Was the use of lenses by painters a monopolized prerogative of their guild, accidentally forgotten after the guilds dissolved?
Bacon studied the propagation of light through simple lenses and is credited as one of the first to have described the use of lenses to correct vision.
He recently published his findings in a lavishly illustrated book, "Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters" (Viking Studio) and participated in a BBC television documentary in which he demonstrated the use of lenses.
While invariably following a settled, stable photographic style, essentially naturalistic in its use of lenses and light, Rivette is in love with appearance as much as the French tradition that includes Lartigue, Cartier-Bresson and Renoir, father and son.
We've seen the use of lens-mounted displays in the current prototype, but the patent also describes alternatives including "a laser or LED source and scanning system [that] could be used to draw a raster display directly onto the retina of one or more of the user's eyes".
In concentrating photovoltaic (CPV) systems the incident solar radiation is multiplied by a factor equal to the concentration ratio, with the use of lenses or reflectors.
Here, through the slow intensification of performance, and then also through a very subtle use of the camera: use of lenses, use of lighting...not trying to avoid the claustrophobia, but trying to take advantage of it.
While several high-throughput imaging platforms have been successfully demonstrated so far [4] [13], the main stream for this application involves the use of lens-based conventional optical microscopes which can only provide a limited field-of-view (FOV) of e.g., ≤1mm2, and therefore require mechanical scanning to provide a larger imaging FOV.
This minimizes chromatic aberration problems, which are inevitably associated with the use of lenses for white light as well as the optical alignment procedure of the detector itself.
