FLASH LIDAR SENSOR ASSEMBLY
A flash lidar sensor assembly includes a first housing and at least one laser light source disposed in the first housing. The at least one laser light source is configured to generate a first field of illumination of light and a second field of illumination of light. The assembly also includes a second housing separate from the first housing. A first light receiver unit and a second light receiver unit are disposed in the second housing. The first light receiver unit is configured to receive light of the first field of illumination reflected off at least one object. The second light receiver unit is configured to receive light of the second field of illumination reflected off at least one object.
1 . A flash lidar sensor assembly comprising:
a first housing;
at least one laser light source disposed in said first housing for generating a first field of illumination of light and a second field of illumination of light;
a second housing separate from said first housing; and
a first light receiver unit and a second light receiver unit disposed in said second housing;
said first light receiver unit configured to receive light of the first field of illumination reflected off at least one object; and
said second light receiver unit configured to receive light of the second field of illumination reflected off at least one object.
2 . The flash lidar sensor assembly as set forth in claim 1 , further comprising:
a first optical element configured to receive light from said at least one laser light source and generate the first field of illumination; and
a second optical element configured to receive light from said at least one laser light source and generate the second field of illumination.
3 . The flash lidar sensor assembly as set forth in claim 2 , wherein said at least one laser light source is a single laser light source.
4 . The flash lidar sensor assembly as set forth in claim 3 , further comprising a mirror configured to varyingly direct light from said laser light source to said first optical element and said second optical element.
5 . The flash lidar sensor assembly as set forth in claim 4 , wherein each of said optical element includes a lens.
6 . The flash lidar sensor assembly as set forth in claim 5 , further comprising at least one beam splitter for directing some of the light generated by said single laser light source to said mirror and directing some of the light generated by said single laser to a fiber optic.
7 . The flash lidar sensor assembly as set forth in claim 6 , further comprising an optical splitter in optical communication with said fiber optic, said first light detector, and said second light detector, and configured to guide light from said fiber optic to said detectors.
8 . The flash lidar sensor assembly as set forth in claim 6 , wherein said second housing defines an exit aperture and said fiber optic is in optical communication with said exit aperture to define a third field of illumination.
9 . The flash lidar sensor assembly as set forth in claim 6 , further comprising a controller in communication with said single laser light source, said mirror, said first light detector, and said second light detector.
10 . The flash lidar sensor assembly as set forth in claim 7 , wherein said controller is disposed remote from said first housing.
11 . The flash lidar sensor assembly as set forth in claim 10 , wherein said controller is disposed separate from said second housing.
