Abstract :
A novel scanning device utilizing the minority carrier storage effect in a bipolar transistor (MCSD) is presented. MCSD principle operation and imaging application are mentioned. MCSD has a working frequency range that depends on the characteristics of the transistors in use, that is, 0.6 - 10 MHz (life time 7F = 50 nsec) or 0.1 - 0.5 MHz (7F = 600 nsec). The computed working range also shows the essential influence of the time constants of transistors. An integrated MCSD with 64 stages and 64 photo-transistors is discussed.
