Abstract: The radiant energy from a known live source impinges on a radiation collector which in turn directs the energy through a movable slit on to a rotating reticle having alternate reflecting and transmitting segments. A reference source also directs energy on to the reticle and the reticle output is directed toward a sensor whose output is processed by a differential amplifier and a signal amplifier. A reference phase generator circuit controls the gain of the differential amplifier. The output of the signal amplifier is further processed to provide only the low frequencies, which are then amplified and analyzed to provide a scintillation spectrum. A shimmer output is obtained by eliminating the low frequencies and applying the resultant to a limiter and a discriminator. The modulation transfer function is derived by combining, in an operational amplifier, the low-passed frequencies from the signal amplifiers and the peak detected high frequencies.
