Long-range and High-sensitivity Detection
Optical remote sensing and communication involves gathering and transmitting data over long distances using optical methods, such as LiDAR, long-range distance sensing, and free-space communication. Ensuring high-quality signal transmission with minimal data loss is therefore crucial. Castor Optics' double-clad fiber couplers and advanced optical components support such applications by providing low-loss illumination and enhanced signal detection through multimode channel(s), enabling longer ranges and higher sensitivity.
Enhancing LiDAR Performances
LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser light to measure distances or detect objects precisely. Its most basic form works by emitting laser pulses and measuring the time delay between the emission and the detected back-reflection after hitting an object. Based on the time delay and the speed of light, LiDAR calculates precise distance measurements. LiDAR is commonly used in autonomous vehicles, topographical mapping and geospatial surveying, archaeology, environmental monitoring, and forestry management.
Castor's fiber optics products are ideal for LiDAR systems where size and weight are mission critical. Our technology delivers high-quality illumination with low-loss transmission of a Gaussian beam, which can be collimated for long-distance travel. A large collection and transfer efficiency ensure high throughput of back-reflected signals to the receiver. Castor’s designs further reduce noise by mitigating back-reflections, ensuring optimal return loss.
Optimizing Free-space Communication in Challenging Environments
Optical free-space communication transmits an optical signal through an unobstructed medium, typically air or vacuum, without physical cables or fibers. Critical to this technology is relay stations where signals are emitted and collected. Castor offers a range of robust solutions compatible with outdoor use typically encountered at relay stations. Our couplers offer quasi-lossless transmission of a single-mode signal and ensure high-quality illumination even in challenging environments. Combined with the concurrent capacity to detect high-order modes, ranging from a few modes with a photonic lantern to hundreds with a DCFC, light scrambled during its passage through turbid media, such as the atmosphere, can be effectively collected.
