  • Real Time Eye Detector with Cascaded Convolutional

    A light detector (your eye) has an area of 2.00 x 10-6 m2 and absorbs 80% of the incident light, which is at wavelength 500 nm. The detector faces an isotropic source, 3.00 m from the source. If the detector absorbs photons at the rate of exactly 4.000s-1 at what power does the emitter emit light?

    Light detectors are designed to convert low light levels into an electric signal of reasonable amplitude to avoid deterioration of the signal by external noise or pick-up. To ensure a high-quality signal, a light detector must fulfill three main requirements: • A high quantum efficiency to transfer as many of the photons as possible into charge carriers to ensure a high signal amplitude. The ...

If n = 1.5 for air and glass, then r = 4% for each surface. Two filters separated by air transmit 8% less than two connected by optical cement (or even water).
