Abstract
Изобретение относится к области оптической спектроскопии. Изображающий гиперспектрометр состоит из узкой щели, расположенной в передней фокальной плоскости объектива, дифракционной решетки, второго объектива, строящего изображение спектра на ПЗС матрице. Щель выполнена в виде полукольца, расположенного вдоль радиальной полярной координаты входного зрачка, дифракционная решетка выполнена со штрихами, изогнутыми в кольца. Данный изображающий гиперспектрометр позволяет получить гиперспектральные изображения высокого разрешения за счет компенсации аберраций, при меньшей, чем у прототипа, стоимости.The invention relates to the field of optical spectroscopy. The imaging hyperspectrometer consists of a narrow slit located in the front focal plane of the lens, a diffraction grating, and a second lens that builds a spectrum image on a CCD array. The slit is made in the form of a semiring located along the radial polar coordinate of the entrance pupil, the diffraction grating is made with strokes bent into rings. This depicting hyperspectrometer allows to obtain high-resolution hyperspectral images by compensating for aberrations, at a lower cost than the prototype.
