because of low sensitivity of this CCD, I have some restriction about using optical system (mirrors and lens to focus light on CCD) with typical light source (such as typical lamp) which haven't sufficient intensity.
Do you say that I can't see some non-noisy digital output of a bare CCD...
Thanks. According to the CCD's data sheet, response or sensitivity of this sensor isn't high.
Perhaps it needs some special optical system and a source with high intensity
such as xenon lamp (which used in scanners) to get better results.
I have another related problem:
My work is based on...
Hi,
I have an experiment with this CCD in which
When the light sorce is so near to CCD, It indicates some output voltage on oscilloscope screen according to intensity of light on it's pixels. However, by moving the sorce light far from CCD, the output will equal to zero (i.e. dark ).
I want to...
Thaks for your answer.
But i have the most problem with the distance between light source and CCD sensor. One of my CCD (a linear colored CCD used in scanner)
, despite the other one (used in camera),
responds when the light sorce is so near to it
but it doesn't respond by moving the light...
What are differences between CCDs used in scanners and CCDs used in cameras? Do they have different sensitivity to light?
I have two electrical circuit for a CCD sensor used in scanner and a CCD sensor used in camera. the latest works even for lights far from the sensor, but the formest works...
