Flash-Continuous mode of Spectral Aquisition

Flash-continuous cycle is an extension of Continuous cycle that adds control over Exposure Shutter. This is a composite mode that synchronizes exposure and data acquisition in a flexible cycle.

Structure

Data acquisition part of the cycle is mostly identical to that described in Continuous acquisition mode.  The main distinction is that in some shutter modes data acquisition is suspended until or synchronized to the closing of Exposure Shutter.

Shutter part of Flash-continuous mode is always synchronized to acquisition at the start of Shutter operation. In some Shutter modes the end of exposure is synchronized as well, while in others Shutter operation is independent from acquisition once exposure has started. Shutter event can occur once per acquisition or triggered every cycle, in both cases after skipping specified number of cycles.

Time

Time dimension of acquired data and total duration of acquisition are defined in real elapsed time, just as in Continuous acquisition. Shutter operation has no direct influence on time calibration, other than synchronized acquisition cycle may be longer depending on Shutter settings.  Like in Continuous mode, Flash-continuous acquisition can run indefinitely if total duration is set to a negative value. 

Parameters

Timing parameters of acquisition and Shutter parts of Flash-continuous cycle are controlled independently. Both parts may involve dynamic parameters such as progressive change in Integration or Shutter duration from one cycle to the next.

Hardware

Flash continuous cycle is not available if shutter controller is not present.

Data flow

Processing, Destination, and Display options are identical to Continuous cycle.
