ILLUMINATION AND IMAGING SYSTEM
An illumination and imaging system and method include a light source, an image capture device, a first mirror situated at a predetermined position relative to the light source, and a second mirror situated at a predetermined position relative to the image capture device.
1 . An illumination and imaging system, comprising:
a light source;
an image capture device;
a first mirror situated at a predetermined position relative to the light source; and
a second mirror situated at a predetermined position relative to the image capture device.
2 . The illumination and imaging system of claim 1 , wherein the light source includes a spatial light modulator (SLM).
3 . The illumination and imaging system of claim 1 , wherein the image capture device includes a camera.
4 . The illumination and imaging system of claim 1 , further comprising a computer system interfaced to the light source and the image capture device.
5 . The illumination and imaging system of claim 4 , further comprising a plurality of the first mirrors, wherein the light source is controlled to illuminate a predetermined one of the first mirrors.
6 . The illumination and imaging system of claim 5 , wherein the light source is controlled to simultaneously illuminate a predetermined set of the first mirrors.
7 . The illumination and imaging system of claim 5 , wherein the light source is controlled to illuminate the second mirror.
8 . The illumination and imaging system of claim 4 , further comprising a plurality of the second mirrors, wherein the image capture device is controlled to receive an image from each of the second mirrors.
9 . The illumination and imaging system of claim 8 , wherein the image capture device is controlled to receive an image from the first mirrors.
10 . The illumination and imaging system of claim 5 , wherein the first mirrors are arranged on an oblate spheroid such that a convergence point of chief rays within the light source and a convergence point of rays on an illuminated target are coincident with foci of the oblate spheroid.
11 . The illumination and imaging system of claim 8 , wherein the second mirrors are arranged on an oblate spheroid such that a convergence point of chief rays within the image capture device and a convergence point of rays on an illuminated target are coincident with foci of the oblate spheroid.
12 . The illumination and imaging system of claim 5 , further comprising a plurality of third mirrors, wherein the light source is controlled to illuminate the predetermined one of the first mirrors via a predetermined one of the third mirrors.
13 . The illumination and imaging system of claim 8 , further comprising a plurality of third mirrors, wherein the image capture device is controlled to receive the image from the second mirrors via the third mirrors.
14 . The illumination and imaging system of claim 1 , wherein the light source is configured to illuminate the target using structured light.
15 . A manufacturing method including an illumination and imaging method, comprising:
illuminating a target via a first mirror situated at a predetermined position; and
capturing an image of the illuminated target via a second mirror situated at a predetermined position.
16 . The method of claim 15 , further comprising simultaneously illuminating the target via a plurality of the first mirrors.
17 . The method of claim 15 , further comprising capturing the image of the illuminated target via a plurality of the first mirrors.
18 . The method of claim 15 , further comprising illuminating the target via the first mirror via a third mirror.
19 . The method of claim 15 , further comprising capturing the image of the illuminated target via the second mirror via a third mirror.
20 . The method of claim 15 , wherein illuminating the target includes illuminating the target using structured light.
21 . The method of claim 15 , wherein the target is a surface of a part, and wherein the method further comprises assembling the part into a final assembly.
22 . The method of claim 21 , wherein the part is an electronic component, and wherein the method further comprises mounting the electronic component on a circuit board.
