A microlens array is an optical device that has lots of tiny lenses. It can be used to make a light field display.
A microlens array is used in Lytro's cameras.[1]
Each lens in the array has its own optical axis. However, when the array is viewed as a cohesive unit, the lenses form a shared main optical axis.[2]
Thorlabs advertises the sale of microlens arrays as of 2024.[3] Thorlabs has claimed that their lenslet arrays are formed using photolithographic techniques.[3]
The side with the roundings should generally face towards the source of the light. In a display, this means that the user's eye faces the flat side of the array, and the underlying display faces the side with the roundings.
Microlens arrays can be produced using microfabrication techniques.
Microlens arrays can be found in infra-red motion sensors.[4]
Dimensions
Microlens arrays have been produced with a distance between microlenses of about 125 microns, which is 1/8 of a millimeter.[5][3]
To make a plenoptic microlens based display, each microlens should be at the minimum 200 pixels wide and 200 pixels long.
