Liquid crystal image intensifier tube - has liquid crystal spectral filter and colour display driven in synchronism to enhance night vision |
摘要 |
<p>The appts. comprises an image intensifying tube provided with a liquid crystal spectral fitter at the input end w.r.t. the direction of propagation of light. On the image side is a colour display device. Electric signals applied in synchronism to the fitter and the display, vary in sequence the transmission spectrum and display colour. The appts. allows a spectral analysis of the colour of an object and the restoration of its colour without requiring any movement. It improves the visibility of objects esp. for night vision.</p> |
