HC Deb 31 January 1968 vol 757 cc358-9W
Mr. Dalyell

asked the Minister of Technology what research he does on photo-detectors.

Mr. Benn

The work programmes at two of my Department's research and development establishments include research on photo-detection. Contracts have also been placed with some of the universities and with industry for research and development in this field. Work at the establishments and universities is mainly concerned with the basic phenomena on which is founded the further development being caned out under contract in industry. The main military applications are in the fields of night vision and improved photo-reconnaissance, but some aspects have important civil potential.
