  7. The V1 — V2 switch is made by sending a frame synchronized code 1010 to the 1216 controller during the last prep frame. It has been brought to our attention that the PAR OMA-2 offers a differential voltage readout in the extended-delay time mode (timing mode 4). However, since the filament is temporarily turned off, this mode is not useful for pulsed illumination sources at room temperature. The authors have designed and tested a simple electronic circuit to allow V1 - V2 switching at the completion of the prep frames (manuscript in preparation).

Fig. 1

Vidicon linearity (ordinate corrected for background) at a fixed prepared cathode voltage and various reading cathode voltages. The rms noise in background is 0.72 (V2 = 5.0 V), 1.0 (V2 = 5.5 V), 2.3 (V2 = 6.0 V), 4.5 (V2 = 6.5 V), and 17.5 counts (V2 = 7.0 V). Scan parameters: prep frames = 15, channel time = 80 μsec, channel integration = lø = 150, AX = 200, Y ø = 200, and AY = 100; counts are per channel, full photocathode illumination.
