Imaging systems, including imaging systems for AR/VR devices, and associated systems, devices, and methods
Imaging systems, including imaging systems for AR/VR devices, and associated systems, devices, and methods are described herein. In one embodiment, an imaging system includes a lens arrangement operably connected to a camera. The lens arrangement can include a macro lens removably connected to an eyepiece with the macro lens positioned between the eyepiece and the camera. The eyepiece can be positioned at a distalmost end portion of the lens arrangement and/or such that an afocal side of the eyepiece is directed away from the macro lens. The lens arrangement can include a baffle removably connected to the macro lens and/or removably connected to the eyepiece. The macro lens can be electronically and/or automatically focused. A length of the lens arrangement and/or a position of the eyepiece can remain unchanged while the macro lens is focused. In some embodiments, the lens arrangement has a folded configuration and/or includes a minor.
1 . An imaging system for measuring a device under test (DUT), the imaging system comprising:
a camera; and
a lens arrangement operably connected to the camera, wherein the lens arrangement includes a macro lens removably connected to an eyepiece, wherein the eyepiece is an ocular lens that is repositionable with respect to the DUT, and wherein the macro lens is positioned between the camera and the eyepiece,
wherein the lens arrangement is transitionable to a folded configuration, and
wherein the lens arrangement further comprises a baffle operably connecting the eyepiece to the macro lens, and wherein—
the baffle is removably connected to the macro lens and/or to an eyepiece mount housing the eyepiece; and
the baffle is configured to shield an interior of the lens arrangement from stray light not introduced into the interior of the lens arrangement via the eyepiece.
2 . The imaging system of claim 1 wherein the eyepiece is positioned in the lens arrangement such that an afocal side of the eyepiece is directed away from the macro lens.
3 . The imaging system of claim 1 wherein the eyepiece is positioned at or near a distalmost end of the lens arrangement and/or of the imaging system such that an entrance pupil of the imaging system is not buried in the lens arrangement.
4 . The imaging system of claim 1 wherein the eyepiece is positioned such that an exit pupil of the eyepiece is an entrance pupil of the imaging system.
5 . The imaging system of claim 1 wherein the lens arrangement further comprises a mirror.
6 . The imaging system of claim 1 wherein the macro lens is electronically and/or automatically focusable.
7 . The imaging system of claim 1 wherein a length of the lens arrangement remains unchanged while (i) the macro lens is removably connected to the eyepiece and (ii) the macro lens is focused.
8 . The imaging system of claim 1 wherein a position of the eyepiece remains unchanged while (i) the macro lens is removably connected to the eyepiece and (ii) the macro lens is focused.
9 . The imaging system of claim 1 , further comprising an aperture positioned in front of the eyepiece on a side of the eyepiece opposite the macro lens.
10 . The imaging system of claim 9 wherein a dimension of the aperture is mechanically or electronically adjustable.
11 . The imaging system of claim 1 , further comprising a teleconverter positioned between the camera and the macro lens.
12 . The imaging system of claim 1 wherein the imaging system is configured to capture spatial images of the DUT.
13 . The imaging system of claim 1 wherein the imaging system is configured to capture non-spatial images of the DUT.
14 . The imaging system of claim 13 wherein the imaging system is configured as a conoscope such that the imaging system measures angular properties of light emitted, reflected, or scattered by or from the DUT.
15 . A system, comprising:
a first imaging system including a first camera and a first lens arrangement, wherein the first lens arrangement includes a macro lens removably connected to an eyepiece, and wherein the macro lens is positioned between the first camera and the eyepiece; and
a second imaging system including a second camera and a second lens arrangement,
wherein at least one of the first lens arrangement or the second lens arrangement has a folded configuration,
wherein the first lens arrangement further comprises a baffle operably connecting the eyepiece to the macro lens, and wherein—
the baffle is removably connected to the macro lens and/or to an eyepiece mount housing the eyepiece; and
the baffle is configured to shield an interior of the first lens arrangement from stray light not introduced into the interior of the first lens arrangement via the eyepiece.
16 . The system of claim 15 wherein:
the eyepiece is positioned in the first lens arrangement such that an afocal side of the eyepiece is directed away from the macro lens; and/or
the macro lens is electronically and/or automatically focusable.
17 . The system of claim 15 wherein the first imaging system and the second imaging system are arranged side-by-side, and wherein the first imaging system and the second imaging system are positioned in a same orientation.
18 . The system of claim 15 wherein:
the first imaging system and the second imaging system are arranged side-by-side; and
the first imaging system is positioned in a first orientation and the second imaging system is positioned in a second, different orientation.
19 . The system of claim 15 wherein the first imaging system and the second imaging system are configured to take simultaneous measurements of one or more devices under test (DUTs).
20 . The system of claim 15 wherein the first imaging system, the second imaging system, or both the first and second imaging systems are configured to capture spatial images of a device under test (DUT).
21 . The system of claim 15 wherein the first imaging system, the second imaging system, or both the first and second imaging systems are configured to capture non-spatial images of a DUT.
22 . The system of claim 21 wherein the first imaging system, the second imaging system, or both the first and second imaging systems are configured as a conoscope to measure angular properties of light emitted, reflected, or scattered by or from the DUT.
