What is the spatial light modulator?
Spatial light modulator (SLM) uses the input of an electrical or optical signal to change light and create image as quickly as several times per millisecond. This can be found in many different variants and is used in a wide range of optical devices, including the projector, television or other video and graphics display. There are single and two-dimensional types, both with pixels, basic elements of any image displayed on the screen. Many spatial light modulator varieties can perform electrical or optical functions individually or combine them in one modulator.
The liquid crystal is often the medium used by the spatial light modulator, while the control circuit processes the data into the pixels field for each frame. Two -dimensional types are used in video projectors, but SLM can also be used in many different applications. One species, known as a variable electrooptical mirror, is suitable for optical systems such as rays, shutter and mirrors. Can be usedT in highly reflective systems and made on such small scales that modulators can be integrated into windows that can relieve and darken. Micromirror devices can be built into individual chips used in scientific equipment such as high -performance lasers.
Depending on the application, SLM can work with wavelengths including infrared radiation. Ultraviolet and short, medium or long infrared wavelengths can also be used to modify the specific wavelength in the light spectrum. Spatial light modulator is sometimes used in an effort to control the direction of laser beams, to repair the deviation of light waves and for processing and analyzing images. It can also change the amplitude or phase of light, or both if the functions are best suited to the application.
spatial light modulator can provide such an accurate check -up that engineers are considering itsUse in optical calculations and storage of holographic data. The light can be adjusted to individual pixels. The modulator and the element of the liquid crystal can be built on a single silicone chip for placing on the components of the circuit board for computer graphics cards. Images can be transmitted at very high speeds across digital video interfaces because SLM processes thick pixels and allows a very high display for users. Phase rates can be as fast as less than milliseconds, so high -speed and high -quality video can be possible for all types of computers and mobile devices.
