Claim 18:
19. A scanning method of an optical sensing system to capture a frame, comprising:
emitting light towards an environment;
causing a Hadamard mask to resonate, the Hadamard mask comprising a frame beginning pattern and a coded pattern;
identifying a start signal indicating a beginning of the frame at a new scanning angle when the light reflected from the environment passes through the frame beginning pattern of the Hadamard mask aligned with a slit of a slit apparatus;
detecting, by a photodetector array, the light reflected from the environment that passes through each of a plurality of rows in the coded pattern of the Hadamard mask aligned with the slit of the slit apparatus after the frame beginning pattern in a sequential manner; and
generating the frame based on the sequentially detected light.
