我们展示了一个紧凑的实时光学图像相关器使用二极管激光器和半绝缘GaAs/AlGaAs多量子阱(SI-MQW)设备作为全息元件。当入射到SI-MQW器件上的功率仅为3 mW时,在1 μs内获得相关性,并且可以在2 μs内快速擦除,这使得能够实现3 × 105相关性/s的系统成为可能。我们还表明,图像可以存储的时间长度可控(2-25 μs),这提出了使用的SI-MQW设备作为数据或图像缓冲存储器的可能性。
We demonstrate a compact real-time optical image correlator using diode lasers and a semi-insulating GaAs/AlGaAs multiple-quantum-well (SI-MQW) device as the holographic element. With only 3 mW of power incident upon the SI-MQW device, the correlation is obtained in 1 μs and can be erased in as fast as 2 μs, which presents the possibility of a system capable of 3 × 105 correlations/s. We also show that images can be stored for a controllable length of time (2–25 μs), which presents possibilities for the use of the SI-MQW device as a data or image buffer memory.
