Three aspects of optical processing are discussed. The three aspects are: (1) the potential of this emerging technology; (2) the major limitations preventing wide scale implementation of optical processors and the importance of future research in these areas is emphasized; (3) the importance of nonlinear optics in developing optoelectronic interconnects for VLSI.
By using a least squares identification algorithm, a multiloop approach is taken to effectively model the response characteristics of the motion sensors. The inputs to the model include the possible sources of information provided to the human via his motion sensing system. One input models the response of the angular acceleration sensors (second derivative of position) and the second input models the response of the linear sensors (sine of position). The third input is the visual display error provided to the human in the closed loop tracking experiment. Data from a roll axis tracking simulation were analyzed. The major source of pilot lead under the motion mode of operation is discussed for control of plants in which motion information improved performance and in which there was no improvement in performance.
