Alpha_Peak Valley Detection Principle

The user can change the Peak/Valley detection condition by changing the number of scanning data points, N. If no Peak/Valley is detected within the desired range, it can be solved by adjusting N simply. The tendency to continuously increase (or decrease) can be broken if the scanning interval is too small the difference between two consecutive measured values can become less than photometric repeatability. In this case, no increase (or decrease) group is formed. This can be solved by appropriately setting the measurement scanning interval to a larger value. The difference between two consecutive measured values can be distinguished easily so that the peak can be seen.
