Dual optical mapping apparatus based on two CMOS from SciMedia. A photograph of a dual mapping system based on two CMOS cameras has general features similar to those shown in Figure 12.17.1, except for the dimensions of the CMOS compared to the PDAs, which require changes in the lenses used to focus the excitation beam and to focus images of the heart on the smaller CMOS sensors (1 × 1 cm2) compared to the larger PDA sensing surface (1.8 × 1.8 cm2).
