Abstract: Example phototherapy systems, methods of using a phototherapy system, and methods of manufacturing a phototherapy system are described. An example phototherapy system includes a handle and a phototherapy light source. The phototherapy light source is attached to the handle, adapted to emit a light in a therapeutic wavelength, and includes a plasma lamp. The plasma lamp can be disposed between sheets of transparent material, including quartz. The phototherapy light source can be adapted to emit a light in a UVB wavelength between about 300 nanometers and about 320 nanometers and can have an output of between about 15 mW/cm2 and about 21 mW/cm2.

Abstract: A pixel readout circuit including at least first, second and third memory locations. During an integration period of a pixel, the pixel readout circuit repeatedly samples the pixel output level during the integration period, stores the first sample in the first memory location, and stores each subsequent sample in memory locations other than the first memory location. Each sample is stored with a time corresponding to when that sample was taken, such that at any one time subsequent to the first three samples having been stored, at least the first sample and the two most recent samples are stored. Also disclosed is a corresponding method of reading out of a pixel output over an undefined integration period.
