摘要： An optical cantilever for SNOM which emits and/or detects light through a fine aperture, is excellent in mass-productivity and uniformity and permits a fast observation without damaging even a soft sample, characterized by comprising a base (1), a cantilever (2) extending from the base (1), an optical propagation unit (5) and an optical propagation tip (3) of a dielectric penetrating the cantilever (2) and formed so as to protrude beyond the side opposite to the base of the cantilever with its tip end sharpened, a light shielding film (6) covering around the tip-sharpened dielectric, and a fine aperture (4) formed at the tip end of the dielectric.

摘要： There is provided a near-field optical memory head for recording and/or reproducing information on a recording medium by utilizing near-field light which is a near-field optical memory head having a compact constitution and is suitable for mass production and array formation. According to the near-field optical memory head 11, in a planar substrate formed by penetrating at least one hole in a shape of an inverted pyramid such that a top portion thereof constitutes a very small aperture 4, a near-field light forming system for forming near-field light at a recording medium 1 and a near-field light detecting system for guiding propagating light 10 provided by interactively operating the formed near-field light with the very small aperture 4 to a light detecting element are integrated.

摘要： The present invention provides optical pattern recognition apparatus comprising means for generating a coherent image of a joint input image (3) including a plurality of reference images R i and a signal image S by applying a coherent light beam (1) to the joint input image. Fourier transform means (4) are provided for transforming the coherent image into a joint Fourier transform image, which is then converted by a spatial light modulator (5) into a light intensity distribution. Means (8, 9) are also provided for determining a correlation coefficient between each of the reference images and the signal image based on the light intensity distribution. Feed-back means (2, 11) respond to an output from the correlation coefficient determining means for adjusting the intensity of light applied to the joint input image for generating the coherent image.
