In this research, the wire-type shape memory alloy (SMA) is used for the autofocusing actuator. The main experimental design is divided into two parts. One is the hardware setup another is the software development. At the part of the hardware, we use an actuator and an optical imaging system to set up the focus platform. The temperature is controlled by ARM microprocessor through a Darlington amplifier circuit. At the part of the software, we are looking for focus values as passive autofocus algorithm’s performance indicators to determining the clarity of the image. And we write the Borland C++ Builder (BCB) as a user interface, comparing the image clarity difference between before focus and after focus.
Furthermore, we try genetic algorithms, fuzzy control, steady and unsteady steps to be the rules of focusing to achieve the purpose of autofocus. Finally, we introduce and present the experimental results, and compare the advantages and disadvantages of three focus rules. |
