Fast steering mirrors

Overview

Optotune’s disruptive 2D fast steering mirror solutions offer completely new design and integration possibilities for scanning and field of view expansion.

Advantages:

• Large clear apertures and beam angles

• 2D beam deflection with a single optical element (reduced reflection loss, no beam-shift)

• Robust voice-coil actuation

• Optical real-time position feedback

• Compact & lightweight

• Customized coatings available

Dual axis fast steering mirror (FSM) with position feedback

Optotune’s dual axis fast steering mirror (FSM) offers the benefit of large deflections and large mirror size in a compact package. The actuator is based on proven voice-coil technology. A built-in position feedback allows it to be accurately controlled with a standard PID controller. The virtual rotation point of our 2D mirrors is close to the mirror surface which makes 2D scanning straight forward. We offer either two non-resonant axes or a non-resonant axis in combination with a resonant axis. The first option is ideally suited for vector scanning and point & shoot applications, the latter is ideal for fast raster scanning.

Optotune offers the MR-E-3, a full development kit including the mirror, control electronics and software.

Applications:

• Automotive (LiDAR, dynamic headlights, ADAS)

• Machine vision (field-of-view expansion, zoom)

• Free-space communication

• Biometric (eye-tracking)

• Diagnostics (e.g. OCT, Fundus camera)

• Metrology

• 3D printing

FOV expansion and AOI selection

Field-Of-View (FOV) expansion and Area-Of-Interest (AOI) selection with a MR-15-30 dual-axis VCM: The standalone camera on the right is equipped with a wide-angle objective to capture the overall scene. The camera on the left, equipped with a narrow-angle tele lens, looks onto the mirror and allows to “zoom-in” and select a small AOI out of a 100° optical FOV.

Applications:

• Security applications

• Surveillance and face-tracking in airports and other public spaces.

• Inspection
