Advancing High-Speed Object Analysis with CDS’s PDP Technology in Infrared Sensor Applications
CDS’s Packetized Display Protocol (PDP) technology is a critical component in infrared sensor testing, especially when working with high-speed objects such as supersonic projectiles or space debris. PDP’s capacity to handle multiple frame rates concurrently enables efficient simulation and analysis of rapidly moving targets.
PDP employs a physical layer independent method of pixel data transmission, providing latency guarantees while maximizing performance. By transmitting small sub-windows of data at increased apparent frame rates, PDP achieves faster decoding and display throughout the array, while preserving full-resolution modes of operation. This functionality is essential for applications like tracking or detecting high-speed objects in advanced infrared sensor testing.
CDS’s PDP technology has been demonstrated in various scenarios, highlighting its ability to manage intricate multi-frame scenes involving high-speed targets. For example, during a demonstration at the Air Force Research Lab (AFRL) on NSLEDS 5, a 100Hz PDP background was combined with an 800Hz hot object, simulating the swift motion of a high-speed target.

The scene was captured using FLIR’s latest X69 series IR cameras which then had to be windowed down extensively to match CDS’ 20kHz IRLED Scene Projector System.
Furthermore, CDS’s PDP technology has been utilized in a 20kHz demonstration, featuring a hot object traversing a 1024×1024 spatial resolution IRLED array. This scene was captured using FLIR’s cutting-edge X69 series IR cameras, which required extensive windowing to match CDS’ 20KHz IRLED Scene Projector System.
In conclusion, CDS’s PDP technology significantly enhances the infrared sensor testing process by enabling the simulation and analysis of high-speed objects such as supersonic projectiles and space debris. Its ability to manage multiple frame rates and maintain high-resolution modes of operation greatly contributes to the precision and efficacy of infrared sensor applications.

Apparent Temperatures
Engineered to perfection, the CDS IRLED Scene Projector is specifically designed to represent high apparent temperature objects within full-frame backgrounds with peerless accuracy, delivering unmatched fidelity to infrared sensors. The cornerstone of this projector lies in its exceptional 16-bit resolution and multi-gear system, enabling an extensive array of colors and brightness levels, thereby elevating the overall image quality discernible by advanced IR sensors.
To guarantee unparalleled precision and superior contrast in imagery, the CDS IRLED Scene Projector is equipped with a 30mK temperature resolution. This extraordinary capability allows the projector to faithfully render hot objects and their surrounding environments, discerning even the most minute temperature variations with exceptional detail. As a result, the CDS IRLED Scene Projector delivers accurate and hyper-realistic IR scenes, satisfying the requirements of a myriad of applications demanding precise temperature representation and visualization.
The projector achieves a maximum apparent temperature of 1,450 K within the 3-5μm band. However, with a 99.98% NUC (Non-Uniformity Correction) applied, this maximum apparent temperature is reduced to 1,220 K. The range of apparent temperatures that the CDS IRLED Scene Projector can accurately reproduce is as follows:
● Maximum Apparent Temperature (with 99.98% NUC applied): 1,220 K
● Maximum Apparent Temperature (in 3-5μm): 1,450 K
These robust features solidify the CDS IRLED Scene Projector’s standing as a leader in accurate and realistic IR scene representation. It showcases a wide array of temperatures with remarkable accuracy and exquisite detail. This meticulously crafted, technologically advanced tool reshapes the boundaries of infrared visualization, emerging as an indispensable resource for professionals engaged in advanced IR sensor technologies.
