The CDD Linear X-ray detector is an integrated detection module with a linear diode array up to 1024mm in length.










It has the following features :

• Available in diode pitch of 1.6mm, 0.8mm, 0.4mm, 0.2mm
• Data interface RS422 pixel rate of up to 4MHz
• Scan rate from 50 to 4000 scans/sec
• Output resolution of 8 to 12 bits as standard
• Control interface USB 2.0 as standard, RS232 optionally
• Multi channel radiographic trigger
• Scan rate fixed or synchronous to external clock
• Pixel output normalised by internal DSP processor
• Output translation tables provide gamma law
• All cables exit from end of module for easy connection

Notes

1. Maximum speed is specified for active length up to 512 mm.
2. Dynamic Range is defined as saturation signal/RMS noise, normal detector sensitivity.
3. Digital interface has 16 RS-422 I/O lines for data, but user can select actual data to be 14,12,10 or 8 bits. The default value is 8 or 12 bits
4. User can designate radiographic trigger outputs by specifying Window left, Window right and Threshold.
