The EM-CCD is essentially an image sensor that can identify and quantify single photon events without the use of an image intensifier. This is made feasible by the chip’s distinctive electron multiplication structure.
To combine high sensitivity with rapid speed, EM-CCD cameras overcome a basic physical limitation. Traditional CCD cameras had a slow readout speed that prevented them from having high sensitivity to readout noises.
As a result, they were frequently called “slow scan” cameras. The CCD charge amplifier was the primary restraint. The charge amplifier’s bandwidth must be as broad as feasible in order to operate at a high speed, but since noise increases with amplifier speed, higher-speed amplifiers also have greater noise levels.
Slow-scan CCDs can only be read out at slow speeds, usually less than 1MHz, because of their comparatively small bandwidth.
By boosting the charge signal before to the charge amplifier, EM-CCD cameras get around this restriction and can achieve previously unheard-of sensitivity at fast speeds.
The readout noise, which often places a limit on the sensitivity in CCD and CMOS, is successfully overcome when the signal is amplified before reading.
The majority of EM-CCDs employ a Frame Transfer CCD construction as well. The standard sensor’s “image portion,” which captures the image, and a second “storage area,” where the image is stored until being read out, are both present in Frame Transfer CCDs.
An opaque mask, often formed of aluminum, is used to cover the storage space, which is typically the same size as the sensor area. The sensor area is exposed to the light signal during an acquisition, capturing an image.
This image is then automatically relocated lower beneath the chip’s masked section and read out. The sensor area is prepared to gather the signal for the following image while this is taking place.
