Abstract:
1. An apparatus for optical imaging of an object, the apparatus comprising: a pair of substantially flat, light transmitting plates mounted to be essentially vertical and parallel to one another; a flexible optical matching fluid reservoir adapted to be filled with optical matching fluid and adapted to immerse therein said object; a positioning mechanism for circumferentially adjusting position of said plates about said object and adjusting a relative spacing between said plates while remaining essentially vertical and parallel to one another, said plates being adapted to apply pressure to said object while the object is located in the reservoir and immersed in said matching fluid so as to form essentially a parallelepiped with said optical matching fluid and the object to obtain a desired geometry of said object and said optical matching fluid; a source and detector arranged outside said plates for emitting light into and receiving light from said object immersed in the reservoir and surrounded by said optical matching fluid; and a supporting mechanism comprising a rigid rim and a supporting platform, the supporting mechanism surrounding an upper perimeter of said reservoir, said supporting platform comprising an area surrounding said cavity for receiving said rigid rim, said rigid rim being formed in one piece and being inserted into a fold around said upper perimeter.
