US 10,483,076 B2 · Apparatus, method and system for the calibration of a streak camera

Abstract

The present disclosure claims an apparatus, a method and a system for the calibration of a streak camera. A plurality of fiber optic cables is bundled together such that the input ends and the output ends of the fibers are grouped together. Each fiber in the bundle has a distinct and characteristic time taken for light to traverse from the input end to the output end known by the observer. This characteristic time depends on the physical and optical properties of the fibers selected. Calibration light is collected by the fiber input face and travels through the individual fibers in a characteristic time. Individual light pulses will subsequently be detected by the streak camera which converts the time profile of the incoming light pulses into a spatial profile. An observer can compare the observed spatial separation profile to an expected spatial separation profile for calibration.

Dependent claims

An apparatus integrated into a streak camera for real-time calibration of a streak camera during acquisition of each streak camera observation, comprising:

a fiber bundle, comprising
a plurality of fibers having an input face and an output face,
the plurality of fibers being made of a material selected on a basis of supporting fiber-optic transmission,
wherein the plurality of fibers comprises at least a first fiber and a second fiber,
wherein a light travel time is defined as the time taken for light to travel from the input face to the output face of the fiber,
wherein at least one time difference between light travel times is known;
and
wherein after acquisition of each streak camera observation, processing light signals emitted from said output face of said fibers through the streak camera's varying electric field to convert the light signals' temporal profile to a spatial profile, comparing the spatial profile, acquired at the same time as the streak camera observation, to a known calibration profile in order to correct for unwanted drift, amplitude variation and phase variation for each streak camera observation.
