System and method for designing a scanning mirror assembly with an optimized frequency bandwidth based on spring constant information

An apparatus for designing a scanning mirror assembly for an optical sensing system, comprising:

• a communication interface configured to receive an initial set of design parameters of the scanning mirror assembly;
• a memory configured to store a computer model configured to simulate scanning mirror oscillation;
• and

• simulate first scanning mirror oscillation based on the initial set of design parameters using the computer model to compute an initial non-linear spring constant associated with at least one spring of the scanning mirror assembly;
• adjust the initial set of design parameters for the scanning mirror assembly based on a comparison between the initial non-linear spring constant and a target non-linear spring constant, the adjusted set of design parameters including at least one structural alteration to the at least one spring;
• and
• output the at least one structural alteration to be implemented on the at least one spring,
• wherein the initial set of design parameters and the adjusted set of design parameters are associated with a same mirror oscillation frequency and linear spring constant.
