Abstract: The application discloses a food probe comprising an optical rod insertable in a body of food, for example, a roast of meat. At its inner end, the rod is configured to receive and transmit axially through the rod a color image of the food in the area contacted by the end of the rod. The image is transmitted to the outer end, where it is desirably magnified for convenient viewing of internal conditions. If desired, the probe may provide for a plurality of viewing areas, for simultaneously viewing the food at multiple depths. The probe preferably is rigid but may be connected to a flexible fiber optic bundle for viewing at a remote location.
