Answer:
To assess the level of detector noise in the system
Explanation:
Dark noise is the noise generated in a light sensor photodevice ( such as a
digital imaging receptors) when the photo-cathode is protected from any exterior optical radiation while the device is connected to a power source.
The purpose of any dark noise test is likely to assess the level of detectable noise inbuilt in the system because excessive noise can sometimes reduce the quality of images produced.
