We proposed a large aperture push-broom static Fourier transform (FT) imaging spectrometer for hyper-spectral imaging. The spectroscopic system was based on the silicon-on-insulator (SOI) platform, consisting of spot size converters, a Mach-Zehnder interferometer (MZI) array, and a detector array. The arm length differences of the 201 MZI arrays are linearly varied. It is one on-chip FT spectrometer operating in a large spectral range from 1100 to 1700 nm with a resolution of 24 cm and small foot print (chip size: 11 mm×15 mm). The waveguide-MZI-based large aperture push-broom FT spectrometer can provide a compact solution for high spectral resolution remote sensing in both the fore-optic lens and the spectroscopic system.
我们提出了一种用于高光谱成像的大孔径推扫式静态傅里叶变换（FT）成像光谱仪。该光谱系统基于绝缘体上硅（SOI）平台，由光斑尺寸转换器、马赫曾德尔干涉仪（MZI）阵列和探测器阵列组成。201个MZI阵列的臂长差呈线性变化。它是一种片上FT光谱仪，工作在1100至1700纳米的大光谱范围内，分辨率为24厘米，占地面积小（芯片尺寸：11毫米×15毫米）。基于波导 - MZI的大孔径推扫式FT光谱仪可为前光学镜头和光谱系统中的高光谱分辨率遥感提供紧凑的解决方案。
