I came across this article about some of the technology used to scan four suits of Henry VIII’s armor from various times in his life.

From TCT Magazine:

Henry VIII Reverse Engineered by The Scan Team & Konica Minolta

Royal Armouries are staging an exhibition in conjunction with Historic Royal Palaces (HRP) at the Tower of London to mark the 500th anniversary of his coronation. The exhibition will offer an accurate illustration of the King throughout his reign. Fortunately a number of Henry’s armours have survived. These armours were custom made and tailored to fit the King at various stages of his life. By examining these it is possible to see Henry’s true size from when he was a young, athletic man through to his later years.

The team at Royal Armouries took the innovative decision to scan different armours using non-contact laser scanning technology. This would give them completely accurate 3D models of the armours which would enable them to “reverse engineer” the monarch. The scanned armour would also be used to create 3D computer images for the production of real time interactive displays. It was also hoped that the highly accurate but non-invasive measurement would reveal details in the armours that would not be possible through visual examination. Royal Armouries appointed The Scan Team to carry out the scanning and subsequent data processing with the scanning exercise taking place at two locations: Royal Armouries Museum in Leeds and the Tower of London. The armours presented The Scan Team with a number of unique challenges.

The Scan Team scanned four armours and a number of additional components. These armours were the Silvered & Engraved Armour (1515), the Foot Combat Armour (1520), the Tonlet Armour (1520) and the 1540 Armour with its additional components.

Ultimately it is Royal Armouries intention to use the data to make further interactive displays and to produce accurate replicas for hands-on research and study. It is hoped this work will offer a more accurate and detailed impression of one of England’s most notable monarchs.

The data provided in the scans has given Royal Armouries far greater insight into the methods of manufacture. Peter Armstrong, Director of Royal Armouries, said: “The scanning work carried out to date on the Henry VIII armours has already given Royal Armouries a new and unique perspective into their construction. Being able to journey back over 500 years and see the actual hammer blows made by some of the finest armour makers who ever lived, has brought the objects to life. This work will not only play a major part in the international Henry VIII: Dressed to Kill exhibition at the Tower of London in 2009, but will increase the Museum’s knowledge of this iconic king’s armour for generations to come.”
