Which limitation arises when multiple independent lasers illuminate a holographic projection surface?

💡 Explanation

Speckle patterns reduce image clarity because each laser's slightly different path length creates random interference, a loss of coherence; therefore, combined coherent beams produce grainy artifacts rather than uniform illumination like a single coherent source and predictable interference.
