Abstract
An optical scanning apparatus includes: a light source that emits light; a basic wavefront modulator that performs spatial light phase modulation on incident light on an optical path from the light source to an incident end surface of a fiber, to thereby generate light having a basic wavefront and emit the generated light, the light having the basic wavefront being to be incident on the incident end surface for obtaining, by light emitted from an emission end surface of the fiber, illumination light having a basic intensity distribution; and a two-dimensional intensity distribution control apparatus configured to change the basic intensity distribution by emitting light for causing light in which a phase distribution of the basic wavefront is controlled to be incident on the incident end surface of the fiber.
