The measurement of particle velocities in cosmic ray experiments has largely been made by counters which determine the total amount of Cherenkov light emitted by a radiator material. Here we discuss a far more accurate technique which measures the angle of emission of individual Cherenkov photons by imaging the emission cone onto a ring. This approach has the advantage of supplying a velocity estimate from each detected photon and a large reduction in the effects of background light. As an example, we shall discuss our ring imaging Cherenkov detector (RICH) for high altitude balloon cosmic ray experiments. This instrument combines a 3 m gas Cherenkov radiator with 1.5 m multiplied by 1.5 m of position sensitive photon detectors based on TMAE gas mixtures. The photon detector assembly detects individual photons with a quantum efficiency of 10 - 20% in the UV region of the spectrum. The use of VLSI electronics provides individual readout of 18,000 1 cm by 1 cm pixels. The future application of this technique in cosmic ray instruments also is discussed.
