Multi-Zone Diffractive Mask for Fine Control of Light Amplitude and Phase

This invention is a mask that can be used in an optical setup to diffract an amount of light based on wavelength. The mask is placed within the focal plane to solve the size-chromaticity problem by using this phase technique. This will achieve better resolution and high start to planet contrast. Background: In the study of the Sun's corona, light...

Birefringent Coating to Remove Polarization Dependent Phase Shift

This technology is a method designed to remove unwanted phase shifts from optical instruments to improve their performance. The method involves the manufacture and application of a layer, or multiple layers, of birefringent materials (materials with two distinct refractive indices) such that the unwanted phase shift is removed from the optical instrument. Background: Optical...
