Claim 16:
17. A method of finding a stable time period during acquisition of an optical coherence image, the method comprising:
a. Identifying a region of interest that extends spatially over an array of image pixels;
b. Identifying one or more tested time segments, each tested time segment corresponding to different time-periods of image acquisition in which a number of successive image frames are taken;
c. for each frame within each respective tested time segment, calculating a spatially merged value of detected signals within the region of interest;
d. For each tested time segment, calculating the Fourier Transform of a time series of the spatially merged values to form a power spectrum and extracting one or more stability indicators therefrom;
e. Comparing the one or more stability indicators from each tested time segment and selecting the tested time segment whose stability indicators best match pre-determined criteria; and
f. Identifying the time period of image acquisition of the selected tested time segment as the stable time period.
