LISSAJOUS DUAL-AXIAL SCAN COMPONENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18196773 titled 'LISSAJOUS DUAL-AXIAL SCAN COMPONENT
Simplified Explanation
- The patent application describes a Lissajous dual-axial scan component. - The component includes an outer frame, pairs of supports, an inner frame, a mirror, a sensing arrangement, a controller, and a memory. - The memory stores multiple tuples, each containing values for first-axial bias frequency, second-axial bias frequency, and phase difference between actual driving frequencies of the mirror. - The controller receives signals from the sensing arrangement indicating current resonant frequencies of the mirror. - Based on these signals, the controller selects a tuple from the memory and sets the applied bias frequencies and their phase difference according to the selected tuple.
Original Abstract Submitted
The present disclosure provides a Lissajous dual-axial scan component () that includes an outer frame (), a first pair of supports (A-B), a second pair of supports (A-B), an inner frame (), a mirror (), a sensing arrangement (), a controller () and a memory (). The memory () 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 (). The controller () is coupled to the sensing arrangement () to receive signals indicative of current resonant frequencies of the mirror () and configured to select one of the tuples from the memory () based on the signals received from the sensing arrangement () and set the applied bias frequencies, and their phase difference, according to the selected tuple.
