Abstract: A buffer arrangement for providing pixel information in a Lissajous scanning projection system is provided. The projection system includes a memory, a MEMS mirror, a projection unit, and a data unit. The memory includes a projection buffer and a shadow buffer. An incoming stream of pixel information scanned from the MEMS mirror is written to the shadow buffer. The incoming stream of pixel information is forwarded to the projection buffer. The projection buffer forwards the incoming stream of pixel information to the projection unit. The projection unit projects the incoming stream of pixel information based on the Lissajous pattern through a mirror projector trajectory. The shadow buffer and the projection buffer operate at different frequencies.

Abstract: The present disclosure provides a Lissajous dual-axial scan component (100) that includes an outer frame (102), a first pair of supports (104A-B), a second pair of supports (106A-B), an inner frame (108), a mirror (110), a sensing arrangement (112), a controller (114) and a memory (116). The memory (116) stores multiple tuples each including a first-axial bias frequency value, a second-axial bias frequency value, and a phase difference between actual driving frequencies (i.e. a first-axial bias frequency and a second-axial bias frequency) of the mirror (110). The controller (114) is coupled to the sensing arrangement (112) to receive signals indicative of current resonant frequencies of the mirror (110) and configured to select one of the tuples from the memory (116) based on the signals received from the sensing arrangement (112) and set the applied bias frequencies, and their phase difference, according to the selected tuple.
