- ‘So it is likely that this is actually a double star, a binary which is very close in separation that may be the mechanism that generates the columniation.’
- ‘The photorefractive creates an index grating that couples light from one beam to another effectively compensating for any less than stellar phase-front negating any need for complicated optical alignment, spatial filtering, and columniation.’
- ‘The diffracted beam columniation depends on the variable detector distance from the fixed scattering volume.’
- ‘Lamp positions adjust for maximum columniation and optimum coverage.’
