Introduction Each MOVISTROB® product has to pass through various controls during its production phases and must also undergo very strict and conscientious function and quality tests before leaving the factory for delivery to our clients. We can assure you that the MOVISTROB® product you received is in strict conformity with our high quality standards and it fully meets all safety and performance requirements. All relevant data on this instrument are electronically stored and can be recalled...

The instrument carries the following controls and functional components (see fig.):3.1SIGNAL MAINS PUSHBUTTON ( 1 ) switches on the instrument by depressing the pustbutton.Red signal appears when ready to work.3.2SIGNAL FLASH FREQUENCY RANGE SELECTOR PUSHBOTTON ( 3 ) for selection of desired flash range:Push ButtonFlashes/Min = RPM Flashes/Sec = Hz Low range (grey signal indicated) 150 - 4000 2.5 - 66.67 High range (red signal indicated) 3700 - 18000 61.67 - 300. > (overlapping ranges) 3.3CONTROL KNOB with DIAL ( 4 ) for continuous adjustment of flash frequency within the range selected by the...

(5) > (does not apply for models 350.00 and 300.00) The BNC-Outlet is placed next to the input for external control (5) .The pulse voltage is between 5 to 10 V making an average of 7 V.The impedance does not exceed 10 K Ω .3.7MODE SWITCH EXT / INT for SELECTION of INTERNAL or EXTERNAL CONTROL (7) serves to select the desired mode of synchronization.The switch has to be set on position "EXT" when the flash frequency is to be controlled by anexternal source via "Trigger Input (6) ".On position "INT" the flash rate can be adjusted by means of Control Knob with Dial (4) withinthe selected range 4....

To measure the RPM v either the highest flash frequency f1 = v which results in a stopped image of the objectcan be determined, or two neighbouring flash frequencies fn and fn+1 can be determined and from thesethe rotational frequency computed. For the periods for f and fn+1 in the flash frequency the equation is: r = Tn+1 - Tn From this we derive the frequencies: v = fn > ՕՕ fn+1 緷 fn - fn+1 5.3Slow-Motion Cycle If the period T of the flash frequency deviates slightly from a whole-number multiple Tn = nr of the rotationtime r of the object, i.e. T = (n + e) r with /e/ < 1 then the object no...

k with increasing n . The interval in whichthe mark is illuminated at one corner of the k -angle amounts to n rotation periods. In conclusion , the k markimages must not overlap. Altogether we may expect observable images only with low values of n and k .In objects with a complicated texture the phantom objects mostly disappear in an untextured background.5.5Objects with a Finite Rotational Symmetry In many cases the axis of the rotating object is an m -number symmetrical axis, i.e. the object overlaps itselfthrough a rotation about the angle 2/m . In the example of the disc this is achieved...
