Time of flight-based systems operable for ambient light and distance or proximity measurements

A time-of-flight-based optoelectronic system comprising:

• at least one active demodulation detection pixel operable to detect a first particular wavelength, and being further operable to generate amplitude data of the first particular wavelength;
• at least one spurious reflection detection pixel operable to detect a second particular wavelength, and being further operable to generate amplitude data of the second particular wavelength;
• outputs of the at least one active demodulation detection pixel and the at least one spurious reflection detection pixel being communicatively coupled to a computational device;
• the computational device including a computer storage medium storing spectrum data that corresponds, respectively, to a plurality of different ambient light source types, wherein the amplitude data of the first particular wavelength and the amplitude data of the second particular wavelength are associated with spectrum data of a particular one of the ambient light source types,
• wherein the computational device is operable to identify the particular one of the ambient light source types based on a ratio of the amplitude data of the first and second particular wavelengths and based on the stored spectrum data.
