AOTF controller that monitors output power of a plurality of wavelengths
of an AOTF and scans the frequency of corresponding RF input signals to
an AOTF acoustic transducer and searches for the RF frequency
corresponding to each desired wavelength that provides maximum optical
output for each wavelength. The controller includes a plurality of sensor
inputs for monitoring the power of each wavelength output from the AOTF,
and alternatively, also monitors other AOTF parameters such as
temperature and/or reads AOTF identification performance data that can be
stored in a EPROM on a AOTF housing. The controller includes facility for
input of modulation data, and in response to the data modulates the
corresponding wavelength parameter such as power. A USB bus is provided
for input of programming to the controller, and for output of performance
data from the controller.
