Abstract: The Fresnel structure of the invention is variable with regard to both angular pitch and curvature. A stretchable membrane (51) forms a surface which describes a Fresnel zone. Altering angular pitch is achieved by actuating a first side (49) relative to a second side (55). Such actuation causes the membrane (51) connected to both (49) and (55) to lengthen. Said lengthening causes a first fluid (47) on a first side of the membrane and a second fluid on a second side of the membrane to be reshaped with regard to angular pitch. Altering curvature is achieved by altering the pressure of the first fluid (47) relative to the pressure of the second fluid (53). The unit reliable produces variable Fresnel structures which can be altered with regard to angle and curvature. Transmissive and reflective structures are described. Refraction, diffraction, deflection, and reflection can all utilize these variable Fresnel structures.

Abstract: A reflector comprises a frame (1) over which is stretched a flexible sheet of reflective material (2) to define a curved reflecting surface of pre-determined geometry. The frame (1) defines arcuate sections (3, 4, 5, 6) portions of which support the sheet (2) and lie on the surface of pre-determined geometry. At least one of the arcuate sections (3, 4, 5, 6) is deformable to displace the respective sheet supporting portion and thereby adjust the tension in the flexible sheet (2).

Abstract: A flexible mirror (10) comprising a reflectively coated membrane (12) overlying a circular chamber (14) has its membrane (12) tension controlled around the membrane periphery. The membrane periphery is secured by circularly-extending clamp surfaces formed between two rings (21, 24) which are axially movably mounted by three bolts (22) and associated springs (23) which provide for coarse tension control when the membrane (12) is pulled down against the circular aperture (13) of structure (15). Fine tension control is provided by one ring (24) containing a segmented inner ring (32) the segments of which are independently operated by bolts (33) causing the segments to abut an O-ring (30) overlying membrane (12) and squashing the membrane (12) to a greater or less extent into an annular groove or channel (31) formed in the ring (21). The effectiveness of the tension control is monitored interferometrically.

Abstract: A reflector arrangement, especially for solar collectors, having a sheet (3) of reflecting material which is stretched to radiation-concentration shape in an airtight covering (1) of at least partly transparent material in that it divides the covering into two chambers (7, 8) within which different air pressures are maintained. The air pressures also maintain the covering (1) stretched around the sheet (3). The sheet (3) preferably is secured in a rigid frame (5) which, in turn, is connected to the covering (1). Radiation incident upon the sheet (3) is concentrated to a small area within which a radiation absorber is provided. The reflector arrangement is very easy to manufacture and also is inexpensive and can be quickly mounted, also by unskilled persons.
