32 Incoherent fluorescence digital holographic microscopy using transmission liquid crystal lens US15026785 2014-09-29 US09891585B2 2018-02-13 Gary Brooker; Nisan Siegel; Joseph Rosen
A new optical arrangement that creates high efficiency, high quality Fresnel Incoherent Correlation Holography (FINCH) holograms using transmission liquid crystal GRIN (TLCGRIN) diffractive lenses has been invented. This is in contrast to the universal practice in the field of using a reflective spatial light modulator (SLM) to separate sample and reference beams. Polarization sensitive TLCGRIN lenses enable a straight optical path, have 95% transmission efficiency, are analog devices without pixels and are free of many limitations of reflective SLM devices. An additional advantage is that they create an incoherent holographic system that is achromatic over a wide bandwidth. Two spherical beams created by the combination of a glass and a polarization sensitive TLCGRIN lenses interfere and a hologram is recorded by a digital camera. FINCH configurations which increase signal to noise ratios and imaging speed are also described.
