Scope

Quantitative phase imaging measures the optical path a specimen imposes on light, and that single measurement carries a long way. It gives dry mass and refractive index in a living cell, surface figure and film thickness on a semiconductor wafer or a glass substrate, and — through the same phase retrieval — structure at atomic resolution in electron tomography.

The symposium is built around the measurement rather than the specimen. Talks run from optics and reconstruction algorithms through biology and medicine to materials, metrology and inspection, and we would rather the programme were broad than tidy.

Invited speakers

All six invited speakers are confirmed, listed alphabetically by surname. All invited talks take place on Friday, 20 November.

Talk titles and abstracts will be added as they become available.

Registration

Register

Complimentary conference dinner places are offered to advance registrants on a first-come, first-served basis, subject to availability. The current reservation is for 50 people; dinner capacity is separate from registration capacity.

Venue and travel

The meeting is held at The Chinese University of Hong Kong. The scientific sessions and posters will be in Ho Sin-Hang Engineering Building (SHB), Room 603. For travel or visa-support coordination, contact Qihang Zhang.

The local team is coordinating hotel arrangements and a possible group discount at Hyatt Regency Hong Kong, Sha Tin. Booking instructions will follow.

The symposium is in person only — there is no online attendance. Bringing the community into one room for a day is the point of the meeting, and remote participation has not served that well in the past.
