ILDA - 1998 Amsterdam Meetings
The first Advanced Technology Workshop (ATW) was held
at the New York City ILDA meeting. It was designed to bring laserists a
close-up look 'under the hood' at how the the technology in our industry
works. There were a few presenters who spent lots of time delving into the
nuts and bolts of the technology.
Company: B&W Tek
Sean Wang presented new compact solid-state lasers for laser display applications. Most of these are small diode-pumped, solid-state green YAG lasers. A a red laser was also shown.
Last year Dirk introduced his low-cost closed-loop scanning system dubbed the "CATWEAZLE" system. At that time, the system was only capable of scanning at around 18K. This year, he presented the latest version of the CATWEAZLE which scans at 30K+ scan speeds. Dirk has kept the price in the $1000 US range.
Ante Uglesic demonstrated a number of new accessories for Pangolin’s Lasershow Designer software. He showed a new low-cost, high-performance hardware desk-style interface for use with Pangolin’s Live! controller. This desk is particularly well suited for clubs and discos. He also demonstrated some QuadMod accessories that provide DMX-512 and ISP capability.
Company: New Wave
Derek presented his Sync-Master Live Control console and software for use with Pangolin's Lasershow Designer software. The Sync-Master was introduced at last year's Pangolin User Group meeting and has been continually improved since that time.
Bill Arkin presented improvements to his SpectraScan Suite of software accessories for use with Pangolin Laser Software. This includes his LD Graphic Converter which will convert any computer graphic image from any vector format (BMP, WMF, CDR, DXF, etc.) to a laser frame. He also showed a text converter program that converts any TrueType font, including non-english and italic fonts, to laser frames. To read the Holo Spectra handout, click HERE
Bob Ash wins the prize of being the first person to complete a fully solid-state RGB laser projector. This projector outputs roughly 100mW of white light and runs from a standard wall outlet.
Company: Creative Laser Productions
A veteran of the ATW, Peter presented diffraction gratings once again. This year, Peter has been hard at work in the lab and has emerged with yet another grating innovation – so called polyphase diffraction gratings. This is a special grating process where two or more grating patterns can be combined onto one substrate. Peter is now making two grating disks available; the first has four different grating patterns available in segments while the second has 6 tracks each with a different grating pattern. These gratings make the selection of multiple grating effects simple.
Dirk is continuing his push into the laser product arena with a scan-fail safeguard circuit dubbed the CAT-safe. This board is unique in that it uses a microprocessor to aid in detection of scanner failures. It can detect many more failure modes than most other scan-fail systems and it controls the PCAOM to blank the beam when a failure is detected.
Company: Laser System Europe
Awouters presented the new C-10 Universal Corrector. This is a Geometric Correction system housed in a one-unit-high rack mount enclosure. Geometric corrections include Scale, Invert, Position, Keystone and Shear. The C-10 also has a built-in test pattern generator, scan-signal safety circuit and colour mapper.
Greg presented the Universal Geometric Corrector (UGC) from LSDI. This is a Geometric Corrector which is available as either a stand-alone Printed Circuit Card or as a one-unit-high rack mount enclosure. Geometric corrections include Scale, Invert, Position, Keystone, Shear, Linearity, Bow-line, and Pincushion.
Company: Laser Show Systems
Laser Show Systems has researched acousto-optic beam deflection and its use in entertainment laser projectors for over four years. This research has lead to the first practical entertainment product to use these devices. The system has been used at the 850th anniversary of Moscow show and has been seen at various trade shows and exhibitions. This system has also received a variety of technical awards.
If there was an award for show-stopping presentation, it would definitely go to Samsung for their Laser Video and Show projector. This is the first laser based video projector of its kind which does both NTSC and PAL video, as well as classic vector-style laser graphics and abstracts. Unlike many others, who use a dye laser for red, Samsung has created a colour space converter so that they can get perfect television colour reproduction from a single Argon/Krypton (whitelight) laser.
