t1 is the max. time after a high signal on the synch. input of S1 until the analog value will be held. This value
will be held as long the signal on the synch. input is high.
The min. time between the high signal of S1 and the low signal of S2 is t1, also. In this case, an optical
influence between the sensors is not possible.
t2 is the time until the analog signal is ready after a low signal on the synch. input of S2. This time depends
on the reflectivity of the object and if the reflectivity changes during the hold time.
