The scale was omitted from Fig. 3 of this Letter.1 It is re­produced correctly below:

Fig. 3. Rise time of two Hughes image transducers as a function of normalized writing irradiance. The full and solid lines are the en­velopes of all measurements made on the two devices. Writing irra­

diance was normalized by the input irradiance which produced saturation.
