Abstract: A sensor for detecting environmental media and pressure comprises two types of optical fibers. An intrinsic fiber containing a portion of the fiber with the jacket removed is sensitive to its surroundings as some light traveling through the fiber will escape. The change in light intensity is received by a light detector, and this information is interpreted to correspond to a certain media, a change in media, or a phase change in media. An extrinsic fiber with a membrane and mirror located at one end is placed vertically in the media. Pressure from the media changes the position of the membrane and the mirror, resulting in a change in the intensity of the light reflected back through the fiber to the light detector. The pressure can then be used to determine the volume of the media in the container. Pressure determination can be continuous. In addition, both types of sensors can be networked, allowing information from one sensor to influence the gathering of information from the other.

Abstract: According to the present invention, a photomultiplier tube is used with a high-speed feedback mechanism to continuously modulate the gain of the tube in response to the size of the input signal. The gain of the tube and the anode current are independently converted to ideal logarithms. These signals are then subtracted from one another to reconstruct a true logarithmic representation of the optical signal. This log-light-level signal has a higher dynamic range and faster temporal response than has previously been achieved by other methods.
