ATS9353: On-FPGA FFT
ATS9353 On-FPGA FFT option provides the ability to do real-time FFT signal processing using the ATS9353 on-board FPGA. Note that only one input can be processed.
Up to 2048-point FFT length is supported. A user programmable complex windowing function can be applied to the acquired data before FFT calculation.
The complex FFT output is converted to magnitude in single precision floating-point format. A logarithmic output is also available.
Output formats are:
10 * Log of amplitude
Square Root of amplitude
These outputs provide more than sufficient image resolution in typical OCT applications.
If other outputs, such as phase or multiple channel FFT, are required,
ATS-GPU-OCT or ATS-GPU-NUFFT can be used.
