- Do I need a shutter on my CCD camera?
A shutter is required when using a full frame CCD's such the Kodak KAF series. Otherwise, light falling on the CCD array following an exposure will cause smearing in the image. Interline CCD's such as the Kodak KAI371 have a "digital" shutter that can shift the image to a protected area in about 50,000th of a second. Some type of shutter is required for lunar and planetary work.
- How important is cooling?
Cooling is extremely important to minimize noise due to dark current growth in the CCD. All CCD's experience gradual filling of the individual pixel cells due to dark current infusion. The rate of dark current growth is related to the temperature of the CCD and roughly doubles every 6 degrees C. CCD cameras with undersized heat sinks and/or simple single stage cooling are unlikely to maintain a stable temperature below -5 C when the ambient air temperature is 20-25 C. Regardless of quantum efficiency, these camera's will perform poorly with long timed exposures of faint objects. A well designed camera with a proper size heat sink, properly mounted low vibration fan and a dual stage TEC will easily maintain a temperature of -30 C, lowering the dark current by a factor of 16 times (4 times less noise. Another important factor is the ability of the the camera to return exactly to the same temperature settings at some future date so that ones research is reproducible.
- How important is a low noise in a CCD camera design?
Low noise is important in resolving fine detail. Electronic noise is always present and "creeps" into the system while measuring the individual pixels during the CCD readout phase. Electronic noise can be minimized by using double correlated sampling or dual slope integration techniques. The best cameras utilize dual slope integration when measuring the value of each pixel element during the CCD readout phase. This is analogous to properly "zeroing" your measuring device each time before measuring the next pixel. Properly designed electronics which incorporate dual slope integration elements will certainly out perform simple sample & hold based correlated double sampling designs when digitizing to 16-bits.
