Heretofore, there are many literature concerning the measurements of transfer function for a control system, (1) (2) but very few on the topics for an E-0 system especially for the part containing both the sensor and its signal processing. The purpose of this paper is to give a simple new approach to characterize the E-0 transfer function in frequency domain. The main contributions of this approach are namely: (1) A moving target generation, which is made by the light source array is designed to simulate a moving target. The advantages of this set up will give simplicity and high frequency capability. (2) A programmed numerical optimization process, which makes use of the least-squared-error method is established to locate the pole-zero configuration of over all system. (3) An experiment for the TV tracking-centroid system is developed to illustrate the details of this approach. The results reveal the 15 db band width of which at 0.639/um wavelength in low light level condition is 8 Hz. It is suggested that this technique can also be applied for many other E-0 systems such ass infrared, laser and so on extensively.
