The true image area that can be used for recording microscopic objects in hybrid holographic microscopy can be increased by elimination of the conjugate image and the zero-order image. We therefore added two shutters and one phase modulator to the electro-optical holographic recording system so that we could change the recording parameters and evaluate four methods of eliminating the conjugate image and the zero-order image. We found that the methods that use only the phase modulator require the recording of fewer holograms than do the methods that use the shutters and also provide reconstructed images that are less noisy.
Experimental examination of the accommodative responses to a stereoscopic 3-D display found that accommodation was elicited by convergence and moved to the stereoscopic distance of the 3-D image. Immediately after the depth of the target was changed, the magnitude of response was smaller than that for a real target, but when the subjects fixated on the 3-D images, the responses were in almost the same position as the position of 3-D images. Measurement of accommodation response time after the subjects viewed 3-D images showed an afteraffect on the far-to-near accommodation response. The results are discussed in terms of the mismatch of accommodation and convergence in stereoscopic 3-D images and of the interaction between accommodation and convergence in human eyes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
