Abstract

Solid-state photonic systems based on CCD imagers are used in home, industrial, medicine, and scientific instrumentations. The famous performance of CCD's in high sensitivity, size, weight, power consumption, wide spectral wave-length range, and high resolution allow to apply their for measuring some parameters and reading an image information of moving transport objects. In the area of railway transport, it's very important to read car numbers during its motion with velocity to 160 kph. Our investigations have shown that a photonic system including TDI CCD (time-delay and integration CCD) and the special TDI CCD velocitimetric sensor may be used for reading and identification of car numbers. This system may be also useful for measuring car parameters on classification humps. Unlike usual radiolocation sensors which today are used in classification humps the proposal system is passive and it may be stood over railway hump.
