60mm方形CCD，不是CMOS喔。 a 4096(H) x 4096(V) solid state Charge Coupled Device (CCD) Full Frame sensor. The CCD is intended for advanced scientific, space, industrial, and commercial digital imaging applications. The CCD6161 active area is organized as an array of 4096 horizontal by 4096 vertical imaging elements. In addition to 4096(H) x 4096(V) imaging elements there are 8 peripheral columns on left and right edges of the imaging area to improve non-uniformity at t h e edges. These 16 peripheral columns are not connected to t h e serial register. There are 32 isolation rows on top and bottom of the imaging area and these 64 isolation rows are covered by metal, making the total array 4112(H) x 4160(V). The pixel pitch is 15µm with a 100% fill factor. For dark reference, each readout line is preceded by 18 dark pixels. A split readout architecture has been adopted to facilitate high data rates with simultaneous readout from four output ports, and provides the flexibility to read out the entire image frame from two output ports, or from a single output port to simplify the drive electronics requirements.
