Which optical outcome occurs using lasers to measure distance?

A)Increased coherent interference fringes
B)Minimized chromatic aberration effects
C)Reduced stimulated emission linewidth
D)Magnified diffraction ring separations

💡 Explanation

Laser-based distance ranging relies on coherent waves showing interference. Increased coherent interference fringes appear, because the precisely controlled phase relationship enables accurate distance measurements. Therefore, interference is used, rather than using chromatic aberration mitigation for focusing corrections.
