(p. 487) FOREWORD When about five years ago I learned first of Professor McGee’s intention to organize a symposium on Photo-Electronic Image Devices, I was curious to know how publication of the proceedings of such a symposium, as a special volume for Advances, would be received by its readers. The reception was so good that I had not the slightest hesitation to propose to Professor McGee again publication of the Proceedings, as soon as I learned from him that he was to organize a second symposium. Negotiations were very smooth, and the results are presented here to the scientific public. I hope that it will be received as well as or even better than its predecessor. It has been by custom lately to list the items which we hope to treat in the coming volumes of Advanceu. Listing without authors, however, led to confusion : a number of people interpreted my listing as a request for authors, whereas I listed subjects only after preliminary agreements with prospective authors. I will, therefore, give below both the subject and author for the expected contributions in the next few volumes of Advances in Electronics and Electron Physics : P. A. REDHEADJ., P.

July 1962 PREFACE In September 1958 a Symposium on I'hoto-Electronic Image Devices as Aids t'o Scientific Observation. which we believe was the first devoted exclusively to this form of instrumentation, was held in London at the Imperial College of Science and Technology, and tlhe Proceedings were subsequently published as Volume XI1 of Advances in Electronics and Electron, Physics. The success of that meeting, and our awareness of increasing interest in the subject. encouraged us to hold a second symposium witlh the same title at, t,he Imperial College in September 1961, and the papers presented are collected in the present book. It is nearly twice the length of the Proceedings of the 1958 meeting, and includes a greater variety of devices and applications, which reflect the growth of activity in the field and confirm our judgement that the interval of three years between the meetings was not too short to show significant developments. We are sorry that we did not succeed in attempts to arrange for Soviet scientists, who have niade such notable contributions in the field, to take part in the Symposium; but otherwise we believe it was broadly representative of research workers throughout the world, and we are grateful to all those who came to London to make it so. We are also particularly grateful to the authors of papers for the co-opera- tion they have given us. It is a pleasure to record our thanks to our secretary, Miss N. C. Little, for her help. both in the organization of the Symposiuni itself, and subsequently while we have been preparing these Proceedings for publication. J. I). MCGEE W. I,. WILCOCK rA. MANDEL
