TH 7895M-(H)

TIMING DIAGRAM

Device operation generally begins with a «cleaning» period, which consists in transferring and eliminating all charges created

by thermal generation. Once emptied, each pixel can accumulate charges in proportion to incident light during the integration

(exposure) period.

After that time, no luminous event must reach the image zone, in order to prevent smearing effects during the image readout

period. This condition can be achieved by using a shutter, gated intensifier or strobe (as an example) to ensure that no light

is collected during the readout period. The 516 lines are then transferred, line by line, into the output register. The total

number of transfer periods is at least 516.

Note 1 : During cleaning period it is possible to transfer several lines in the output register. This is achieved by running Φ while

Note 1 : being in accumulation mode on the output register. This will improve time cleaning of the image zone. The number of

of the output register.
