Abstract
In a pattern formation member adopted to a sectioning image observation apparatus which selectively irradiates a light from a light source to a sample, scans the sample, and acquires a light from the sample as a sectioning image, the pattern formation member comprises an irradiation section and a cutoff section, each of the irradiation section and the cutoff section is in a straight pattern, and these straight patterns are disposed alternatively.

A pattern information member adapted for use in a sectioning image observation apparatus that scans a sample with light from a light source, said pattern formation member comprising:
- a rotation disk having a plurality of areas,
- wherein each of the plurality of areas comprises translucent sections and shield sections disposed alternately to form a straight pattern;
- wherein all translucent sections have a same width as each other and all shield sections have a same width as each other around a same circumference of all concentric circles inscribable upon the rotation disk;
- and
- wherein the plurality of areas comprises different straight patterns which are different from each other in at least one of the width of the translucent sections, the width of the shield sections, and orientation.
A pattern formation member adapted for use in a sectioning image observation apparatus that scans a sample with light from a light source, said pattern formation member comprising:
- a rotation disk comprising:
- (i) at least one area having translucent sections and shield sections disposed alternately form a straight pattern;
- and
- (ii) at least one shield area disposed at a portion of the at least one area where the straight pattern would be parallel to a scanning direction according to a rotation of said rotation disk in an observation field to reduce uneven brightness;
- wherein all translucent sections of said at least one area have a same width as each other and all shield sections of said at least one area have a same width as each other along a same circumference of all concentric circles which may be inscribed upon the rotation dish;
- and
- wherein the rotation disk does not include any exclusively translucent area along a same circumference of any concentric circle which may be inscribed upon the rotation disk to include the straight pattern.
