mikrolinsearray

A micro-lens array (MLA) is a planar array of microlenses, each with a diameter typically ranging from a few micrometers to a few millimeters. These microlenses are often fabricated using photolithography or other microfabrication techniques. MLAs are used in various optical systems to manipulate light in specific ways, such as in imaging, projection, and display technologies.

One of the primary applications of MLAs is in the field of imaging. In digital cameras and smartphone cameras, MLAs are used to increase the light-gathering ability of the sensor. Each microlens in the array focuses light onto a corresponding pixel on the sensor, allowing for a larger effective aperture and improved low-light performance. This technology is also used in endoscopes and other medical imaging devices to provide high-resolution images in confined spaces.

In projection systems, MLAs are employed to create a uniform illumination on the projection surface. By dividing the light source into smaller, more manageable segments, MLAs help to reduce the Moire effect and improve the overall image quality. This application is particularly relevant in high-brightness projectors used for large-screen displays.

MLAs are also utilized in display technologies, such as in liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays. In these applications, MLAs are used to control the light distribution and improve the viewing angles of the display. This results in a more uniform and brighter image, enhancing the overall viewing experience.

The design and fabrication of MLAs involve careful consideration of various factors, including the lens shape, size, and spacing, as well as the optical properties of the materials used. Advances in microfabrication techniques have enabled the creation of MLAs with increasingly complex designs, leading to improved performance in various optical systems.
