TL;DR: In this paper, a 50mm-diameter BSO single crystal with good properties was grown with the newly developed crystal pull-ing system, which was fabricated into an ITC device with 35×35mm2 active area and 200, um to 400μm thickness.
Abstract: Bi12SiO20 Incoherent-To-Coherent image conversion devices (abbreviated as BSO-ITC devices) are the most suitable devices for optical image processing systems, because of their high sensitivity and rather small half-wave voltage. In order to develop high storage capacity BSO-ITC devices, a 50mm-diameter BSO single crystal with good properties was grown with the newly developed crystal pull-ing system. This crystal was fabricated into an ITC device with 35×35mm2 active area and 200, um to 400μm thickness. The write-in sensitivity to produce 1/100 output intensity decay was 2, 000 erg/cm2. Modulation Transfer Function which was measured by optical Fourier transform of a coherent read-out image was 0.5 at the spatial frequency of 15-20 1p/mm. The total storage capacity was 525 1p × 525 1p and comparable to that of a high resolution vidicon.
