linear CCD TCD1201d readout and timing issue

im extremly sceptical, i had to put 3 layer of eletricaltape and the sensor was still sensible to ambient light and going in saturation when using the 5w classic red laser...

I guess you can decrease the integration time as it seems the integration is the time of the previus reading, so if you do a reading without ADC the next one may be less sensible

so, cover that sensor as much as possible and then shine a laser/light on it
