  • Patent number: 3931526
    Abstract: A device for measuring transmission factors is comprised of an emitter of light impulses located at a distance from a main photoreceiver. The emitter and the main photoreceiver are optically conjugated by mirrors. An auxiliary photoreceiver located adjacent to the light emitter receives a constant portion of the flux emitted by this emitter and a flux coming from the ambient light. By establishing the ratio between the impulse-type electric signals transmitted by these photoreceivers, a value proportional to the transmission factor measured between the emitter and the main photoreceiver is obtained.
