Abstract:
1. A hyperspectral imager comprising: a first optical sub-system; at least one slit element; said first optical sub-system being capable of imaging, onto said at least one slit element, electromagnetic radiation emanating from a source; a second optical sub-system; said second optical sub-system being capable of substantially collimating, at a center plane, electromagnetic radiation emanating from said at least one slit element; at least one reflective dispersive element located substantially at the center plane; said second optical sub-system also being capable of imaging, onto an image surface, the electromagnetic radiation reflected from said at least one reflective dispersive element; at least one detecting element located substantially at the image surface; said at least one detecting element being capable of detecting dispersed electromagnetic radiation reflected from said at least one reflective dispersive element; a first sub-housing; a second sub-housing; a third sub-housing;
