The invention discloses an experimental system for detecting wave front aberration. The experimental system comprises a simulated eyeball, a micro-lens array, an observation screen, a horizontal optical seat, a light source, a converging lens and a cylindrical cultivation tray, wherein the simulated eyeball is mounted on the horizontal optical seat; the micro-lens array and the observation screen are mounted on the horizontal optical seat through a height-adjustable mounting bracket; the diameter of the periphery of the converging lens is equal to that of the round surface of the cylindrical cultivation tray; the cylindrical cultivation tray is made of a transparent material, and silica gel covers the round surface of one end of the cylindrical cultivation tray; a round hole mounting position capable of detachably mounting the converging lens or the cylindrical cultivation tray is arranged at one end of the simulated eyeball; the light source is mounted on the inner wall of the simulated eyeball; when the converging lens is mounted on the simulated eyeball, the light source is positioned at a focal point of the converging lens; when the cylindrical cultivation tray is mounted on the simulated eyeball, one end, covered with the silica gel, of the cylindrical cultivation tray is positioned in the direction far away from the light source; a plurality of sub-lenses are arranged on the micro-lens array, and the observation screen is positioned at a focal plane of the micro-lens array.
Description
technical field [0001] The invention relates to the technical field of teaching experiment products, in particular to a wavefront aberration detection experiment system. Background technique [0002] The human eye is an optical system with aberrations, including not only traditional low-order aberrations such as defocus and astigmatism, but also high-order aberrations such as spherical aberration and coma. Wavefront aberration is defined by the difference between the actual wavefront and the ideal unbiased wavefront. When there is no aberration, the plane wavefront entering the human eye can converge into a point on the retina, while the actual human The optical system of the eye is not perfect, resulting in deformation of the outgoing wave surface, which is no longer an ideal spherical wave surface. The optical path difference between this ideal wavefront and the deformed actual wavefront is the wavefront aberration of the human eye. In order to improve the visual imaging...
