ABSTRACT:
A split-screen spectroscopic imaging apparatus including a fiber optic plate having a light receiving end face on which the photogenic subject is primarily focused by an objective lens and a light emitting end face to which the primarily focused image is transmitted. Total reflection mirrors optically separate the optical path of the image from the light emitting end face into a plurality of optical paths. Coherent filters optically separate the images of the optical paths separated by the total reflection mirrors into images of a plurality of wavelength bands. A two-slop reflection rectangular prism synthesizes the images separated by the coherent filters into a single image by arranging them in a predetermined direction. A reducing optical system optically reduces the magnification of the image from the two-slop reflection rectangular prism. And, a CCD imaging element images the images from the reducing optical system substantially simultaneously by a single imaging face.
