Abstract
Among other aspects, various embodiments include encoding wavelength-based characteristics, in addition to three-dimensional positions, of a plurality of objects of a plurality of different wavelengths directly in an image of the objects.
Claims8
A light-field microscopic apparatus comprising:
- optics configured and arranged in an optical path, wherein the optics and the optical path are configured and arranged to pass light for tilted illumination of an object and to modify a shape of light, wherein the illumination is tilted at an acute angle relative to a focal plane of the object and while being illuminated light is emitted from the object, and
- circuitry configured and arranged to respond to the light emitted from the object by generating a three-dimensional image from the light and by using the modified shape to provide depth-based characteristics of the object.
