Calorimetric energy detector for space debris

Characterizing hypervelocity (>2.5 km/s)-impact-engendered damage in shielding structures using in-situ acoustic emission: Simulation and experiment

“…This is of vital importance and necessity for those spacecraft with long service time or with large surfaces exposed to the space environment. Addressing such significant and imminent needs, several sensing and diagnostic techniques have been deployed, as typified by those using acoustic emissions (AEs) [14,15], acceleration-based detection [16], thermography [17], calorimetry [18], fiber optic sensor-based detection [19], resistor-based detection [20], microwave emissions, [21] and camera-based surface inspection [22]. All these techniques have been systematically graded by the Inter-Agency Space Debris Coordination Committee [13], in terms of the levels of their respective sensitivity, accuracy, and manipulability, and AE ranked top among all the above mentioned techniques.…”
