Detailed Description

Trigger parameters.

Used for triggering camera and light source (mostly a double-cavity Nd/YAGG laser) and defining separation time between the frames of a PIV image pair etc. The parameters might be loaded from the configuration resources, with gpiv_scan_resourcefiles() or with gpiv_scan_parameter().
