[f. Gr. ὁδό-ς way + -scope.]
1. Microscopy. (See quot.)
1915J. W. Evans in Jrnl. Quekett Microsc. Club XII. 613 It is frequently desirable to examine simultaneously the optical properties of a number of different directions in a mineral... For this purpose the microscope is..converted into an optical instrument in which every point in the image corresponds not to a point in the object under examination, but to a direction along which light traverses that object in parallel paths. Such an instrument may be conveniently described as a hodoscope or path viewer, a term which is to be preferred to the word ‘konoscope’ employed by some authors.
2. Physics. An assembly of particle detectors used for observing the paths of cosmic-ray and other particles.
1950Physical Rev. LXXVIII. 715/1 For the purpose of analyzing the shower phenomena in a hodoscope set it would appear desirable to use as large a number of narrow counters as possible. 1967Nuclear Instruments & Methods LI. 1/1 An experiment on mu meson pair production was performed..utilizing a 192 unit hodoscope. For each hodoscope counter only the detection or non-detection of a particle (and not pulse height) was recorded. |
