FRAME 成像技术

The FRAME imaging technology offers the unique ability to acquire and store multiple exposures in one frame of a standard camera sensor. This new Frequency RecognitionAlgorithm for Multiple Exposures (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

• 超高速成像
• 瞬态三维成像
• 同时，多光谱成像

超高速成像
Together with researchers from Lund University LaVision has developed a FRAMEimaging setup for high speed shadow imaging. The FRAME illumination 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.

瞬态 3-维成像
Coded light sheets at different spatial locations are used in combination with FRAMEimaging technology for 3D laser imaging of e. g. 3D concentration fields of LIF species in flames.

同时多光谱成像
Performing multispectral imaging with FRAME allows 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.
