Abstract:
1. A scanning apparatus comprising: a light beam; a multiharmonic oscillator comprising a plurality of connected oscillating sections that resonate at distinct fundamental and harmonic frequencies of each other, including a reflector positioned to intercept the light beam and reflect the light beam from the reflector to an imaging surface; and drive electronics configured to move the multiharmonic oscillator according to a predetermined mathematical series function, thereby causing the light beam to scan the imaging surface as the light beam reflects from the reflector, the mathematical series function including a series of elements, each oscillating section of the multiharmonic oscillator being driven based upon a distinct element of the mathematical series function, the oscillating sections and the drive electronics being configured to move the reflector in a motion that approximates a waveform having a substantially non-uniform angular rate of motion corresponding to a summation of the distinct elements of the mathematical series function.
