MULTI-SCREEN SPECTROSCOPIC IMAGING DEVICE

Title:

MULTI-SCREEN SPECTROSCOPIC IMAGING DEVICE

Document Type and Number:

WIPO Patent Application WO/2002/071011

Kind Code:

A1

Abstract:

A multi-screen spectroscopic imaging device comprises a fiber optic plate (4) including a light receiving end face (4a) on which the image of an object (2) is linearly focused by an objective lens (3) and a light emerging end face (4b) to which the linearly focused image on the light receiving end face is transmitted; total reflection mirrors (6a to 6d) for optically separating the optical path of the image from the light emerging end face of the fiber optic plate into a plurality of optical paths (7a to 7d); coherent filters (8a to 8d) for optically separating the images of the optical paths separated by the total reflection mirrors, into images of a plurality of wavelength bands; a two-slope reflection rectangular prism (10) for combining the images separated by the coherent filters into a single image by arraying them in a predetermined direction; a reducing optical system (12) for optically reducing the magnification of the image coming from the two-slope reflection rectangular prism; and a CCD imaging element (11) for imaging the images coming from the reducing optical system, substantially simultaneously by a single imaging face (11a).
