“…[13][14][15][16] Recently, correlation-domain LiDAR using continuous light has been proposed, 17) drawing inspiration from a technique referred to as the synthesis of optical coherence functions in fiber-optic sensing. [18][19][20][21][22][23][24] This approach can be implemented through direct modulation, resulting in a costeffective configuration, and boasts the capability of conducting high-speed measurements at arbitrary locations (termed as random accessibility). [25][26][27][28] However, the initial demonstration of correlation-domain LiDAR suffered from the utilization of a 300 m long delay fiber, making the system bulky and necessitating additional efforts in miniaturization and integration for future practical applications.…”
