Abstract
Techniques are disclosed for display systems and methods associated with pulse detection and imaging. In one example, a system includes an imaging device configured to capture an image that includes a light pulse of a pulse sequence. The system further includes a display device. The display device is configured to receive data associated with the pulse sequence, where the data includes a location of the light pulse. The display device is further configured to display the image and an overlay on the image. The overlay is indicative of the location of the light pulse. Related devices and methods are also provided.

A system comprising:
- a light pulse detection device configured to:
- detect a first mid-wave infrared (MWIR) light pulse;
- detect a second MWIR light pulse;
- determine that the first MWIR light pulse is associated with a first pulse sequence based at least on a time difference between detection of the first MWIR light pulse and detection of the second MWIR light pulse;
- determine first timing information associated with a third MWIR light pulse of the first pulse sequence, wherein the third MWIR light pulse is subsequent to the first MWIR light pulse;
- and
- generate first data associated with the first timing information;
- an imaging device configured to:
- determine a first integration period based on the first data;
- and
- capture, using the first integration period, a first image that includes the third MWIR light pulse of the first pulse sequence;
- and
- a display device configured to:
- receive data associated with the first pulse sequence, wherein the data comprises a location of the third MWIR light pulse;
- and
- display the first image and a first overlay on the first image, wherein the first overlay is indicative of the location of the third MWIR light pulse.
