6 Σεπ 2024 · Fly Eye Lens, also known as a micro lens array or micro mirror array, is a type of lens body composed of many small lenses (micro lenses). These small lenses are tightly arranged together, forming an array that mimics the structure of compound eyes in insects, especially flies and other insects, hence the name.
22 Νοε 2020 · For people who are nearsighted (center), images from far objects focus too far in front of the retina, whereas for people who are farsighted (right), images from near objects focus too far behind the retina. Eyeglasses solve the problem by adding a secondary, corrective lens.
What is a fly’s eye sheet? A fly’s eye lens is called a fly’s eye because it is how a fly sees his environment. It is a sheet of plastic embossed with a lens array on the surface. The lens array is not a linear lens array like a lenticular, but round lenses nested together in a honeycomb.
Behind the pupil is the lens, a structure that focuses the incoming light on the retina, the layer of tissue at the back of the eye that contains photoreceptor cells. As our eyes move from near objects to distant objects, a process known as visual accommodation occurs.
31 Μαρ 2021 · Fly’s eye arrays are typically used in pairs along with a condenser lens to provide uniform irradiance at the illumination plane. The first fly’s eye array is often called the "objective array" and the second array, along the optical axis, is called the "field array".
The anatomy of the eye is illustrated in this diagram. The lens is attached to muscles that can change its shape so that we can see objects that are close to us, as well as those that are far away. Ideally, the optics of the eye (cornea and lens) produce a picture of the outside world that is perfectly focused on the retina at the back of the eye.
The 'fly eye' lens roughly models what information is collected by a compound eye, but not what the animal actually sees. Each of the tiny lenses in a compound eye collect light from part of the scene in front of them.
