RPI20 parallel interfaceThe RLE system directly produces a 1 Vpp sine / cosine output with signal periods of 316 nm and 158 nm from single and double pass interferometers respectively. The RPI20 interface processes these signals to provide ultra-high resolution positional feedback in parallel word format.

Features and benefits

  • 4096x interpolationDual axis VME
  • Analogue input bandwidth of <6.5 MHz
  • 36-bit parallel format output
  • Up to seven axis capability on one bus
  • Switch selectable output resolutions
  • Addressable registers providing:
    • Position data
    • Card status, inlcluding Liassajous co-ordinates, laser signal strength and system status
  • Compact 110 mm x 72 mm board size
  • Optional dual axis VME host board to enable to the RPI20 to be used in VME system architectures

Specification

Resolution 38.6 picometres (plane mirror system)
77.2 picometres (retroreflector system)
Maximum velocity 1 m/s (plane mirror system)
2 m/s (retroreflector system)
Output signal 36-bit parallel word
