E. Fortunato et al., PERFORMANCES PRESENTED BY LARGE-AREA THIN-FILM POSITION-SENSITIVE DETECTORS BASED ON AMORPHOUS-SILICON, Thin solid films, 272(1), 1996, pp. 148-156
This paper presents a low-cost technology for the realisation of large
-area thin film position-sensitive detectors using the a-Si:H technolo
gy. The obtained results are quite promising regarding the application
of these sensors to a wide variety of optical inspection systems, suc
h as: machine tool alignment and control; angle measuring; rotation mo
nitoring; surface profiling; medical instrumentation; targeting; remot
e optical alignment; guidance systems; etc., to which automated inspec
tion control is needed.
