   Is an output signal of ST-402 proportional to incoming light power? I would like to make sure that ST-402 is calibrated to be linear to incident light power.

   Yes, ST-402 cameras are highly linear, until saturation of course. You can validate this for yourself by taking a series of progressively longer exposures of a constant source.
