Claim 0:
1. A receiver of an optical sensing system, comprising:
a slit apparatus;
a Hadamard mask configured to resonate during a scanning procedure performed by the optical sensing system, the Hadamard mask comprising:
a frame beginning pattern configured to be aligned with a slit of the slit apparatus to identify a start of a frame at a new scanning angle captured during the scanning procedure; and
a coded pattern configured to be aligned with the slit of the slit apparatus after the frame beginning pattern to provide sub-pixelization of the frame at said scanning angle; and

a photodetector array positioned on a first side of the Hadamard mask opposite to the slit apparatus, the photodetector array configured to detect light that passes through the Hadamard mask during the scanning procedure to generate the frame.
