✦ Synopsis

Quality of information retrieved from digitally compressed in-line holograms are objectively studied by evaluating the measured recording distance and its reconstructed image. A lossy-JPEG algorithm is used for compression of the in-line Fraunhofer holograms, while the information retrieval is accomplished by using complex amplitude based numerical reconstruction method. The results show that the error in measurement of recording distance and the degradation of the reconstructed image are not significant although the hologram is compressed by about 60 times. This provides a practical solution to the storage and data transfer problems in on-line digital in-line holography.

Several automated crystallization systems have recently been developed for high-throughput X-ray structure analysis. However, the evaluation process for the growth state of crystallizing protein droplets has not yet been completely automated. This paper proposes a new evaluation method for crystalli
