Head up display with displaying plane distance control with freeform variable focusing micromirror array lens system

An AR-HUD (Augmented Reality-Head Up Display) system with displaying multiple planes controlled by freeform variable focusing Micromirror Array Lens System comprising:

• a. a freeform variable focusing Micromirror Array Lens System wherein the freeform variable focusing Micromirror Array Lens System is a MEMS based device comprising a plurality of micromirrors wherein the micromirrors have three degrees of freedom motion and are independently controllable to form freeform optical surface profiles, wherein the freeform optical surface profiles are formed with the independently controlled micromirrors in the freeform variable focusing Micromirror Array Lens System;
• b. a focus controller for controlling the freeform variable focusing Micromirror Array Lens System, wherein the focus controller gives control voltages to each of the micromirror in the freeform variable focusing Micromirror Array Lens System and wherein the focus controller can change the control voltages and changes the freeform optical surface profiles with time;
• c. a display unit wherein the display unit displays two dimensional images with information with time;
• d. an optical module wherein the optical module relays the two dimensional images displayed by the display unit wherein the optical module changes display distance of the module and changes the relaying display surfaces of the display unit by changing the freeform optical surface profiles and wherein the optical module provides images to human eyes with varying distance of the relaying display surfaces;
• and
• e. a display unit controller wherein the display unit controller gives signal to the display unit with time correlated with the focus controller synchronized with the freeform optical surface profiles and the two dimensional images;
• wherein said freeform variable focusing Micromirror Array Lens System varies distances of the relaying display surfaces by the control voltages of the focus controller.
