Claim:
1. A system to perform downhole fluid analysis, the system comprising: a depressurizer to be positioned down hole in a geological formation to depressurize a formation fluid in the geological formation, the depressurization of the formation fluid to cause bubbles to nucleate in the formation fluid; an imaging processor to be positioned downhole in the geological formation, the imaging processor to capture imaging data associated with the formation fluid, to process the imaging data downhole, and to detect nucleation of the bubbles in the formation fluid based on the imaging data; a capillary tube to hold the formation fluid while the imaging data is captured; a controller to report measurement data via a telemetry communication link to a receiver to be located outside the geological formation, the measurement data including a bubble point of the formation fluid calculated based on the detected nucleation of the bubbles; and a laser scanner to generate at least two separate 2D laser sheets sequentially, each at a different depth, across the formation fluid for contact with the bubbles present at each of the different depths within the formation fluid, the captured imaging data including at least two separate 2D image planes corresponding to the at least two separate 2D laser sheets, wherein the measurement data includes a gas-to-oil ratio of the formation fluid, the gas-to-oil ratio based on a ratio of a volume of the bubbles in the formation fluid to a volume of the formation fluid, the volume of the bubbles determined based on a summation of areas of the bubbles along a length of the capillary tube indicated in the imaging data.
