A head mounted display (HMD) system employs a holographic element in the optical path of the HMD to direct light to a user's eye. The HMD includes a micro-display, a lightguide, and a holographic element coupled to the lightguide.

The present invention discloses a method for detecting a microstructure of a functionally graded material based on digital acousto-optic holography, including the following steps: excite a sample with an ultrasonic wave; record a light wave; form a single tomographic acousto-optic hologram; perform numerical reconstruction of phase information, and perform global detection. The present invention uses an acoustic-optic modulation device to modulate a laser light source of a laser of a laser device to form two light waves of different frequencies. The two light waves each constitute a Mach-Zehnder interference system to record reflection wave information and transmission wave information of an ultrasound, and are finally combined and recorded in the same hologram to form the single tomographic acousto-optic hologram. A reflection-transmission dual-mode interference optical path is beneficial to avoiding the mutual interference of the reflection wave information and the transmission wave information, and being able to improve the integrity of information record and information redundancy by using time delay integration with point sensing and surface output to scan CCD through an image collector and cooperate with a synchronous control system to perform surface scanning and record for information of an ultrasound carrier.
