Abstract
An apparatus for intraoral imaging has an illumination source that directs light to an object. An imaging apparatus forms an image at an image sensor array from reflected light from the object, the imaging apparatus having an optical stop along an optical axis. A phase modulator is disposed at or near the optical stop. An image processor conditions data from the image sensor array and provides processed image data of the object.
Claims15
An apparatus for intraoral imaging comprising:
- a) an illumination source that directs light to an object;
- b) an imaging apparatus that forms an image at an image sensor array from reflected light from the object, the imaging apparatus having an optical stop along an optical axis;
- c) a phase modulator disposed at or near the optical stop;
- and
- d) an image processor that conditions data from the image sensor array and provides processed image data of the object.

An apparatus for intraoral imaging comprising:
- a) an illumination source that directs light to an object;
- b) an imaging apparatus that forms an image from reflected light from the object at an image sensor array, the imaging apparatus having an optical stop along an optical axis between an objective lens that directs the reflected light through the optical stop and a second lens that directs light from the optical stop to the image sensor array.
- c) a phase modulator disposed at or near the optical stop;
- d) an image processor that is programmed with instructions to condition data from the image sensor array for deblurring according to phase function characteristics of the phase modulator;
- and provides processed image data of the object;
- and
- e) a display in signal communication with the image processor for rendering the processed image data.
