Japanese Device Uses Laser Plasma to Display 3D Images in the Air

first_img Explore further A collaboration of the Japanese National Institute of Advanced Industrial Science and Technology (AIST), Keio University and Burton Inc. has produced a device to display “real 3D images” consisting of dot arrays in empty space. Copyright 2006 PhysOrg.com Many previous displays in 3D have been virtual images on 2D planes which, due to human binocular disparity, appear as 3D. However, the limitation of our visual field and the physical discomfort caused by wrongly identifying virtual images makes these displays less than perfect.The new device uses the plasma emission phenomenon near the focal point of focused laser light. By controlling the position of the focal point in the direction of the x-, y-, and z-axes, real 3D-images in air (3D-space) can be displayed.

This is because our monitors are unable to display them.Keio University and Burton Inc. noticed that, when laser beams are strongly focused, air plasma emission can only be induced near the focal point. So, they experimented by fabricating a device to display 2D-images in the air. The images are constructed from dot arrays produced by a technique combining a laser light source and galvanometric mirrors. To form 3D-images in the air, the scanning of the focal point in the depth direction along the laser optical axis is essential. However, to do this, the quality of the laser and the technique for varying the position of the focal point must be improved. This explains why we do not yet have the technology to display 3D images.By modifying the 2D image device with a linear motor system and a high-quality and high-brightness infrared pulse, the AIST, Keio University and Burton Inc. created a spatial display of “real 3D images” consisting of dot arrays.The linear motor system can vary the position of the laser focal point by high-speed scanning of a lens set on the motor orbit. Incorporation of this system makes the image scanning in the direction of the z-axis possible. For scanning in the x and y axis directions, conventional galvanometric mirrors are used.The high-quality and high–brightness infrared pulsed laser (repetition frequency of pulse: approximately 100 Hz), enables plasma production to be more precisely controlled, resulting in brighter and higher contrast image drawing. Furthermore, the distance between the device and drawing points can be extended by several meters.The emission time of the laser pulse light is approximately a nanosecond (10-9 sec). The device uses one pulse for each dot. The human eye will recognize the after-image effect of plasma emission from displays up to 100 dot/sec. By synchronizing these pulses and controlling them with software, the device can draw any 3D objects in air. Overview of the 3D-image spatial drawing device.

South Eastern Railway conducts antilittering drives

first_imgKolkata: The South Eastern Railway (SER) conducted special anti-littering drives on Saturday and Sunday at Santragachhi and Howrah Stations. During the two-day drive around Rs 27,000 was collected as fine.According to the SER, on Saturday officers and ticket checking staff were deputed in and around of Santragachhi Station’s platforms. The intention was to sensitise the passengers travelling not to make the platforms and other areas of the stations dirty by spitting or other means. Each passenger found littering the area was fined up to Rs 500.

Sources informed that people found spitting was charged Rs 100 and people found throwing garbage on railway tracks or at platforms were fined Rs 500. On Saturday, the SER collected Rs 13,000 from the persons caught littering the area. Around 100 people were prosecuted including some without ticket passengers. On Sunday, the drive was conducted at the New Complex of Howrah Station. Around 108 persons were prosecuted for littering the station area and the SER has collected approximately Rs 14,000 as fine. The SER has announced that such drives will continue as a surprise check across the SER jurisdiction in future. “Such type of drives will continue at different stations under SER jurisdiction. The teams will consist of Commercial Inspector with Ticket examiner and RPF staff as it was on Saturday and Sunday,” said spokesperson from the SER.last_img read more

Madhyamik exam curriculum being reviewed Official

first_imgKolkata: The Syllabus Reforms Committee of Madhyamik — the Class 10 state board examination in Bengal — is reviewing its existing curriculum but not mulling any immediate change, a top official said on Monday. It has undertaken the process of reviewing the entire curriculum for Classes 9 and 10, the committee official said here. “The committee will suggest if there is need for any change in any part (of the syllabus), and the department and board officials will assess its report and implement the suggestions if they deem it necessary,” he said. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseTo a question, the committee official said, since no changes in Madhyamik syllabus can be effected within a period of five years, there is no immediate case for a “sudden change” in the curriculum. The 2022 Madhyamik examination is the earliest when such a change can be introduced, he said, adding, the review exercise is a periodic process. The Syllabus Reforms Committee had in 2015 suggested changes in the Madhyamik syllabus, recommending more multiple choice questions (MCQ) and text-based reading.last_img read more
