JOURNAL FREE ACCESSAs the digital SLR market has long been awaiting for more affordable model, Canon has developed the “EOS Kiss Digital” based on the key concepts of high image quality, compact and light weight, simple and easy operation and full of advanced shooting features. Moreover, dedicated EF-S 18-55 f/3.5-5.6 USM standard zoom lens was developed at the same time, and its combination made the product more appealing in compactness, light weight and low price. Since its world-wide introduction in the market of September 2003, it has been enjoying very large sales. In this article, we will explain the background of its product development and elemental technologies, and then make reviews on its marketing strategies and how the product affected the digital SLR market.View full abstractDownload PDF (3530K) -

JOURNAL FREE ACCESSWe carried a function of the camera shake compensation using a CCD shift on DiMAGE Al. The biggest strong point of this method is that a camera shake compensation function can be added to the camera itself taking advantage of the high performance of the lens, without changing the optical design of the existent lens. To get the good response and highly precise drive, we developed an Ultrasonic Linear Actuator and a slider mechanism individually for this system.View full abstractDownload PDF (1528K) -

JOURNAL FREE ACCESSIn a camera having a retractable lens barrel wherein the distances between the lens groups thereof are reduced when at a fully-retracted position, there are limits as to how far the camera can be miniaturized, especially in regard to making the camera slimmer. In order to solve this problem, we have developed a “sliding lens system” in which one lens group is moved outside of the optical axis when the lens groups are fully retracted.In this paper, we describe an ultra slim digital camera which uses this mechanism and has a 3x optical zoom lens system.View full abstractDownload PDF (1556K) -

JOURNAL FREE ACCESSThis paper reviews the specific nature of nanophotonics, i.e., a novel optical nano-technology, utilizing local electromagnetic interactions between a small number of nanometric matters and optical near field. The size- and position-controlled fabrication of nano-scale structures is demonstrated using near-field optical chemical vapor deposition and size-dependent optical desorption.View full abstractDownload PDF (3983K) -

JOURNAL FREE ACCESSNear-field optical lithography is explained as a nano-processing. We achieved a high aspect ratio resist pattern with near-field optical lithography that uses a surface imaging technology known as bi-layer resist technology. This technique is appropriate for the creation of relatively simple patterns such as grating or nano-dots and is expected to have uses in the manufacture of DFB (distributed feedback) and DBR (distributed Bragg reflector).View full abstractDownload PDF (3688K) -

JOURNAL FREE ACCESSMicrosystems and MEMS (Micro Electro Mechanical Systems), which integrate functional elements in different domains such as mechanics, electronics, chemistry, optics and biotechnology, are the fundamental technology to support a highly-networked information society, an aging society and an eco-friendly society in the 21st century. A three dimensional microfabrication technology utilized synchrotron radiated X-ray is expected to play an important role as one of the promising technology to realize Microsystems and MEMS. The basic and recent progress of this technology is reviewed in this article.View full abstractDownload PDF (5648K) -

JOURNAL FREE ACCESSWe introduce reflective optical elements fabricated by photofabrication technique using a photographic film, which we have been studied. A gray mask made of a photographic film is used for exposing photopolymerizable resin to fabricate a threedimensional base of an optical element. The surface of the base is covered with reflective film to implement the reflective optical element. We describe the features of the optical element and the processes to make the gray mask. Also we describe the processes of the reflective optical element. A prototype convex mirror and that of concave mirror are fabricated and their three-dimensional surfaces are evaluated. Focusing by the fabricated concave mirror is experimentally demonstrated. Finally, an advantageous applications of the reflective optical element fabricated by photofabricated technique is mentioned.View full abstractDownload PDF (3382K) -
