摘要： The present invention relates to a device for classifying a light source, comprising: a sensor adapted to receive a luminous flux emitted by a light source, the sensor comprising a plurality of pixels grouped in sets, each set comprising a first pixel and a second pixel adjacent to the first pixel, each first pixel being adapted to generate a first signal relating to a first portion of luminous flux in a first spectral band received by said first pixel, each second pixel being adapted to generate a second signal relating to a second portion of luminous flux in a second spectral band received by said second pixel, a computer configured to compare the first and second signals and to classify the emitting light source according to the result of the comparison.

摘要： The present invention relates to an optical pulse detection device, the device comprising a sensor having a plurality of pixels, each pixel comprising: a receiver configured to receive optical pulses and generate an electrical signal, an event detection unit comprising a frequency filter having an adjustable cut-off frequency defining a passband for the event detection unit, the adjustable cut-off frequency being such that the upper bound of the passband is greater than or equal to 1 Megahertz, the detection unit being configured to detect variations in the electrical signal generated by the receiver only when the frequency in the frequency domain of said variations is within the passband of the event detection unit, and a timing unit configured to date each change in the electrical signal detected by the event detection unit.
