Abstract: PURPOSE:To simultaneously measure guantum efficiency and multiplication constant in a plurality of wavelength bands, by light sources, of which the lights have a plurality of different wavelength bands and modulated in amplitude by sine waves having different frequencies, and a photo detector output circuit at every frequency band. CONSTITUTION:The light having different wavelengths lambda1, lambda2 from light source 1, 2 are modulated in amplitude by sine waves having different frequencies f2, f2 and condensed to the light receiving surface of a photo detector 5 to be measured through a synthesizer 3. Now, when a light signal is incident to the element 5, a photocurrent is generated corresponding to said light signal and an AC current containing the frequencies f1, f2 flows. This AC current is separated into respective frequencies by LPE 11 and HPF 15 and the photocurrent values of the respective frequency components are measured by indicators 13, 17. Quantum efficiency can be calculated by the AC component powers of the wavelengths lambda1, lambda2 incident to the element 5 and the photocurrent values measured by the indicators 13, 17. Further, magnification constant can be calculated by the photocurrent values of the frequency components f1, f2 under a bias voltage condition becoming magnification constant of 1 and the photocurrent values when bias voltage becoming a prescribed magnification region is applied.

Title: Long-focus depth high-resolution irradiating optical system
Inventor: KAWADA SATOSHI
IPC: G02B27/09
Filed: 1990-11-02
Abstract: PURPOSE:To form a beam spot which is narrow and long along an optical axis by providing an Axicon optical element to converge a coherent light flux along the optical axis for forming an intensive light spot on the light axis. CONSTITUTION:An optical system consists of a laser light source 1, a concave lens 2 and a convex lens 3 which constitute a beam expander, and an Axicon prism 4. A coherent parallel light flux emitted from the light source 1 is enlarged by the beam expander and emitted into the Axicon prism 4. A light flux emitted from the Axicon prism 4 all proceeds to the direction of intersecting a light axis, so that an interference area 5 is formed as shown by a hatching, where the light fluxes coming from all directions are always in phase on the optical axis and so brightness is increased there by phase competition and darkness occurs at positions apart from the optical axis because of out-of-phase. It is thus possible to form a light spot which is long and narrow along the light axis in the interference area.
