| Abstract: |
Aerius Photonics proposes the development of a unique FPA sensor that accommodates the requirements of this application. In Phase II, Aerius will develop a 640 X 640 30m InGaAs detector array based FPA sensor that has both the ability to detect low power laser pulses through integration and perform low-light level imaging in a single FPA. The detector array can support both 1064 nm and 1550 nm laser pulses. Aerius and their partner have collaborated on ROIC unit cell circuitry to support the Dual Well FPA concept. The unit cell design supports two charge integration paths. One path integrates the background scene to provide a high fidelity image of the scene. The second path integrates the laser pulse return to pull the signal out of the background noise. Detection of the input return pulse will be determined in conjunction with the back end digital signal processor. In Phase I, Aerius will build a 16x16 InGaAs array to demonstrate the dual well detection concept. |
| Benefits: |
The dual well sensor will have applications wherever a pulsed laser beam is needed to be superimposed on a high fidelity image. This has both defense and commercial applications. The benefit for the military is the ability to superimpose both rangefinder and designator spots on an image. This type of instrument can be used by the soldier as well as airborne and naval applications. For commercial applications, the dual well sensor is useful for industrial spot tracking for automation systems. |
