AEG has successfully developed a family of PtSi detection modules to cover various applications. The development was performed in a cooperation with Daimler Benz Research and Technology F2M and Telefunken Microelectronic TEMIC EZIS. The modules are designed around 2 staring PtSi focal plane arrays (FPA) having 256 X 256 pixels or 640 X 486 pixels, respectively. Both arrays are identical in their basic features like 24 micrometers pitch, > 60% fillfactor, variable integration time, optional interlaced and non interlaced rolling frame readout, subframe capability and excellent thermal resolution with measured values for the NETD < 70 mK (300 K, 20 ms, F/1.4). The FPA's are integrated either in integrated dewar cooler assemblies with a 1/3 W split linear compressor for the 256 X 256 FPA or a 1 W split linear compressor for the 640 X 486 FPA, respectively, or designed for the use in seeker applications with a Joule Thomson cryocooler (640 X 486 FPA only). The modules are completed by different miniaturized types of electronics, providing all DC and clock supplies to drive the FPA's and providing the customer with either a buffered analog or a 14 Bit resolution digital interface. Digital signal processor (DSP) based image correction units were developed for testing the units. The DSP boards provide the ability for freely programmable real-time functions like 2 point correction or other data manipulations in camera applications. The modules and their key features are reviewed together with their performance data.
