscow railroad (OJSC “RZD” affiliated company) since 2006.
