Lobster Eye Imager for Astronomy

[3][4][5] LEIA has a sensor module giving it a field of view of 340 square degrees.

[2][3] In 2022 August and September, LEIA carried out a series of test observations for several days as part of its performance verification phase.

A number of preselected sky regions and targets were observed, including the Galactic Center, the Magellanic Clouds, Sco X-1, Cas A, Cygnus Loop, and a few extragalactic sources.

[1] Developed by the CAS's Innovation Academy for Microsatellites, SATech-01 is an exploration satellite aimed at test and demonstration of the new technologies of some 16 scientific experiments, ranging from astrophysics to solar physics, Earth observation to space environment monitoring.

The satellite, with a designed lifetime of 2 yr, is in a Sun-synchronous near-Earth circular orbit with a period of 95 minutes.

Configuration of the focusing mirror system, focal detector array, and FoV of LEIA. The mirror assembly is divided into four individual quadrants, each consisting of 3 × 3 MPO plates and associated with one of the four detectors. The overall FoV of the telescope module is 18fdg6 × 18fdg6. [ 1 ]
