Internal Electronics and Processing

Newly designed electronics now allow the bit depth of the internal processing to be raised from 10-bit to 16-bit, thereby rendering addi- tional bit depth conversion unnecessary. This enables the processing of all 16-bit image data without any compression, from the file loader all the way down the data path to the D/A converter (digital-to-analog converter).

The implementation of commonly-used FPGAs (field-program- mable gate arrays) on the electronics board results in improved data handling and eliminates image transfer errors. In combination with the CAN bus protocol, this speeds up both internal communication and processing, while also making the system safer.
