Research Abstract

Imaging by particles(l. 80um in diameter)of polystyrene(PSt)latexes has been investigated under drying by means of a microscope. XVhen a few drops of a dilute aqueous solution of the purified PSt latexes ; were dried on a cover glass below the minimum film-forming temperature, the close-packed structure of PSt particles in a layer was easily formed extending over a wide range. The arranged PSt particles all(about 3, 000 pieces)within a sweep of a microscope imaged an object like a compound eye. This means that a latex particle is the smallest optical lens in the world. As an application of particle lenses, we took up an imitation of a compound eye of insects. The imaging by Moir6 patterns between the same polymer sheets arranged closely micro-convex lenses(O. 25mm in diameter)has been investigated. It was found from the results that the Moira unit patterns have the function making images on the polymer sheet(2nd CL-sheet)at the opposite side against an object. The images appeared in the unit cell patterns falling down at 90+rheta゚ to the rotational direction of the 2nd CL-sheet, where rheta is the rotation angle of the 2nd CL-sheet. The imaging size decreased suddenly with the increase in rheta of the 2nd CL-sheet. This contrivance was based on an interesting matter that several thousand convex lenses in a hexagonal unit cell pattern by Moire fringes in the polymer sheet(lst CL-sheet)at the object side make an inverted image in each convex lens, and the numerous inverted images in the 1st Cl-sheet are summarized only one image by several thousand convex lenses in a hexagonal unit cell pattern by Moirefringes in the 2nd CL-sheet. This fact gave us a very important hint to imitate a compound eye of insects. The artificial compound eye will be made using latex particles at some future time.
