Title: Instrument for measuring shape of optical pulse
Inventor: SAKURAI TAKAO
IPC: G01M11/02
Filed: 1994-08-15
Abstract: PURPOSE:To measure the time-base waveform of an extremely short optical pulse with high resolution by detecting the waveform on one side of an optical pulse to be measured branched into two paths by using a photoconducting element equipped with a pair of electrodes and the auto-correlation waveform of the other side by sampling the optical pulse by giving a time lag to the pulse. CONSTITUTION:One side 9A of an optical pulse 9 to be measured branched into two paths by means of an optical branching means (beam splitter) 30 is reflected by a fixed mirror 31 after going straight on and condensed through a mirror 33 and lens A. The condensed light is cast on the electrode 12 of a detecting means (photoconductor) and the means 1 operates as a detector by photoelectrically converting the light. The other side 9B of the pulse 9 reaches the mobile mirror 32 of a light delaying means 21 after it is reflected at an angle of 90 deg.. The autocorrelation waveform of the pulse 9B is detected by sampling electric signals obtained at the electrode 12 at multiple points while the mobile mirror 32 is moved by the time equal to the time for moving from the minus side to the plus side of the pulse width of the pulse 9 in the same optical path and the waveform of the pulse 9 is found by performing deconvolution calculation (18) on the auto-correlation waveform.

Title: Infrared mirror
Inventor: FUNABIKI NOBUO
IPC: G02B5/28
Filed: 1994-08-11
Abstract: PURPOSE:To obtain stable and high reflectance without influences of contamination and scratches of a gold film and to produce a mirror at a low cost by forming a chromium film on a glass base body and controlling the thickness of the film to a specified range. CONSTITUTION:This IR mirror is obtd. by forming a chromium film 11 of 10-50Angstrom  thickness on a glass base body and forming a gold film 12 o on the chromium film. Since the chromium film 11 is formed to <=50Angstrom  thickness, it is possible to allow light beams to enter not the gold film 12 but the glass base body and to transmit through the chromium film 11 to be reflected by the gold film 12. When the chromium film 11 is formed to <=50Angstrom  thickness, most of light entering the glass base body transmits through spaces among chromium particles in the chromium film 11, and then the light is reflected by the gold film 12. Thus, higher reflectance is obtd. However, it is not preferable to form the chromium film 11 to <=10Angstrom thickness because the adhesion strength with the base body decreases and the film is easily peeled. Therefore, preferable thickness of the chromium film is 15 to 25Angstrom .

On the basis of the physical quantity relating to the degree of the operated intensity variation, a main control equipment detects the position in the detecting direction of the position detection mark M.  Thereby, on the basis of the physical quantity relating to the degree of the operated intensity variation, the position in the detecting direction of the position detection mark can be surely detected, when an optical image of low contrast only is obtained.

Filed: 1985-09-27
Abstract: PURPOSE:To improve the using efficiency of a CPU and a bus and to simplify and scale down a device by continuously DAM-transferring plural data blocks at different addresses through one CPU's access. CONSTITUTION:The CPU presents the start address of each data block and a number of transfer words in each block to the address register 7' of a controller and a transfer word number register 8', respectively. Then a data selector 12 selects the output of the register 7', outputs it to an address bus from an address buffer 11 and executes a memory access control. Simultaneously the data selector inputs the output to an arithmetic circuit composed of two EOR circuits 13 and an incrementer 14, inputs the arithmetic result to the registers 7' and 8' and subtracts one from the contents in the register 8'. Then these actions and the memory access are repeated by updating the contents in the register 8' to attain the continuous DMA transfer, and the device is simplified and scaled down accordingly.
