Özet
In this work, a low power compact embedded system for steel scanner based miniaturized projection displays is presented. The proposed system is composed of a steel micro scanner, a microcontroller unit, a power amplifier, a 5mW laser with 650nm wavelength and a transistor-based laser driver. The proposed embedded system generates two actuation signals for vertical and horizontal movements of the scanner. The embedded system also generates laser pulses in synchronization with the actuation signals to form a stable and undistorted image. The steel scanner's total optical scanning angles (TOSA) are 5.415 and 3.2729 in slow-scan and fast-scan directions, respectively. Slow scan frequency is 264 Hz, while the fast scan frequency is 2640 Hz. The proposed device can deliver sufficient torque to allow non-resonant operation. Sample images generated using the proposed system are also given.
