Abstract: A multi-spectrum, multi-channel imaging spectrometer includes two or more input slits or other input for each input channel. The input slits are vertically and horizontally displaced from each other. The vertical displacements cause spectra from the channels to be vertically displaced on a single image sensor on a stationary image plane. The horizontal displacements cause light beams from the input channels to strike a convex grating at different incidence angles and produce separate spectra having different spectral ranges. A retroflective spectrometer includes a convex grating that, by diffraction, disperses wavelengths of light at different angles and orders approximately back along an incident light beam. A single concave mirror reflects both the input channel and the dispersed spectrum. A prism, set of mirrors, beam splitters or other optical element(s) folds the input channel(s) of a spectrometer to enable the input(s) to be moved away from the plan of the image sensor.

Abstract translation: 多光谱多通道成像光谱仪包括两个或更多个输入狭缝或每个输入通道的其他输入。 输入狭缝彼此垂直和水平位移。 垂直位移导致来自通道的光谱在静止图像平面上的单个图像传感器上垂直位移。 水平位移导致来自输入通道的光束以不同的入射角撞击凸形光栅，并产生具有不同光谱范围的分立光谱。 反射光谱仪包括一个凸形光栅，它通过衍射分散光线的不同角度的波长，并沿着入射光束大致向后延伸。 单个凹面镜反映了输入通道和分散光谱。 棱镜，一组镜子，分束器或其他光学元件折叠光谱仪的输入通道，以使得输入能够远离图像传感器的平面移动。

Abstract: A multi-spectrum, multi-channel imaging spectrometer includes two or more input slits or other light input devices, one for each of two or more input channels. The input slits are vertically and horizontally displaced, with respect to each other. The vertical displacements cause spectra from the two channels to be vertically displaced, with respect to each other, on a single image sensor on a stationary image plane. The horizontal displacements cause incident light beams from the respective input channels to strike a convex grating at different respective incidence angles and produce separate spectra having different respective spectral ranges. A retroflective spectrometer includes a convex grating that, by diffraction, disperses wavelengths of light at different angles and orders approximately back along an incident light beam. A single concave mirror reflects both the input channel and the dispersed spectrum. A prism, set of mirrors, beam splitters or other optical element(s) folds the input channel(s) of a spectrometer to enable the input(s) to be moved away from the plane of the image sensor, thereby enabling a large camera or other device to be attached to the spectrometer without blocking the input(s). A mounting mechanism enables a curved optical element to be adjusted through lateral and transverse translations, without requiring a gimbal mount.
