Apparatus and method for recording fresnel holograms

摘要

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.

1. An apparatus for producing a hologram of an object, the apparatus comprising:
a source that emits an incoherent electromagnetic wave that illuminates the object; a masking device configured to display a mask, receive an incoherent electromagnetic wave transmitted by 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 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.
