Patent ID: 11874454
Assignee: EVIDENT CORPORATION
Field: Optics (Instruments)
Classification: CPC G  A | IPC A  G

Claim 5:
6. The optical scanning apparatus according to claim 1,
wherein the basic wavefront modulator comprises:
a first basic wavefront modulator configured to perform spatial light phase modulation on the light emitted from the light source, such that the light to be incident on the first end surface of the fiber has a first basic wavefront and is transmitted by the fiber to exit from the second end surface of the fiber as first illumination light having a basic intensity distribution in a first region with a first predetermined distance from the second end surface of the fiber; and
a second basic wavefront modulator configured to perform spatial light phase modulation on the light emitted from the light source, such that the light to be incident on the first end surface of the fiber has a second basic wavefront and is transmitted by the fiber to exit from the second end surface of the fiber as second illumination light having a basic intensity distribution in a second region with a second predetermined distance from the second end surface of the fiber, and

wherein the optical scanning apparatus further comprises an optical system configured to cause the light having the first basic wavefront and the light having the second basic wavefront to be incident on the two-dimensional intensity distribution control apparatus while switching between the light having the first basic wavefront and the light having the second basic wavefront.
