Abstract

We demonstrate coherent imaging through a phased array of single-mode optical fibers. Specifically, we show that two laboratory point sources located within the individual-fiber single-mode acceptance angle can be resolved. Such techniques could eventually enable direct imaging with arrays of small collecting telescopes.

Figures (5)

Fig. 1.
Fig. 1.

Illustration of the spatial filtering property of single-mode fibers. Only the average phase in each subaperture can propagate through the single-mode fibers. A tilted wavefront from an off-axis source is thus encoded in the phases across the fiber array.

Fig. 2.
Fig. 2.

Optical layout. The input pupil is defined by the input DM, and the exit pupil lies at the output DM.

Fig. 3.
Fig. 3.

Focal plane image of a beam from a single fiber.

Fig. 4.
Fig. 4.

Image for a single unphased frame showing the speckled image (upper frame), and the average of many frames with random phases (lower frame).

Fig. 5.
Fig. 5.

Images with cophased array. The secondary “planetary” source is below and left of the brighter primary “stellar” source (upper frame). In the lower frame the secondary source has been turned off.
