A frame transfer CCD solves both problems: it has a protected, not light sensitive, area containing as lots of cells as the area exposed to light. Typically, this location is covered by a reflective material such as aluminium.</p>

<p class="p__1">When the direct exposure time is up, the cells are transferred extremely rapidly to the hidden location. At the exact same time, the exposed part of the CCD is gathering light again, so no hold-up takes place in between succeeding direct exposures. https://www.ccd-detector.com of such a CCD is the greater expense: the cell location is<br>essentially doubled, and more intricate control electronics are needed. Intensified charge-coupled device [edit] A magnified charge-coupled device (ICCD)is a CCD that is optically linked to an image intensifier that is mounted in front of the CCD. These three aspects are installed one close behind the other in the pointed out series. The photons which are originating from the source of light fall onto the photocathode, consequently creating photoelectrons.</p>

<p class="p__2">The photoelectrons are sped up towards the MCP by an electrical control voltage, used between photocathode and MCP. The electrons are increased inside of the MCP and afterwards accelerated towards the phosphor screen. An image intensifier naturally includes a shutter functionality: If the control voltage between the photocathode and the MCP is reversed, the released photoelectrons are not accelerated towards the MCP but return to the photocathode. Thus, no electrons are increased and emitted by the MCP, no electrons are going to the phosphor screen and no light is given off from the image intensifier.</p>
