Compact Optical Beam Scanner

The article titled “Demonstration of a compact double-reflection transmissive beam scanner operating at 1550 nm wavelength” by Jordan L. Baker et al. presents a novel compact beam scanner. It utilizes two wire-grid polarizers and a 45° Faraday rotator, enabling a reflective beam scanner with a straight-through optical path, ideal for constrained spaces like endoscopes or wearable devices. The prototype demonstrated high efficiency (>73%) across a 90° scanning range for vertically polarized light, offering potential for further optimization and miniaturization for practical applications.

The article lists several applications for the compact double-reflection transmissive beam scanner, emphasizing its suitability for environments where size and weight constraints are critical. Specific applications mentioned include:

1. Endoscopic Applications: For minimally invasive medical procedures requiring compact and efficient scanning devices.
2. Airborne Systems: Particularly useful in drones and other aerial vehicles where payload weight and size are limited.
3. Vehicle-Mounted Systems: Enhancing autonomous driving technology with compact, high-efficiency scanners.
4. Wearable Devices: Potentially suitable for augmented reality displays and other portable optical systems.
5. Portable Applications: General use in any situation where a small, lightweight scanning solution is needed.

The scanner’s compact size, high efficiency, and large scanning range make it a versatile tool for these and potentially other applications in fields requiring precision optical scanning.
