Title:
METHOD AND SYSTEM FOR ACQUIRING CARS SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2022/224999
Kind Code:
A1
Abstract:
A system (1) comprises an optical path (10) for irradiating a part of a target (5) with pulses of Stokes light (11) and pump light (12), and pulses of probe light (13) with pulse widths larger than pulse widths of the pulses of the Stokes light and the pump light; a modulator (70) that is configured to control relative temporal relationships between the pulses of the probe light and the pulses of the Stokes light and the pump light within the pulse width of the probe light; and a detector (50) configured to detect CARS spectrum (15).
