Abstract
A digital holographic microscope that includes a light source and a photonic integrated circuit. The photonic integrated circuit can include a branching waveguide optically coupled to the light source, and a multi-angle illumination device optically coupled to the branching waveguide. In various examples, the multi-angle illumination device includes an optical phased array that includes a plurality of light emitters. In various examples, the multi-angle illumination device includes a grating coupler.
Claims20
A digital holographic microscope comprising:
- a light source;
- and
- a photonic integrated circuit comprising:
- a branching waveguide optically coupled to the light source;
- and
- a multi-angle illumination device optically coupled to the branching waveguide.
A method of creating a digital holographic image, the method comprising:
- (i) splitting a light beam into a plurality of light beams;
- (ii) shifting a phase of at least one of the plurality of light beams;
- (iii) combining the plurality of light beams to create a superposed light beam;
- (iv) illuminating an object to be imaged with the superposed light beam;
- and
- (v) receiving the superposed light beam with an imager.
A method of creating a digital holographic image, the method comprising:
- (i) splitting a light beam into a plurality of light beams;
- (ii) refracting only one of the plurality of light beams through a lens;
- (iii) guiding the refracted beam to a grating coupler,
- (iv) illuminating an object to be imaged with the light emitted by the grating coupler;
- and
- (v) receiving the light emitted by the grating coupler with an imager.
