Abstract

The invention relates to a handheld laser—based perfusion imaging apparatus comprising a light source and an imaging device which are arranged in a fixed orientation to each other in said apparatus. The light source is configured for projecting a beam of coherent light onto a measurement field. at a predetermined. distance spaced. apart from. the apparatus. The imaging device is configured for recording speckle intensity maps of the measurement field and/or images of Doppler shifted light of the measurement field. The light source is configured to provide a substantially spherical wavefront or a substantial planar wavefront, at least at the measurement field. Preferably, the apparatus with the light source that provides a substantial planar wavefront, comprises a gimbal mount. Furthermore, the invention relates to a method for measuring a perfusion in a tissue using the handheld laser—based perfusion imaging apparatus as described above.
