Image Sensing

The primary functions occurring within a standard image sensor are the conversion of light photons falling onto the image plane into a corresponding spatial distribution of electric charge, the accumulation and storage of this charge at the point of generation, the transfer or readout of this charge, and the conversion of charge to a usable voltage signal. Each of these functions can be accomplished by a variety of approaches, but only the principal sensor types will be considered here. Sensors can be divided into two groups: vacuum tube devices in which the charge readout is accomplished by an electron beam sweeping across the charge in a raster fashion similar to that in a television picture tube, and solid-state devices based on charge-coupled devices or photodiodes. These three types of sensor will be described in the next three sections.

For many years, vacuum tubes provided the only technology available for television applications, and they are still widely used because of the high-quality image signals they provide. On the other hand, the electron beam readout method confers a number of disadvantages, which are not found in solid-state devices, including large size, fragility, susceptibility to shock and vibration, high power consumption and a high degree of sensitivity to external electric and magnetic fields. The principal imaging defects, which again are not present in solid-state devices, include

• lag when displaying changing images, due to slow response speed,

• image burn which is damage to the sensor surface caused by intense light,

• geometric distortion,

• drift in the apparent position of the image,

• a nonlinear relationship between signal output and light intensity which varies with target voltage.
