Pengukuran Jarak pada Rancangan Indirect Time Of Flight (i-ToF) Light Detection and Ranging dengan Sistem Optik Biaksial untuk Kendaraan Otomatis

Abstract

In the development of new technologies, Light Detection and Ranging (LiDAR) is one that can detect, measure and identify distant object. One application of LiDAR is automated vechiles, which can solve transportation problems such as avoiding surrounding obstacles. This research was carried out with a design that uses an infrared laser and photodetector to generated and detect modulated laser signals. With the dual modulation environment used, it can detect amplitude values, phase shift and measured distances. The result show that the research can read high-resolution values for the variety of objects used with the proposed algorithm. The distance measurement results measured with the reference distance have a difference that is not too big, such as aluminium (0,114 m), aluminium foil (0,027 m) and plastic (0,082 m). Measurement errors can be overcome by minimizing errors between the transmitter and receiver. The design can analyze distances up to 56 m on objects made of aluminium foil, 52 m on aluminium and 33 m on objectsmade of plastic. This research is a promising solution for more precise and accurate distance measurements.
