Description
The TSL201R linear sensor array consists of a 64
脳
1 array of photodiodes and associated charge amplifier
circuitry. The pixels measure 120
碌m
(H) by 70
碌m
(W) with 125-碌m center-to-center spacing and 55-碌m
spacing between pixels. Operation is simplified by internal control logic that requires only a serial-input (SI)
signal and a clock.
The TSL201R is intended for use in a wide variety of applications including mark detection and code reading,
optical character recognition (OCR) and contact imaging, edge detection and positioning as well as optical linear
and rotary encoding.
