Our standard adaptive optical systems are based
on Windows OS, high-voltage amplifiers and
digital-to-analog converters (DAC) serving as
interface between a PC and an amplifier. A number
of interfaces and amplifiers are available, that
allow to control high-voltage deformable mirrors
with up to 2 kHz frequency, voltage up to
400 V with a precision of 8 (PCI), 12 (USB), or
16 (Ethernet) bits.
PCI boards allow to control up to 24 channels
with a single board, the number of boards per
PC is practically unlimited. The refresh time
is better than 1 microsecond per ch annel, all
channels of the board can be controlled independently
in any order.
A single USB DAC or Ethernet DAC module
allows controlling 40 channels with refresh frequency
of 1 or 2 kHz and precision of 12 or 16
bits. These modules can be used in parallel to
control 80, 120... etc. channels with refresh frequency
of up to 2 kHz.
