  • Publication number: 20200053270
    Abstract: A visual privacy system unilaterally blocks rolling shutter cameras by providing a periodically interrupted ambient light source imposing bright and dark bands on the image yet at a frequency imperceptible to human observers in the environment. Communication of the modulation pattern to authorized cameras allows unaffected imaging in these regions by authorized individuals. The system also contemplates operation in a barcoding mode with a light modulation providing embedded barcodes that can be extracted from images taken in the region to indicate that the images were improperly acquired and to block the images in certain applications.

  • Publication number: 20200033189
    Abstract: An optical signal analyzing apparatus enables real-time and single-shot analysis simultaneously in both time and frequency domains with spectro-temporal analysis. The apparatus includes a fiber tap coupler for receiving an input optical signal from continuous wave (CW) to ultra-short pulses (femtosecond-picosecond). An optical splitter directs part of the signal to a frequency channel and part to a time channel A photodiode in the time channel directly monitors the intensity evolution and converts it to an electrical signal. In the frequency channel, two sub-channels are provided: one for CW/quasi-CW and one for short-pulse components. A signal processor analyses the time- and frequency-domain data from the time channel and frequency channel and displays the temporal and spectral evolutions simultaneously, so that the two different pieces of information of a non-repeated dynamic event can be correlated in different domains.
