Spatial Light Modulator Phase

Holoeye s spatial light modulator systems are based on translucent lcd or reflective lcos liquid crystal microdisplays.

Spatial light modulator phase. 4 the most versatile type of slms are phase only slms which are capable of reconfiguring the phase retardation. Spatial light modulators slms which are devices used to manipulate the phase of an incident wave front are prolific in fields such as optical trapping dynamic diffractive optical elements and display technology. For maximum phase shift values refer to the table to the upper right. A spatial light modulator slm is an object that imposes some form of spatially varying modulation on a beam of light.

Meadowlark optics designs develops and manufactures an extensive range of high quality polarization systems and components including liquid crystal devices. Spatial light modulators allow using a special type of phase shifting method. The squares are set 44 levels of grey. Hex spatial light modulator our transmissive hexagonal array slms are designed for adaptive optics applications the two dimensional array of liquid crystal variable retarders acts as a real time programmable phase mask for wavefront correction of a linear polarized source.

The reference mirror is unblocked and the polarizers are removed. A four square mask shown in figure 3a is sent to the lcos. Spatial light modulators slms have widespread applications ranging from three dimensional video projection and additive manufacturing to quantum and adaptive optics the most versatile phase only slms are capable of reconfiguring the phase retardation of light transmitted through or reflected from each pixel without changing its intensity. Each spatial light modulator includes a built in slm panel with independent horizontal and vertical tilt adjustment of 3 2.

Of the many challenges inherent to using slms one of the most ubiquitous is the calibration of the device s phase shifting mechanism.

The pluto 2 1 phase only spatial light modulator slm consists of a driver unit with standard digital video interface hdmi and a phase only lcos liquid crystal on silicon microdisplay with full hd resolution 1920 x 1080 pixel and 8 µm pixel pitch leading to an active area diagonal of 0 7 with aspect ratio of 16 9. These spatial light modulators provide far more pixels than lower order phase modulators such as segmented or deformable mirrors.

Spatial light modulators slms have widespread applications ranging from 3d video projection 1 and additive manufacturing 2 to quantum 3 and adaptive optics.
