Abstract Time-of-flight (TOF) measurement of femtosecond light pulses was investigated for
laser ranging of long distances with sub-micrometer precision in the air. The bandwidth …

Strong ultraviolet electroluminescence with an external quantum efficiency above 1% is
observed from an indium-tin oxide/SiO 2: Gd∕ Si metal–oxide–semiconductor structure. The …

Aiming at coherence degradation during target detection, a suppressing method based on
frequency-modulated continuous wave coherent lidar is proposed. Combined with a random …
