We demonstrate the dynamic OCT analysis of mental sweating of a few tens of eccrine sweat glands on a human fingertip. We propose a novel method for evaluation of the amount of excess sweat in response to mental stress, where the en-face OCT images of the spiral lumen of the eccrine sweat gland are constructed by data acquisition of the 128 B-mode OCT images. The dynamic analysis of mental sweating is performed by the time-sequential piled-up en-face OCT images with the frame spacing of 3.3 sec. Strong non-uniformity is observed in mental sweating where the amount of excess sweat in response to sound stress and physical stress is different for each sweat gland.
