US10921450B2
Ladar system and method with frequency domain shuttering
Publication/Patent Number: US10921450B2 Publication Date: 2021-02-16 Application Number: 16/407,570 Filing Date: 2019-05-09 Inventor: Dussan, Luis Carlos   Steinhardt, Allan   Greene, Jordan Spencer   Wang, Allen Chi-luen   Vyas, Nitin   Rejaly, Daryoosh   Assignee: AEYE, INC.   IPC: G01S17/00 Abstract: A ladar system and related method are disclosed where a ladar transmitter transmits ladar pulses toward a plurality of range points, and a ladar receiver receives ladar returns from the range points, wherein the ladar receiver comprises a photo receiver. A sensor can be used to sense background light levels, and a control circuit can (1) measures the sensed background light levels and (2) provide frequency domain shuttering with respect to the photo receiver based on the measured background light levels.

Ladar System and Method with Frequency Domain Shuttering
Publication/Patent Number: US2020341146A1 Publication Date: 2020-10-29 Application Number: 16/407,570 Filing Date: 2019-05-09 Inventor: Dussan, Luis Carlos   Steinhardt, Allan   Greene, Jordan Spencer   Wang, Allen Chi-luen   Vyas, Nitin   Rejaly, Daryoosh   Assignee: AEYE, Inc.   IPC: G01S17/10 Abstract: A ladar system and related method are disclosed where a ladar transmitter transmits ladar pulses toward a plurality of range points, and a ladar receiver receives ladar returns from the range points, wherein the ladar receiver comprises a photo receiver.

US10641897B1
Ladar system and method with adaptive pulse duration
Publication/Patent Number: US10641897B1 Publication Date: 2020-05-05 Application Number: 16/407,544 Filing Date: 2019-05-09 Inventor: Dussan, Luis Carlos   Steinhardt, Allan   Greene, Jordan Spencer   Wang, Allen Chi-luen   Vyas, Nitin   Rejaly, Daryoosh   Assignee: AEYE, INC.   IPC: G01S17/26 Abstract: A ladar system and related method are disclosed where the ladar system includes a sensor that senses background light levels. A control circuit of the ladar system (1) measures the sensed background light levels and (2) controllably adjusts a pulse duration for a new ladar pulse based on the measured background light levels. A ladar transmitter can then transmit the new ladar pulse, wherein the new ladar pulse has the adjusted pulse duration. In an example embodiment, this technique for adaptive pulse duration can be employed in the ladar system where the ladar transmitter and ladar receiver are arranged in a bistatic architecture.

US10656272B1
Ladar system and method with polarized receivers
Publication/Patent Number: US10656272B1 Publication Date: 2020-05-19 Application Number: 16/407,589 Filing Date: 2019-05-09 Inventor: Dussan, Luis Carlos   Steinhardt, Allan   Greene, Jordan Spencer   Wang, Allen Chi-luen   Vyas, Nitin   Rejaly, Daryoosh   Assignee: AEYE, INC.   IPC: G01S17/10 Abstract: A ladar system and related method are disclosed where the ladar system comprises first and second receivers. The first receiver receives a ladar return from a ladar pulse with a known transmit polarization. The second receiver receives the ladar return from the ladar pulse with the known transmit polarization. The ladar system also includes a control circuit that (1) measures incident polarizations at the first and second receivers with respect to the received ladar return and (2) separates a retro-reflective portion of the received ladar return from a non-retro-reflective portion of the received ladar return based on the measured incident polarization and the known transmit polarization.

US2020341147A1
Ladar System and Method with Cross-Receiver
Publication/Patent Number: US2020341147A1 Publication Date: 2020-10-29 Application Number: 16/407,626 Filing Date: 2019-05-09 Inventor: Dussan, Luis Carlos   Steinhardt, Allan   Greene, Jordan Spencer   Wang, Allen Chi-luen   Vyas, Nitin   Rejaly, Daryoosh   Assignee: AEYE, Inc.   IPC: G01S17/10 Abstract: A ladar system and related method are disclosed where the system includes a ladar transmitter and a ladar receiver. The ladar transmitter transmits ladar pulses into a field of view, and the ladar receiver receives ladar pulse returns from objects in the field of view. The ladar receiver comprises a cross-receiver, the cross-receiver comprising a first 1D array of photodetector cells and a second 1D array of photodetector cells that are oriented differently relative to each other.
