Abstract
An apparatus for producing a hologram of an object includes a light source that emits an incoherent electromagnetic wave toward the object, and a masking device configured to display a mask, receive the incoherent electromagnetic wave emitted toward the object, mask the received incoherent electromagnetic wave according to the displayed mask, and produce a masked electromagnetic wave. The apparatus also includes an image recording device configured to capture an image of the masked electromagnetic wave, and a processing device configured to convert the image of the masked electromagnetic wave into the hologram of the object. A method for producing a hologram of an object is also described.
Claims16
An apparatus for producing a hologram of an object, the apparatus comprising:
- a light source that emits an incoherent electromagnetic wave toward the object;
- a masking device configured to display a mask, receive the incoherent electromagnetic wave emitted toward the object, mask the received incoherent electromagnetic wave according to the displayed mask, and produce a masked electromagnetic wave;
- an image recording device configured to capture an image of the masked electromagnetic wave;
- and
- a first hologram calculating section configured to calculate the hologram of the object based on the image of the masked electromagnetic wave captured by the image recording device.
A method for producing a hologram of an object, the method comprising:
- emitting an incoherent electromagnetic wave toward the object;
- displaying a displayed mask;
- receiving the incoherent electromagnetic wave emitted toward the object;
- masking the received incoherent electromagnetic wave according to the displayed mask to produce a masked electromagnetic wave;
- capturing an image of the masked electromagnetic wave;
- and
- calculating the hologram of the object based on the image of the masked electromagnetic wave captured by the capturing.
