iii1'DElectronic Circuit for DeterminingRotation TimeThe implemented oscillator in the electronic circuit defines the time base. The rotatingtwo diodes and the time that this takes is stored by usinglaser beam hits thethe time base of the oscillator. The measuredtime can then be read out by the parallel port using the data bits and three different registers. The completeelectronic circuit can be seen in Figure D.I."1Jla Jo l_^|1 I 1I11Jü4ju 1 ü_ri_1 1 L1 HJ1| 1 1 1 1 1 1 1 1 1 1 | 1 1 1 1 1* L1 l Li, M M 1 II II—i
