Overlapping Cycles - Single timing

Timing diagrams of overlapping CIC cycles with identical cycle timing definition

This topic describes the behavior of the CIC when it is configured to generate one sequence of 4 cycles, each with identical timings settings.

In the following timing diagrams, user-defined values are shown in red:

c is the minimum cycle period defined by CycleMinimumPeriod,
d is the Strobe delay defined by StrobeDelay,
e is the Camera Trigger pulse width defined by ExposureTime,
r is the minimum time interval between consecutive exposure defined by ExposureRecoveryTime,
s is the Strobe pulse width defined StrobeDuration.

In the following timing diagrams, values calculated by the driver are shown in blue:

a is the CIC cycle duration,
f is the time interval between consecutive Camera Trigger pulses,
the Strobe pulse width. This is the value of StrobeDuration set by the user.

The driver calculates the duration of the CIC Cycle (a value)from the user-defined settings ExposureTime, ExposureRecoveryTime and CycleMinimumPeriod by searching the smallest value satisfying the following conditions:

Condition 1: The time interval between consecutive Camera Trigger pulses (f value) must be greater than or equal to the ExposureRecoveryTime settings (r value). これにより、 Camera Trigger がトリガ伝送リンクを通って確実に流れるようになります。前の露光が完了するまで新しい露光が開始されることはありません。
Condition 2: The CIC Cycle duration (a value) must be big enough to ensure that a new readout doesn't begin before the completion of the previous one.
Condition 3: The CIC Cycle duration (a value) must be big enough to include both transitions of the Camera Trigger and the Strobe signal.

The "Readout-limited" use cases illustrate situations where the cycle period is equal to the duration of the readout phase.

The "Exposure-limited" use cases illustrate situations where the cycle period is equal to the duration of the exposure phase.
