光学信息处理的理论基础是透镜的傅里叶变换作用.目前这个领域已有许多引人注目的进展,例如对二维信号进行特征识别;改善各种成象仪器的成象质量,消除由于系统或元件本身的象差、离焦、大气扰动、成象仪器与物体之间相对运动所造成的图象模糊;处理综合孔径雷达收集的大量数据等等.光学信息处理装置有时也称作“相干光模拟计算机”.近几年来,发展迅速,每年召开一次国际专业会议报导“光计算”领域的研究成果.
The theoretical basis of optical information processing is the Fourier transform of the lens.Most notable advances have been made in this area, such as the feature recognition of two-dimensional signals, the improvement of the imaging quality of various imaging instruments, Or component itself, aberrations, defocusing, atmospheric disturbances, blurred images caused by the relative motion between the imaging apparatus and the object, large amounts of data collected by the synthetic aperture radar, etc. Optical information processing devices are sometimes referred to as “coherent Light simulation computer. ”In recent years, the rapid development of the annual meeting held an international conference reported“ light computing ”research results.
