Multi-Wavelength Spot-Array Beams Based on Tunable Dammann Grating Metasurface
The structured light projection (SLP) method occupies a crucial position in three-dimensional (3D) imaging technology. Different working wavelengths of structured light can be employed depending on the situation. However, there are few structured lights that can be modulated based on wavelength at p...
