INTERFERENCE SPECTROMETER Russian patent published in 2007 - IPC G01J3/45 G01B9/02 

FIELD: the invention refers to the field of technical physics connected with development of video spectral apparatus designed in the first turn for solving tasks of remote sounding of the Earth from mobile platforms.

SUBSTANCE: the interference spectrometer has located along the pass of the beam an input diagram, a collimating objective, and a beam splitter fulfilled out of two similar lenses whose working edges are aluminized and the angle between the aluminized and transparent edges is right. In the rear focus of the input objective there is a slit located in the plane of the input edge of the block of prisms, the width of the slit is equal to the width of pixels of the used matrix photo receiver. The input edge of the prism light divider is aluminized and a cylindrical lens is installed between the output objective having an input slit in its front focus and the matrix photo receiver. At that the matrix photo receiver is located in its rear focal plane.

EFFECT: the invention allows receiving hyper spectral cube of data including also besides spectral resolution a spatial resolution along two coordinates of the space of objects.
