Q1, Q2 constitute of two class transistor amplifiers and used as zooming the modulating output semaphore of silicon solar battery. To 5lm/ft2 (lft=30.48 cms) beam of light modulated by 1000HZ, when the R is requlated to the biggest gain, the circuitry will produce 1V virtual value of voltage in output port. Thiscircuitry issuitable foroptics correspondence andwarning system.
