New Wide Angle Electro-Optic Laser Scanners Enable Optical Sensors on Previously Inaccessible Platforms

Not Accessible

The world has long sought an electro-optic (EO) alternative to mechanically moving lenses and/or mirrors. Opto-mechanics can impose significant limitations on many important performance criteria including: cost, size, weight, vibration immunity, power consumption, speed, and device lifetime. To help alleviate this we have developed a new EO architecture that provides simple and cost effective electro-optic control over a beams direction, focus, and/or delay. For example, in this paper we present an EO laser scanner with a 40°×10° field of regard. The output angle may be voltage set to any value within this field of regard with only three control electrodes. These scanners, and other devices enabled by our new EO architecture, have very low power consumption, are small, fast, rugged, and simple to use.
