Systems and methods for display binocular deformation compensation

A display subsystem for a virtual image generation system used by an end user, comprising:

• a frame structure having a frame;
• first and second waveguide apparatuses carried by the frame;
• first and second projection subassemblies configured for introducing first and second light beams respectively into the first and second waveguide apparatuses, such that at least a first light ray and at least a second light ray respectively exit the first and second waveguide apparatuses to display first and second monocular images as a binocular image to the end user;
• and
• a light sensing assembly configured for detecting at least one parameter indicative of a mismatch between the displayed first and second monocular images as the binocular image, wherein the light sensing assembly is stably mounted on a portion of the frame structure that is flexibly coupled to the frame, such that deformation of the frame may cause the first and second waveguide apparatuses to misalign relative to each other without moving the light sensing assembly, thereby rigidly decoupling the light sensing assembly from the first and second waveguide apparatuses.
