| Abstract: | This article introduced the system of CCD data acquisition on LabVIEW and working theory of linear- CCD. It also discussed noises in linear-CCD and measuring methods of these noises. It expounded that the theory of acquiring data and the driver of data acquiring on LabVIEW. The system errors can be corrected by software. Two methods of acquiring max signals, width of half amplitude on LabVIEW were introduced and advantage and disadvantage were compared. |
