  • Patent number: 11513223
    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.
    Type: Grant

  • Patent number: 10921450
    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.

  • Patent number: 10656272
    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.

  • Patent number: 10641897
    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.

  • Publication number: 20060235660
    Abstract: A facility provides functionality for performing customized analysis on finite element models. The facility may include a finite element post processing framework, wherein the finite element post processing framework is not specific to a particular finite element model. The facility may also include an interface component configured to receive input from an end user, wherein the interface component receives input associated with customizing the post processing framework so that it can be applied to a specific finite element model. The facility may then perform processing, such as post processing, on the specific finite element model based on customizing the post processing framework.
