Light deflection device with mirror unit and piezoelectric actuators
A recently granted patent (Publication Number: US12007556B2) discloses a light deflection device that includes a mirror unit controlled by two piezoelectric actuators to enable movement around different axes. The device also features a drive unit supplying drive voltages, detection units for monitoring voltage and swing angle fluctuations, and a determination unit to assess the mirror unit's swing state. The determination unit compares detected values with rated values to determine the normalcy of the mirror unit's movement, ensuring optimal performance based on sensitivity equivalent values.
Furthermore, the patent details conditions under which the light deflector operates with varying voltage fluctuation widths, allowing for customizable settings post-startup. The calculation determination unit contrasts sensitivity equivalent values under different conditions to assess the mirror unit's performance accurately. Additionally, the patent addresses potential failure states, such as detecting changes beyond a threshold value in the sensitivity equivalent value, ensuring the reliability and functionality of the swing angle fluctuation width detection unit. Overall, the patented light deflection device offers a sophisticated system for controlling mirror movement, enhancing precision and efficiency in various applications.
