← ScienceWhich technique exploits optical polarization to allow contrast enhancement?
A)Differential interference contrast microscopy✓
B)Total internal refraction illuminatorscope
C)Bright field transmission illuminationscope
D)Phase contrast transmission microscopy
💡 Explanation
Differential interference contrast (DIC) microscopy enhances contrast because polarized light has its wavefront sheared via Wollaston prisms to create interference patterns; therefore structures appear with enhanced contrast, rather than other techniques that rely on basic absorption.
