  • Abstract
    A new type of Fourier transform system proposed by the author was realized in hardware and applied to the moving vehicle size detection. CdS photo-sensor array (9 cell units) was used to pick up the moving vehicle image which was transformed into spatial frequency domain. The experimental results showed the peak value of the fundamental component corresponded to the vehicle size.
