The TSLW1401 linear sensor array consists of a 128
脳
1 array of photodiodes, associated charge amplifier
circuitry, and a pixel data-hold function that provides simultaneous-integration start and stop times for all pixels.
The pixels measure 63.5
碌m
(H) by 55.5
碌m
(W) with 63.5-碌m center-to-center spacing and 8-碌m spacing
between pixels. Operation is simplified by internal control logic that requires only a serial-input (SI) signal and
a clock.
