Various techniques are employed for precise optical alignment in nanotechnology:
Interferometry: Utilizes the principle of interference to measure small displacements and align optical components with high precision. Laser Alignment: Involves the use of laser beams to align optical elements. This method is particularly useful due to the coherence and collimation properties of laser light. Micromanipulators: Enable fine control over the position of optical components, often with resolutions in the nanometer range. Feedback Systems: Use real-time data to continuously adjust the alignment of optical components, ensuring optimal performance over time.
