TheFRAMEimaging technology offers the unique ability to acquire and store multiple exposures in one frame of a standard camera sensor. This newFrequencyRecognitionAlgorithm forMultipleExposures (FRAME) imaging concept uses an image-coding strategy, where different exposures are given a unique structural code allowing multiple on-chip exposures before readout. At the end of such a superimposed recording each image is unlocked by its unique structural code. This on-chip recording of structural coded images opens up a variety of new measurement schemes such as
instantaneous 3-dimensional imaging
simultaneous, multispectral imaging
Ultra-high-speed imaging Together with researchers from Lund University LaVision has developed aFRAMEimaging setup for high speed shadow imaging. TheFRAMEillumination unit consists of 4 pulsed LEDs firing a sequence of 4 structural coded illuminations at a frequency of up to 1 MHz. A standard still camera captures on-chip all 4 exposures. After readout a post-processing procedure decodes the multi-exposure recording into the 4 time-separated snapshots.

The temporal resolution and frame rate ofFRAMEimaging are determined by the light source. Using e. g. femtosecond lasers in combination with aFRAMEprojector will permit video imaging at several trillion frames/s – using a single standard high resolution camera!

Instantaneous 3-dimensional imaging Coded light sheets at different spatial locations are used in combination withFRAMEimaging technology for 3D laser imaging of e. g. 3D concentration fields of LIF species in flames.

Simultaneous, multispectral imaging Performing multispectral imaging withFRAMEallows the simultaneous recording of images with different wavelength information. For example, species-specific LIF processes in biological samples can be recorded parallel in time for higher throughput screening.
