hi,
im working on a project which involves image aqusition from a gray
scale image sensor. (KAC - 9630). the aqured image is at a distance of
5 inches from the sensor and is flat. for best results i need a way to
make the illumination level on the surface constant, uniform and very
high. i've tried white LED illumination, but could not get a uniform
field. therefore im planning to use a flasher of a normal camera for
this. Problems im having are:
is it possible to continuously power a flasher. if yes, what might be
the powrer consumption?
how do i power a flasher. do i need specialy circuits for that? if
yes, where can i get some sample circuits?
if continuous powereing is not possible, will it be possible to turn
it on just before the image is taken. the image rate of the sensor is
580 frames/sec.
are there any alternatives to this scheam?
thank you.
