By proper chamber charging, the unit can be adjusted to provide a suitable signal from the CdS cell after the predetermined dose is exceeded. The sensor is a pencil ionization chamber modified to include an illuminated quartz fiber, an optical system, and a CdS light more » detector. The dosimeter which alarms has a dose range of 0 -200 mr however, with different sensors, this range can be extended up to 0-600 r. Both are adaptable to radiotelemetry methods of information transfer. The second provides digital indication of the received dose on a miniature register. One audibly alarms after a predetermined dose is accumulated. Two experimental pocket-size radiation dosimeters were developed to provide either an indicated measurement of accumulated dose or suitable alarming for preselected dose levels. Finally, RMI and microphone tests on the rover demonstrate the capabilities of these subsystems as well. Luminescence spectra demonstrate the utility of having both spectral and temporal dimensions. Examples of Raman and VISIR spectroscopy are shown, demonstrating clear mineral identification with both techniques. Thermal systems maintain a warm temperature during cruise to Mars to avoid contamination on the optics, and cool the detectors during operations on Mars.Results obtained with the integrated instrument demonstrate its capabilities for LIBS, for which a library of 332 standards was developed. The BU electronics boards interface with the rover and control the instrument, returning data to the rover. 3 = $$ full-width at half-maximum peak resolution in the Raman fingerprint region. Additional circuitry distinguishes pulses reflected from the target from background solar radiation.

The output signal occurs when the distance from the target is equal to the predetermined distance from the target. The optical ranging apparatus includes circuitry for providing a first signal depending upon the light pulses reflected from the target, a second signal depending upon the light pulses from the optical delay fiber bundle, and an output signal when the first and second signals coincide with each other. An optical fiber bundle is used for delaying the optical reference pulses to correspond to a predetermined distance from the target.

A single lens directs ranging pulses to a target and collects reflected light from the target. The optical ranging apparatus includes a pulsed laser light source for generating target ranging light pulses and optical reference light pulses. A proximity fuze system includes an optical ranging apparatus, a detonation circuit controlled by the optical ranging apparatus, and an explosive charge detonated by the detonation circuit.
