Jun 13, 2000

Appl. No.:

09/592899

Inventors:

Wei Su - Sunnyville CA
Norbert A. Massie - San Ramon CA

Assignee:

Massie Research Laboratories, Inc. - Dublin CA

International Classification:

A61B 314

US Classification:

351206

Abstract:

A digital camera that combines the functions of the retinal camera and corneal camera into one, single, small, easy to use instrument. The single camera can acquire digital images of a retinal region of an eye, and digital images of a corneal region of the eye. The camera includes a first combination of optical elements for making said retinal digital images, and a second combination of optical elements for making said corneal digital images. A portion of these elements are shared elements including a first objective element of an objective lens combination, a digital image sensor and at least one eyepiece for viewing either the retina or the cornea. The retinal combination also includes a first changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said retinal region at or approximately at a common image plane. The retinal combination also includes a retinal illuminating light source, an aperture within said frame and positioned within said first combination to form an effective retinal aperture located at or approximately at the lens of the eye defining an effective retinal aperture position, an infrared camera for determining eye position, and an aperture adjustment mechanism for adjusting the effective retinal aperture based on position signals from said infrared camera. The cornea combination of elements includes a second changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said cornea region at or approximately at a common image plane.

Appl. No.:

12/138575

Inventors:

Norbert A. Massie - San Ramon CA, US

Assignee:

Phoenix Research Laboratories - San Ramon CA

International Classification:

A61B 3/10
A61B 3/00

US Classification:

351214, 351246, 351219

Abstract:

Imaging an eye of an animal can include injecting a ring of light through an outer portion of an entrance pupil of the eye of the animal onto a back interior portion of the eye. Light reflected off of the back interior portion of the eye and through an exit pupil effectively located at the entrance pupil within the ring of light can be collected. A diameter of the exit pupil at the entrance pupil can be less than an inner diameter of the ring of light, and a difference between an outer diameter of the ring and the inner diameter of the ring can be at least twenty percent of a diameter of the eye. The collected light reflected off of the back interior portion of the eye can be focused to thereby form an image of the back interior portion of the eye.

International Classification:

G01B 1102

US Classification:

356358

Abstract:

In multi-telescope arrays that comprise multiple telescopes, a beam-combining module, and flat mirrors for directing light beams from the multiple telescopes to the beam combining module, a laser metrology system is used for monitoring various pathlengths along a beam path where deviations are likely. Some pathlengths are defined simply by a pair of retroreflectors or reflectors at both ends. Lengths between pairs of retroreflectors are measured and monitored by laser interferometers. One critical pathlength deviation is related to the displacement of the flat mirror. A reference frame is set up relative to the beam-combining module to form and define the coordinate system within which the positions of the flat mirrors are measured and monitored. In the preferred embodiment, a pair of retroreflectors along the optical axis of the beam-combining module defines a reference frame. A triangle is formed by the reference frame as the base and another retroreflector at the flat mirror as the vertex.
