What type of IR detector configuration produces the entire image all at once?

The imaging infrared (IR) detector configuration is designed to produce an entire image all at once, distinguishing it from other configurations that may capture data in a different manner. Imaging IR detectors consist of a two-dimensional array of pixel sensors, similar to how a digital camera operates. This allows for capturing a full thermal image in a single frame, providing comprehensive visual information in a rapid response time.

This characteristic is particularly useful for applications such as surveillance, search and rescue, and diagnostics, where timely and complete visual data is critical. The performance of imaging IR detectors, due to their active pixel architecture, leads to enhanced resolution and clarity in the images captured, making them advantageous in various fields where detailed thermal imaging is essential.

Other configurations, such as elemental or thermal detectors, may operate by sequentially scanning the scene or by only registering temperature changes without providing a full image, which is why they do not match the capability of the imaging configuration.
