A time-of-flight, TOF, system (200; 300), comprising: a transmitter (202; 301; 402; 502; 1302) including a plurality of light emitters for transmitting light , the plurality of light emitters including a first group of light emitters for transmitting light with a first field of transmission (406; 506) and a first amount of power per light emitter and a second group of light emitters for transmitting light with a second field of transmission (410; 508) and a second amount of power per light emitter, wherein the first field of transmission at a depth from the transmitter is larger than the second field of transmission at the depth from the transmitter and the first amount of power per light emitter is less than the second amount of power per light emitter; a receiver (208; 302; 1304) to receive reflections of the transmitted light; one or more processors ; and a memory coupled to the one or more processors and including instructions that, when executed by the one or more processors, cause the TOF system to perform operations comprising: determining one or more depths or performing ranging in a scene based on received reflections of transmitted light from the first group of light emitters transmitting in a first mode (404; 608; 802); and determining one or more depths or performing ranging in the scene based on received reflections of transmitted light from the second group of light emitters transmitting in a second mode (408; 610; 804). a transmitter (202; 301; 402; 502; 1302) including a plurality of light emitters for transmitting light , the plurality of light emitters including a first group of light emitters for transmitting light with a first field of transmission (406; 506) and a first amount of power per light emitter and a second group of light emitters for transmitting light with a second field of transmission (410; 508) and a second amount of power per light emitter, wherein the first field of transmission at a depth from the transmitter is larger than the second field of transmission at the depth from the transmitter and the first amount of power per light emitter is less than the second amount of power per light emitter; a receiver (208; 302; 1304) to receive reflections of the transmitted light; one or more processors ; and a memory coupled to the one or more processors and including instructions that, when executed by the one or more processors, cause the TOF system to perform operations comprising: determining one or more depths or performing ranging in a scene based on received reflections of transmitted light from the first group of light emitters transmitting in a first mode (404; 608; 802); and determining one or more depths or performing ranging in the scene based on received reflections of transmitted light from the second group of light emitters transmitting in a second mode (408; 610; 804). determining one or more depths or performing ranging in a scene based on received reflections of transmitted light from the first group of light emitters transmitting in a first mode (404; 608; 802); and determining one or more depths or performing ranging in the scene based on received reflections of transmitted light from the second group of light emitters transmitting in a second mode (408; 610; 804). <EOS>
