Abstract
The present invention relates to a system and method for digital holographic microscopy. According to an aspect of the invention there is provided an off-axis digital holographic microscope comprising: a light emitter configured to provide a divergent light beam; a sensor position to receive light from the light emitter in a first path and a second path, and thereby to detect a holographic image; a reflector positioned partially in the divergent light beam so that light that encounters the reflector extends towards the sensor in the first path, and light that does not encounter the reflector extends towards the sensor in the second path; and a support structure configured to support a sample in the first path or the second path.
Claims8
An off-axis digital holographic microscope, comprising:
- a light emitter configured to provide a divergent light beam comprising a first portion and a second portion;
- a sensor positioned to receive the first portion of the divergent light beam from the light emitter in a first path and the second portion of the divergent light beam in a second path, and thereby to detect a holographic image;
- a reflector positioned partially in the divergent light beam so that the first portion of the divergent light beam that encounters the reflector is reflected towards the sensor in the first path, wherein the second portion of the divergent light beam that does not encounter the reflector extends directly from the light emitter to be incident on the sensor in the second path;
- and
- a support structure configured to support a sample in the first path or the second path.
A method of performing digital holographic microscopy, comprising the steps of:
- emitting light from a light emitter to provide a divergent light beam comprising a first portion and a second portion;
- providing a reflector partially in the divergent light beam so that the first portion of the divergent light beam that encounters the reflector is reflected towards a sensor in a first path, wherein the second portion of the divergent light beam that does not encounter the reflector extends directly from the light emitter to be incident on the sensor in a second path;
- supporting a sample in a support structure in the first path or the second path;
- and
- receiving light at a sensor from the first path and the second path, and thereby detecting a holographic image.
