CCD Page Reader for Mail-Scanning Applications.

Abstract

The following new design concepts for construction of a high-speed 2200x96-element TDI-CCD line sensor were developed and demonstrated with a 748x96-element page-reader test chip. (1) The four-phase electrode-per-bit clock to improve the vertical resolution of the TDI array by a factor of 1.5 was proposed and designed in the 748x96-element page-reader test chip. (2) To improve horizontal resolution and achieve the required effective output scanning rate of 8.4 x 10 to the 7th power picture elements (PELs) per second. The 748x96-element TDI array with 0.6 mil x 0.6 mil PELs and built with two-level polysilicon buried-channel CCDs can be read out by two types of 4:1 multiplexed outputs. One side of the array can be scanned-out by four parallel output registers with 2.4-mil stages. This mode of operation was experimentally demonstrated. The other side of the array can be scanned-out by two pairs of 2:1 multiplexed output registers with 1.2-mil stages.
