Abstract
SCD has developed a High Performance Detector Dewar Cooler (DDC) called “Piccolo” for IR detection in the MWIR, which has low power consumption, low weight and low cost. The DDC characteristics are optimized for handheld camera applications. The Piccolo DDC is based on the advanced “Blue Fairy” Focal Plane Processor (FPP) which is bonded to a 320x256 element InSb FPA. The Blue Fairy FPP is used in a special mode of operation for very low power consumption of less than 25mW. A special dewar has been developed for the Piccolo which has a low heat load of less than 140mW. A new cooler designed for low power consumption and low weight is integrated into the dewar. This results in a total power consumption for the DDC at an ambient temperature of 23°C of below 5W. The total weight of the whole DDC is less than 400gr. All the components of the Piccolo were designed for low cost production while keeping the high performance and reliability standards of all SCD detectors.
