Claims18
A manufacturing method of a first optical element applied to a miniature microscope, comprising the steps of:
- emitting a signal light and a first reference light to an optical material;
- forming a plurality of gratings on the optical material by interfering the signal light and the first reference light;
- and
- emitting an object light and a second reference light through the first optical element to form a light field interference distribution;
- wherein an image-capturing element receives the light field interference distribution to generate an image signal;
- wherein a calculating element receives the image signal and calculates according to the image signal to produce a display signal;
- and
- wherein a display element receives the display signal to display an image of an object.
