Low light level photoreceptor

A circuit layout for generating an electrical signal responsive to reception of light energy comprises a first photoelement pair (40 and 102) having first and second photoreceptors (34) and first operation circuitry fabricated between the first and second photoreceptors, the first operation circuitry including a first read line (44) and a first switching means (48 and 90) for connecting a single photoreceptor of the first and second photoreceptors to the first read line at a given time; a second photoelement pair having third and fourth photoreceptors and second operation circuitry fabricated therebetween, the second operation circuitry including a second read line electrically connected to the first read line and including a second switching means for connecting a single photoreceptor of the third and fourth photoreceptors at a given time; and a transfer amplifier (46) electrically connected to the first and second read lines to receive signals for transfer to processing circuitry.
