4 Basic oprating principl / Masurmnt tchniqu xampls Basic oprating principl High sitivity High spd gat opration High-spd gatd ICCD camras ar high-sitivity CCD camras that fatur high-spd gat opration (high shuttr spd). Th imag intifir (or I.I.) coupld to a CCD camra nabls highspd gating along with high-sitivity imaging. ICCD camras can captur itantano action of high-spd phnomna as wll as th faint light that occurs in itantano phnomna. Thy can also offr tim-rsolvd imaging of rproducibl phnomna by programming th gat dlay timing. I.I. ( Imag Intifir) hoto ar convrtd to lctro at th photocathod. Aftr th lctro ar multiplid to svral thoands, th lctro ar convrtd back to photo again. hosphr hotocathod MC scrn Fibr optics MC Channl tructur of MC Incidnt lctron Channl wall VD Output lctro (thoands ti) Amplification of an imag is accomplishd ing an MC built iid th imag intifir (I.I.). Each channl in th MC is a scondary lctron multiplir, multiplying lctro with ach bounc off th channl wall. Gat opration This is a fast shuttr function. This gating which is synchronizd with triggr input can allow to captur fast phnomnon. Oprating principl of gat hotocathod MC hosphr hotocathod MC hosphr scrn scrn hotocathod hosphr MC scrn Fibr optics V - V ynchronizing Gat signal Gat opration is prformd by rvrsing th potntial btwn th photocathod and anod. A high-spd squarwav voltag signal is applid. Th width of this squarwav dtrmi th gat tim (shuttr spd). Masurmnt tchniqu xampls Tim-rsolvd imaging ing sampling mthod Whn masuring rptitiv phnomna, tim-rsolvd imaging can b prformd by shifting th gat dlay timing automatically according to a r-programmd schm. Eliminating background by high-spd gating Whn th targt phnomnon is burid in background light, th gating timing can b synchronizd to match th targt phnomnon to crat clar imags with high signal-to-nois ratio. Capturing fluorscnc (scattring) imags by ing a pulsd lasr This tchniqu capturs fluorscnc imags of sampls of intrst and its cross sction by synchronizing th timing with a pulsd lasr or xcitation light sourc. 4 Capturing high-spd imags of cocutiv fra by DIC mod Dual Imag Captur (DIC) mod can captur coctutiv fra at a μs intrval ing jt on camra. This mod is idal for high-spd imaging of non-rpatabl vnts. This option is availabl on C7--. 4
