In this work, we present an experimental approach for generating perfect optical vortices by using of phase masks of three levels with shape of axicon and spiral phase functions, which are displayed in a transmission liquid crystal
spatial light modulator. The intensity and vorticity of the POVs are measured with a CMOS camera and the far-field diffraction pattern through an equilateral triangular slit, respectively.

For this work, we used a PLUTO-Telco
spatial light modulator (SLM) from HOLOEYE, Inc.

For those kinds of problems, Prof Silberberg and colleagues at the Weizmann Institute of Science in Israel have pushed the limits of what
spatial light modulators (SLMs) can do.
The beamlets are subject to a
spatial light modulator and are recollimated.
A promising alternative arrangement dispenses entirely with the need for an active transparent panel, as well as obviating the requirement for a partly silvered mirror, through the use of a
spatial light modulator such as the Digital Micromirror Device (DMD) developed by Texas Instruments.
Using a 20-element transmissive
spatial light modulator (SLM) ahead of the summing lens, each delay may be individually monitored to provide closed loop delay control.
Using an instrument called a
spatial light modulator to twist the beams, the researchers sent as many as four concurrent beams, transmitting data at speeds up to 1.6 trillion bits per second, through their custom fiber.
They used a liquid crystal device, which allows precise control of light, called a
spatial light modulator (SLM), to manipulate 64-femtosecond-long laser pulses being projected onto a layer of paint.
