けたことを特徴とする結像光学装置。 The light directed through the input aperture formed in the optical housing is directed through a convex roof mirror, a lens array, a concave roof mirror array, the lens array, the roof mirror, and an exit aperture formed in the optical housing. In an imaging optical device that sequentially guides and emits light and forms an image at a predetermined position, the lens array is a multi-lens array in which a large number of lenses are arranged in a row at intervals and are integrally molded into one thin strip. A light shielding plate is provided between the top of the roof-shaped mirror and the multi-lens array, and a light-shielding plate is provided between the lenses located on a line passing through each optical axis of the lenses with respect to the multi-lens array. An imaging optical device characterized in that a fitting groove for engaging a side end of the light shielding plate is provided in a flat portion of the image forming optical device.
