Definitions

DC source but rather a voltage source.
no means is used to independently adjust the light intensity of each of the three tubes shown, which are all adjusted at the same time by means of a single adjustment source.
FIG. 3 we find the generator 4 already sketched in FIG. 1 and capable of supplying all the tubes at the same time with pulses capable of creating the initiation of the discharge. These pulses appear at terminals S, 0 of generator 4.
FIG. 6 shows a possible embodiment of the blocks 26 and 29 that are found in FIG. 3. It essentially consists of three circuits 555 well known from the state of the art and referenced 40, 41 and 42.
the first circuit 40 is a generator which generates short pulses 50 which are collected on its output 3 and the shape of which is shown in FIG. 7a.
the repetition period T r of the pulses depends on the values given to Ro + R ' o and C o . It can be adjusted by varying R o .
the pulses 50 in turn control the circuit 41 which is a monostable which engages on the falling edge of the pulse 50 and lengthens said pulse by an amount imposed by the values given to R, + R ' i and Ci. It can be adjusted by varying R i .
the embodiment of Figure 6 allows to vary the light intensity by means of a potentiometric adjustment (R 2 ) which is here the setpoint signal itself. It is clear that this adjustment would be carried out in a completely different manner if the reference signal were to be information delivered by a television camera for example.
the camera presents an analog signal at its output which is transformed into a digital signal by a converter.
One then finds at the output of the converter 2 5 32 possible tones corrected according to the formulas (1) and (2) given above, one of these tones corresponding to the light intensity of the point analyzed at a precise moment.
the digital information is then sent to a counter which will output a signal at its output, the duration of which will correspond to the light intensity analyzed at that time. This signal will finally command a holding current source as explained above.
