Compact and stand alone holographic device using mobile phone, tablet, or computer screen

A method of projecting a holographic image of an object, the method comprising:

• electronically connecting a mobile communicating and computing device with a holographic projection device;
• and
• projecting a holographic image from the holographic projection device, the holographic image based on a two dimensional image of an object provided by the mobile communicating and computing device;
• wherein the mobile communicating and computing device comprises:
• a power supply source configured to generate and supply power to the mobile communicating and computing device;
• a central processing unit configured to control operations of the mobile communicating and computing device;
• a display screen configured to display the two dimensional image of the object;
• software associated with generating and projecting the holographic image from the two dimensional image of the object provided to said mobile communicating and computing device;
• and
• a light source configured to provide light from the mobile communicating and computing device;
• and
• wherein the holographic projection device comprises:
• a housing;
• a display window disposed on the housing and configured to permit the holographic image to be projected therethrough and into space adjacent said housing;
• an optical element assembly disposed in the housing and comprising a spherical mirror, a circular polarizer, and a beam splitter;
• a slot or pocket or other holding mechanism configured to hold or maintain a connection with the mobile communicating and computing device such that the two dimensional image of the object displayed on the display screen of the mobile communicating and computing device is projected from the display screen and directly received by the optical element assembly for generating the holographic image;
• and
• an electronic connectivity aspect configured to electronically connect the holographic projection device to the mobile communicating and computing device when the mobile computing device is held or maintained in the slot or pocket or other holding mechanism.
