Abstract:
A multicolor sensor comprising:a transparent first conductive layer at a light-incidence side of a stack;first layer sequence adjacent said first conductive layer and following said first conductive layer in a direction of travel of light through said stack, said first layer sequence forming part of said stack and constituting a first diode function absorptive to a low wavelength in said light;a transparent second conductive layer adjacent said first, layer sequence;a second layer sequence adjacent said second conductive layer and following said second conductive layer in said direction of travel, said second layer sequence forming part of said stack and constituting a second diode function absorptive to an intermediate wavelength in said light greater than said low wavelength;a transparent third conductive layer adjacent said second layer sequence;a third layer sequence adjacent said third conductive layer and following said third conductive layer in said direction of travel, said third layer sequence forming part of said stack and constituting a third diode function absorptive to a wavelength in said light greater than said intermediate wavelength; anda fourth conductive layer adjacent said third layer sequence whereby a three-color signal is obtainable simultaneously from said conductive layers.
