Laser Speckle Reducers

Description

Optotune’s laser speckle reducers are nothing other than moving diffusers. But the way they are actuated is absolutely unique. Two innovative technologies are offered, each with its own advantages.

Electro-Active Polymer LSR

The basis of this approach is a thin, elastic membrane that carries a lightweight diffuser in its center and four electrodes surrounding it. Actuated at a 90° phase shift, the electrodes induce a circular oscillation of the diffuser in x- and y-direction. The ultra-compact form factor, minimal weight and the absence of noise and vibrations make this technology particularly attractive for hand-held devices. Within a height of less than 1mm, electroactive polymers are used to bring a polymer diffuser into resonant oscillation with e.g. 400µm travel at several 100 Hz. This electrostatic principle is very power-efficient, completely silent and free of vibrations, an ideal choice for hand-held devices.

Reluctance force LSR

The basis of this approach is a single thin steel structure that is brought into resonance by pulsing an actuating coil with current, which generates a strong reluctance force. Thanks to a high q-factor large amplitudes in the range of 800um are achieved at low power consumption even for heavy glass diffusers. Optotune’s LSR-4C speckle reducer has an aperture of 18.5×18.5 mm and is especially suitable for applications where high laser powers and large beam diameters are used. The diffusor is mounted in a thin steel frame. As part of a larger metallic structure the frame is set into motion by the reluctance force, generated by the oscillating magnetic field of a driving coil. If required, the LSR-4C can combine two oscillating diffusors rotated by 90°, realizing optimized despeckling in both directions.
