AST-9731165 ABSTRACT A new approach to speckle imaging using a large format CCD will be developed. In this technique many speckle patterns will be accumulated along a subarray strip of the chip. When the strip is full, all the patterns are read out together. This method can reduce the read time overhead and allow for efficient speckle imaging. In this way, large format slow-readout CCDs, which are already widely used in astronomy, can be used for high-resolution imaging with little change in hardware.

AST-9731165 摘要 提出了一种利用大面阵CCD进行散斑成像的新方法。 在该技术中，许多散斑图案将沿芯片的子阵列条沿着累积。 当条带满时，所有图案一起被读出。 该方法可以减少读取时间开销并允许有效的散斑成像。 通过这种方式，已经广泛应用于天文学的大格式慢读出CCD可以用于高分辨率成像，而硬件变化很小。
