ABSTRACT:
An improved detector having a reflective surface which is substantially insensitive to vibration. The detection surface comprises a thin layer of liquid metal which is disposed over a substantially rigid, wettable substrate. In a presently preferred embodiment, the detector comprises a receptacle having disposed therein a rigid brass plate covered by a thin layer of mercury. The detector is submersed in a suitable fluid, such as water, to which an acidic substance has been added to reduce the pH of the fluid to the range of 5 to 6.
