<p>An image retrieval device is provided with: a first concave lens mirror (7) that collimates scattered light reflected by an object (1) subjected to irradiation, reflects the same as a substantially parallel light ray bundle angled in a secondary scanning direction, and is positioned in an array along a principal scanning direction; a planar mirror (8) for reflecting light from the first lens mirror (7); an aperture (9) that is positioned in an array, and transmits light from the planar mirror (8) through an opening (10) for selectively transmitting light, having a peripheral area therearound which blocks light, and positioned in an array; a second concave lens mirror (11) which receives light that is incident from the aperture (9), reflects the same as focused light, and is positioned in an array; and a light-receiving part which receives light that is incident from the second lens mirror (11), and has a light-receiving region for producing an image in response to the light from the opening (10).</p> |
