| Abstract: |
| Mentiond importance of SRM nondestruction test and recounts varied measure to improve quality of ICT’s image,especially provide four ways-calibrate light axis, improve signal to noise ratio of system,improve efficiency of detector and suitable filter function.Some results were illustrated by comparing test data and original image from beginning to end.Better effect was got by these measures. |
