Distance detecting systems for use in automotive applications including gallium and nitrogen containing laser diodes

A distance detecting system for use in an automotive applications, comprising:

• a power source;
• a processor coupled to the power source and configured to supply power and generate driving currents;
• one or more gallium and nitrogen containing laser diodes disposed within an automotive light, the one or more gallium and nitrogen containing laser diodes configured to be driven by a driving current from the processor to emit a first light with a first peak wavelength;
• a wavelength conversion member configured to receive at least partially the first light to reemit a second light with a second peak wavelength that is longer than the first peak wavelength and to combine a portion of the first light with the second light to produce a white light;
• one or more first optical elements coupled to the wavelength conversion member to receive the white light to generate an illumination source further comprising a first sensing light signal based on one of the first peak wavelength and the second peak wavelength;
• and
• a detector configured to detect reflected signals of the sensing light signal to determine coordinates of the at least one remote point of the one or more target objects and their surroundings.
