Special Issue Information

Dear Colleagues,

The rapid growth and implementation of photonic devices in both civil and military systems have reached the stage of applications of the technology in the space.
Photonics has many already perceived benefits for applications in space, such us small size, light weight, high resolution, electromagnetic interference immunity, capability of operating in harsh environment, multiplexing capability, potentially low cost.
Among photonic devices, sensors have been extensively studied in the last decades for different application fields, with different geometrical configurations, materials and detection schemes, resulting in a large number of designs and a wide range of performance.
Specific requirements from the space application field is pushing the development of new photonic sensors to be used on-board, e.g. for structural monitoring of space vehicles, for detection of chemical and biological substances, for high resolution inertial systems, also integrating the sensing systems to the optical communication networks with consequent advantage of using the optical transmission circuits as monitoring ad diagnostic media.
This special issue focuses on photonic sensors for space applications, with the aim of providing research advances on the potential of the sensors to the space field.

Onboard image processing systems for a hyperspectral sensor have been developed in order to maximize image data transmission efficiency for large volume and high speed data downlink capacity. Since more than 100 channels are required for hyperspectral sensors on Earth observation satellites, fast and small-footprint lossless image compression capability is essential for reducing the size and weight of a sensor system. A fast lossless image compression algorithm has been developed, and is implemented in the onboard correction circuitry of sensitivity and linearity of Complementary Metal Oxide Semiconductor (CMOS) sensors in order to maximize the compression ratio. The employed image compression method is based on Fast, Efficient, Lossless Image compression System (FELICS), which is a hierarchical predictive coding method with resolution scaling. To improve FELICS’s performance of image decorrelation and entropy coding, we apply a two-dimensional interpolation prediction and adaptive Golomb-Rice coding. It supports progressive decompression using resolution scaling while still maintaining superior performance measured as speed and complexity. Coding efficiency and compression speed enlarge the effective capacity of signal transmission channels, which lead to reducing onboard hardware by multiplexing sensor signals into a reduced number of compression circuits. The circuitry is embedded into the data formatter of the sensor system without adding size, weight, power consumption, and fabrication cost. Full article

During last two decades, several photon counting detectors have been developed in our laboratory. One of the most promising detector coming from our group silicon K14 Single Photon Avalanche Diode (SPAD) is presented with its valuable features and space applications. Based on the control electronics, it can be operated in both gated and non-gated mode. Although it was designed for photon counting detection, it can be employed for multiphoton detection as well. With respect to control electronics employed, the timing jitter can be as low as 20 ps RMS. Detection efficiency is about 40%in range of 500 nm to 800 nm. The detector including gating and quenching circuitry has outstanding timing stability. Due to its radiation resistivity, the diode withstands 100 krad gamma ray dose without parameters degradation. Single photon detectors based on K14 SPAD were used for planetary altimeter and atmospheric lidar in MARS92/96 and Mars Surveyor ’98 space projects, respectively. Recent space applications of K14 SPAD comprises LIDAR and mainly time transfer between ground stations and artificial satellites. These include Laser Time Transfer, Time Transfer by Laser Link, and European Laser Timing projects. Full article
