The diodes produce a voltage when the light energy is received. Scanning a rotating tire between the X-ray source and the diode arrays forms images. X-rays are projected through the tire and received by a single row of diodes. The diodes collect energy for several milliseconds to integrate the signal. When the integration time is expired, data is read from the diodes by the interface board and sent to the computer.
Diodes are reset and ready to receive X-rays for the next line of the tire to be scanned.
In contrast to early LDA systems, the LDA 2005 gathers raw 12-bit digital data that enters the Host PC from the data acquisition interface board. The LDA 2005 has made possible many enhancements that affect overall performance of the tire X-ray inspection unit. Primarily, the high powered industrial PC that controls the LDA 2005 has contributed to the flexibility of the inspection system. It enables rapid processing and image analysis. Proprietary system software maximizes the potential of each LDA detector.
