A simple method has been proposed here to get an enhanced and constant-value transient diffraction efficiency for a large time scale from a recorded grating in an undoped BaTiO3 crystal. After writing a steady-state grating by two cw recording beams

The imager presented in this paper has a special blocking structure that ensures very low dark current of less than 1 pA/mm2 even with a 20 V/μm electric field. Hence the electric field can be increased from the generally applied 10 V/μm to 20V/μm

We enhanced the photoelectric conversion efficiency of red light in a 15-mm-thick HARP film without deteriorating image pick-up characteristics or reliability. To achieve a higher photoelectric conversion efficiency for red light, we designed a new f

We developed an ultrahigh-sensitivity camera tube with a 15-µ m-thick high-gain avalanche rushing amorphous photoconductor (HARP) film and applied it to an HDTV camera. The camera, called the "New Super-HARP", can achieve about 30 times the sensitiv

Microactuator systems usually consist of distributed microactuators. For package control circuits in such a micro system, a decentralized control scheme is required. This paper proposes the decentralized control scheme for distributed microactuators

The New Super-HARP image sensor, which relies on avalanche multiplication in a photoconductive film made mainly of amorphous selenium, is ultra-high sensitive. The sensor has already ben used to film very dark scenes, however in such a situation, sho

In this paper, we propose, for the first time to our knowledge, utilizing GAWBS for sensing temperature or tensile strain and experimentally demonstrate the GAWBS fiberoptic temperature sensor.

In the above paper on a transient analysis based on the multiplebeam interference method [1], some errors have been discovered. In this note, we detail corrections and discuss the validity of the multiple-beam interference method by comparison with a
