    摘要: A compact, ultra-light and high-performance projection optics lens assembly using Diffractive Optics Technology, plastic and glass optics, and Aspheric optics has been designed with only four elements. The lens may be included as is, or scaled to be included in all instruments using conventional Double-Gauss lens forms. The preferred lens is only 20 mm in diameter and 15 mm long has a weight of only 8 g. Thus, two lenses for head mounted stereo displays is only 16 g. Such a stereo display, known as a head-mounted projective display (HMPD), consists of a pair of miniature projection lenses, beam splitters, and miniature displays mounted on the helmet, and retro-reflective sheeting materials placed strategically in the environment.

    摘要: Systems and method for performing simultaneous optical coherence tomography and spectroscopy. In one embodiment, a system includes a light source that emits light to be delivered to a material under evaluation, and a receiver that collects both light that is backscattered by features of the material and fluorescent light that is emitted by features of the material. In one embodiment, a method includes simultaneously collecting near-infrared light backscattered by a material under evaluation and fluorescent light emitted by the material under evaluation using a single light detector.

    摘要: Extremely compact and light-weight optical systems, apparatus, devices and methods to image miniature displays. Such systems include, for example, head-mounted projection displays (HMPD), head-mounted displays (HMDs), and cameras for special effects, compact microscopes and telescopes as well as applications in which magnification and compactness are design criteria. The invention includes an ultra-compact imaging system based on microlenslet arrays and demonstrates that such a system can achieve an object-to-image distance as low as approximately 1.7 mm. with the usage of commercially available microlenslet arrays. The replacement of bulk macro-optical system by multi-aperture micro-optics is achieved.

    摘要: The eye-tracking system is based on the reflection of four light emitting diodes (LED)s at the cornea of user's eve. The LEDs emit infrared light at 900 nanometers and the virtual images formed behind the cornea as well as a near infrared image of the pupil are displayed on a charged couple device (CCD) sensor. The optical system used to display virtual environments is also used to conjugate the virtual images of the LEDs to the CCD sensor. This optimizes the integration of eyetracking system into the head mounted device (HMD). The four LEDs are laid out around the imaging (optical) system and their beam (rays) impinge directly on the eye by reflection on the hot mirror. Then the light reflected by the cornea is reflected again by the hot mirror, goes through the optical system and the cold mirror to be imaged on the sensor. The whole eye is illuminated by near infrared light and the contrast between the dark pupil and the bright iris on the CCD sensor allows knowledge of the location of the center of the entrance pupil. The processing of the location of the cornea images and the center of the entrance pupil leads to determine the sight direction.
