摘要
提出了一种四波段空间调制器获取目标多光谱图像的方法,给出了其结构设计、制备方案;讨论了该方法的编码和解码原理并进行了模拟实验,验证了利用它进行多光谱照相的可行性。结果表明,该方法克服了传统多光谱摄影中采用"多波多路"方法的系统复杂、造价高和实施困难的缺点。
A novel technique to acquire the object multi-spectral image by using the 4-channel spatial modulator is proposed and experimentally demonstrated. The configuration design and manufacture scheme are also presented. We have discussed about the encoding and decoding theories and performed simulation experiment to testify the validty of its applications in multi-specral photography. Our proposed scheme overcomes the shortages of traditional multi-spectral photography, inclucling the system complex,high cost,and low feasibility of the ＂multi-wavelength multi-channel＂ method.
